Screw Jack Certification Guide: What ISO 9001, ISO 14001, ISO 45001 and CE Mean for Linear Actuator Buyers
Certification is one of the most concrete ways to evaluate a linear actuator supplier before committing to a purchase. For buyers comparing worm gear screw jacks, ISO 9001, ISO 14001, ISO 45001 and CE certificates provide verifiable evidence of quality management, environmental responsibility, occupational health and safety, and EU regulatory compliance. This guide explains what each certification means for procurement decisions and how to verify them for suppliers such as SHANDONG JINYU MACHINERY CO., LTD.
SHANDONG JINYU MACHINERY CO., LTD is a professional manufacturer based in Dezhou City, Shandong Province, China, specializing in screw jacks, worm gear reducers, servo electric cylinders and electric push rods. The company, founded in 1984, operates a 20,000 m² facility with 258 employees and an annual output of 10,000 units, exporting approximately 30% of its production to the EU, USA and Asian markets.
Why certification matters in screw jack procurement
Certifications serve as third-party evidence that a manufacturer follows recognized standards in its processes. For industrial buyers, they reduce the need to audit every supplier from scratch. A certified supplier has already been assessed by an external body against documented requirements.
For linear actuators and worm gear screw jacks, the relevant certificates typically cover four areas:
- Quality management — ISO 9001
- Environmental management — ISO 14001
- Occupational health and safety — ISO 45001
- EU regulatory compliance — CE
Each certification addresses a different risk. ISO 9001 focuses on consistent product quality and customer satisfaction. ISO 14001 focuses on environmental impact. ISO 45001 focuses on worker safety. CE marking addresses product safety requirements for the European market.
ISO 9001:2015 — quality management for consistent screw jack production
ISO 9001:2015 is the international standard for quality management systems. A manufacturer certified to ISO 9001 must demonstrate that its processes for production, inspection and service are documented, monitored and continuously improved.
For the JWB series worm gear screw jack, the manufacturer holds ISO 9001:2015 certification with certificate number 0350423Q30363ROM, issued by XQCC. The certification is based on the standard GB/T 19001-2016 / ISO 9001:2015 and applies to the manufacture and service of reducers (worm gear reducers, worm gear screw jacks) and accessories. It is valid until 2026-06-11 for the EU market.
What this means for buyers: When a supplier holds ISO 9001, the buyer can expect documented procedures for order handling, production planning, inspection and corrective action. This reduces the likelihood of inconsistent quality across batches.
ISO 14001:2015 — environmental management in manufacturing
ISO 14001:2015 sets requirements for an environmental management system. It covers how a company manages its environmental responsibilities, including waste, emissions and resource use. For buyers, this certification is often relevant for corporate sustainability programs and supply chain policies.
The JWB series worm gear screw jack is certified to ISO 14001:2015 standards under certificate number 0350424E20279ROM, issued by XQCC. The certification is valid from 2024-07-29 to 2027-07-28 and covers the manufacturing and service of worm gear screw jacks. The applicable standard is GB/T 24001-2016 / ISO 14001:2015.
What this means for buyers: ISO 14001 certification indicates that the supplier has a structured approach to environmental management, which can help buyers meet their own sustainability reporting and compliance requirements.
ISO 45001:2018 — occupational health and safety
ISO 45001:2018 is the international standard for occupational health and safety management systems. It provides a framework for reducing workplace risks and improving worker safety. For industrial equipment buyers, this certification is particularly relevant when visiting factories or when long-term supply relationships require stable production conditions.
ISO 45001:2018 certification for the JWB series worm gear screw jack is held under certificate number 0350424S30278ROM, issued by XQCC. It is based on the standard GB/T 45001-2020/ISO 45001:2018 and is valid from 2024-07-29 to 2027-07-28. The scope covers the manufacturing and service of reducers (worm gear reducers, worm gear screw jacks) and accessories for the internationally recognized market.
What this means for buyers: A certified safety management system reduces the risk of production interruptions caused by workplace incidents. It also signals that the supplier operates with a degree of corporate responsibility that matters for long-term partnerships.
CE certification — EU compliance for ball screw actuators
CE marking is a mandatory conformity mark for certain products sold in the European Economic Area. For machinery and related components, CE certification indicates that the product meets applicable EU safety requirements. Buyers importing screw jacks into the EU should verify CE status before finalizing a supplier.
The JWB series worm gear screw jack and ball screw actuators hold CE certification, issued by GTS with certificate number GTSC20250516012-1-01. The certification confirms compliance with EN ISO 12100:2010 (machinery safety — general principles for design, risk assessment and risk reduction) and EN 60204-1:2018 (electrical equipment of machines). It is valid from 2025-06-13 to 2030-06-12.
What this means for buyers: CE certification is essential for EU-bound shipments. It demonstrates that the product has been assessed against recognized safety standards, which also facilitates smoother customs clearance and end-user acceptance.
How to verify screw jack supplier certifications
Certificates are only useful if they can be verified. Buyers should follow a simple verification process:
- Ask the supplier for the latest certificate copies in PDF format.
- Check the certificate number, issuing body, issue date and expiry date.
- Compare the certified scope with the product being purchased — certification may cover specific product types.
- Confirm the certification body is accredited, such as XQCC for ISO certificates or GTS for CE certification.
- Check whether the product model is explicitly named in the certificate scope.
This process is especially important for screw jacks used in automated production lines, lifting platforms, medical equipment, packaging machinery, metallurgical equipment and other applications where failure can cause downtime or safety risks.

The ISO 9001, ISO 14001 and ISO 45001 certificates apply to the manufacturing and service of reducers and screw jacks across all three series. The CE certificate specifically covers ball screw actuators, which corresponds to the JWB series.
Market context: global demand for screw jacks and linear actuators
The global screw jacks market was estimated at USD 14.26 billion in 2024, with a projected CAGR of 5.91% reaching USD 26.82 billion by 2035. The broader linear actuator market was valued at USD 52.67 billion in 2023 and is projected to grow to USD 94.3 billion by 2030, driven by industrial automation.
Worm gear screw jacks held the largest market share in the screw jack segment at 38.5% in 2025 due to self-locking features and heavy-load capacity. The Asia-Pacific region dominated the linear motion market with a 42.3% revenue share in 2025, driven by manufacturing growth in China and India.
For buyers, these trends mean higher demand for verified suppliers. Certification is becoming a baseline requirement rather than a differentiator, especially for EU and international procurement.
Comparison with traditional procurement approaches
Traditionally, industrial buyers relied on long-standing supplier relationships and physical inspections to assess quality. Certifications provide a complementary and more scalable mechanism, but they have boundaries.
The main limitation of certification-based procurement is that certificates reflect processes and systems, not every individual unit shipped. A certified manufacturer should still be evaluated on product-specific parameters, inspection reports and application fit. Buyers should combine certification checks with technical evaluation, sample testing and clear specifications.
In a 2026 procurement context, certification serves as a minimum threshold. It does not guarantee that a specific screw jack model is the optimal choice for a particular load, speed or duty cycle. For that, buyers still need application-specific selection.
Application scenarios and certification relevance
Different applications place different demands on screw jacks, and certification relevance varies accordingly:
- High-speed automation production lines and robotic equipment typically use the JWB ball screw jack for high-efficiency continuous lifting. CE certification supports EU machine builders who must comply with machinery safety directives.
- Metallurgical equipment, hydraulic gates and tooling platforms typically use the JWM trapezoidal screw jack for heavy-load vertical jacking with reliable self-locking. ISO 9001 quality certification is directly relevant because positioning accuracy and material consistency affect operational safety.
- Stage equipment, grain and oil processing, and general industrial jacking typically use the SWL screw jack for stable lifting and fine adjustment. ISO 45001 is relevant to operators who work near or maintain these systems.
In all cases, the certified scope matters. A certificate covering "manufacturing and service" does not mean every product variant has been separately certified to every standard. Buyers should request the certificate scope and confirm product coverage.
Case reference: JWM series in a metallurgical strip finishing line
One documented application of the JWM series involves an industrial automation and metallurgical equipment manufacturer in Italy. The project used 80 units in a synchronous lifting system for a Danieli strip finishing line. The system has operated for 8 years with stable multi-point synchronous lifting, high positioning accuracy, reliable self-locking and long-term continuous operation in a harsh metallurgical environment.
The application highlights self-locking safety, low maintenance, energy saving, compact structure and adaptation to the production line process. For buyers in metallurgy and heavy industry, this case demonstrates how JWM series screw jacks perform in continuous, high-duty applications, and it supports the value of verifying quality certifications before sourcing.

Future outlook: certification as a procurement baseline
As industrial automation expands in Asia-Pacific and other regions, the role of certifications in supplier selection will continue to grow. Buyers should expect that ISO 9001, ISO 14001, ISO 45001 and CE certificates will be standard requirements for suppliers targeting EU and international markets.
In the future, digital verification of certificates may become more common, allowing buyers to validate credentials online in real time. Until then, the most reliable approach is to request certificates directly and verify them against the issuing body.
For buyers planning 2026–2030 procurement cycles, it is prudent to select suppliers whose certifications are current and valid for the duration of the expected supply relationship.
