OEM Linear Actuator Solutions: Custom Screw Jacks for Industrial Motion Control
OEM Linear Actuator Solutions: Custom Screw Jacks for Industrial Motion Control
When your production line demands a linear actuator that exactly matches your load, speed, and mounting requirements, off-the-shelf components often fall short. Shandong Dezhou Jinyu Machinery Co., Ltd. — known as JINYU — is a professional manufacturer specializing in the design and production of worm gear screw jacks, trapezoidal screw jacks, ball screw jacks, and related linear actuation solutions. With a factory spanning 20,000 m², 258 employees, and an annual output exceeding 10,000 units, JINYU offers comprehensive ODM and customization services for industrial buyers who need not just components, but engineered solutions.
When Standard Linear Actuators Are Not Enough
Many industrial buyers face a common dilemma: the required stroke, lifting capacity, gear ratio, or environmental protection level does not align with standard product catalogs. In applications such as metallurgy, precision automation, medical equipment, and heavy lifting platforms, a generic linear actuator can lead to compromised performance, shorter lifespan, or even safety risks. The market has responded: worm gear screw jacks alone held 38.5% of the screw jack segment in 2025 due to their self-locking and heavy-load capabilities (Dataintelo, Persistence Market Research). Yet, even this dominant type often needs adaptation for a specific project.
Industry Context: The Shift Toward Customized Screw Jacks
The global screw jacks market was estimated at USD 14.26 billion in 2024, with a projected CAGR of 5.91% through 2035 (Market Research Future). The Asia-Pacific region accounted for 42.3% of linear motion revenue in 2025, led by manufacturing growth in China and India (Grand View Research). As automation lines become more specialized, ODM and customization capabilities have become decisive factors in supplier selection. Buyers are moving beyond simple product comparison and evaluating whether a manufacturer can adapt size, load, stroke, gear ratio, voltage, logo, and material to their exact specifications.
JINYU's OEM/ODM Solution: A Complete Customization Framework
JINYU provides ODM (Original Design Manufacturing) production services. This means the company does not merely carry out assembly — it can engineer the screw jack around your application requirements. Customization is available for the following parameters:
- Size — overall dimensions and mounting interfaces
- Load — from 1 kN to 120 t (depending on series)
- Stroke — up to 2000 mm (SWL series)
- Gear ratio — options such as 5:1, 6:1, 8:1, 10:1, 24:1, 32:1
- Voltage — compatible with various motor specifications
- Logo & branding — for OEM partners
- Material — including stainless steel screw jack variants for corrosion resistance
JINYU also offers both electric and manual screw jack configurations within the same product family. The factory has a monthly capacity of 10,000 units, and every unit undergoes 100% quality testing before shipment.
Step-by-Step: How to Procure Custom Screw Jacks from JINYU
Step 1: Requirement Definition — Provide your target load, stroke, speed, working environment, and any special material needs (e.g., stainless steel for food or offshore applications).
Step 2: Design & Technical Proposal — JINYU's 10-person R&D team reviews the specifications and proposes the optimal series (SWL, JWM, or JWB) with custom gear ratio and mounting.
Step 3: Quotation & Sample — Lead time is typically 30–45 days for custom orders. MOQ is 1 unit, so prototypes are feasible.
Step 4: Production & Quality Control — 100% pre-shipment test on every unit. Certifications (ISO 9001, ISO 14001, ISO 45001, CE) ensure compliance with international standards.
Step 5: Delivery & Support — Available under FOB or CIF terms, with remote after-sales support.
Proven Use Case: Italian Industrial Automation & Metallurgy
JINYU's JWM series trapezoidal screw jacks have been used for 8 years in a synchronous lifting system for a Danieli strip finishing line in Italy. The client, an industrial automation OEM and metallurgical equipment manufacturer, deployed 80 units. The system demonstrated stable multi-point synchronous lifting, high positioning accuracy, reliable self-locking, and long-term continuous operation in a harsh metallurgical environment. Highlights include self-locking safety, low maintenance, energy saving, and a compact structure that perfectly adapted to the production line process. This case illustrates JINYU's capability to deliver customized solutions for heavy-duty European projects.
