Jinyu Machinery details screw jack lineup for linear actuator precision

Shandong Jinyu Machinery has published the technical range for its screw jack and ball screw actuator families, including load, speed, stroke and protection ratings tied to CE and ISO certifications. The disclosure matters for industrial buyers comparing load-holding, high-speed and customized linear motion systems for automation, metallurgy and other heavy-duty applications.

Why it matters: - Jinyu Machinery is positioning its linear actuator lineup around measurable engineering limits, not broad product claims. - Buyers can compare load, speed, stroke, ingress protection and certification scope before placing orders. - The product range targets heavy-duty lifting, automation lines, robotics, logistics and metallurgical applications.

What happened: - SHANDONG JINYU MACHINERY CO., LTD published technical specifications for three worm gear screw jack families and one ball screw actuator family. - The company is based in Dezhou, China, at No. 8, East of Yangguang Road, Tianqu Industrial Park, Decheng District, Dezhou City, Shandong Province. - The published CE certificate for the ball screw actuator scope was issued on 13 June 2025 and is valid through 12 June 2030. - The certificate cites EN ISO 12100:2010 and EN 60204-1:2018. - The company was founded in 1984. - Jinyu operates a 20,000 m² plant, employs 258 people and has a 10-person R&D team. - Annual output is 10,000 units. - Roughly 30% of production is exported to the EU, the United States and Asia.

The details: - The SWL series is listed as a self-locking, trapezoidal and manual or electric screw jack. - SWL lifting capacity runs from 2.5 t to 120 t. - SWL lifting speed runs from 0.1 m/min to 0.6 m/min. - SWL stroke ranges from 100 mm to 2,000 mm. - SWL gear ratios include 6:1, 8:1, 10:1, 24:1 and 32:1. - SWL operating temperature ranges from -20 C to 80 C. - SWL protection ratings run from IP54 to IP55. - The JWM series is listed as a trapezoidal and low-speed screw jack. - JWM lifting capacity runs from 1 kN to 1,000 kN. - JWM lifting speed runs from 0.2 m/min to 1.8 m/min. - JWM stroke ranges from 100 mm to 1,500 mm. - JWM gear ratios include 5:1, 6:1, 8:1, 10:1, 20:1, 24:1 and 32:1. - JWM operating temperature ranges from -20 C to 100 C. - JWM protection ratings run from IP55 to IP65. - The JWB series is listed as a ball screw jack and high-speed screw jack. - JWB lifting capacity runs from 5 kN to 500 kN. - JWB lifting speed runs from 0.5 m/min to 5 m/min. - JWB stroke ranges from 100 mm to 1,500 mm. - JWB gear ratios include 5:1, 6:1, 8:1 and 10:1. - JWB operating temperature ranges from -20 C to 80 C. - JWB protection ratings run from IP55 to IP65. - The three series share a common material set: 40Cr and 45# steel screws, HT200 cast iron housings, CuSn6Zn6Pb3 bronze nuts, 40Cr and 42CrMo gears, and 45# carbon steel shafts. - The company also manufactures worm gear reducers and processes reducers and gear reducers to customer-supplied materials or drawings. - The JWB family is the ball screw actuator offering in the published range. - JWB is listed for high-speed automation production lines, robotic equipment, precision lifting platforms, logistics conveying, aerospace auxiliary equipment and CNC machine tools. - Jinyu offers ODM production and customization for size, load, stroke, gear ratio, voltage, logo and material. - Stainless steel screw jack variants and electric or manual drive options are available as customized configurations. - The company lists a minimum order quantity of one unit, a lead time of 30 to 45 days and a monthly capacity of 10,000 units. - Quality control is described as 100% testing, with pre-shipment testing as the acceptance criterion. - Delivery terms are FOB or CIF, payment terms are 30/70, and after-sales support is provided remotely.

Between the lines: - The product split suggests a clear tradeoff between load-holding and speed. - Trapezoidal screw families emphasize self-locking behavior and broader ratio choices. - The ball screw family emphasizes higher travel speed and precision-oriented applications. - The published certificate coverage signals an effort to make the range usable in export and regulated industrial markets. - The Italian strip-finishing reference gives Jinyu one documented multi-point synchronous lifting use case outside China, but the long-term performance claim rests on company records. - Jinyu’s cited market position also depends on how buyers weigh capacity, lead time and certification against larger global competitors.

What's next: - Procurement teams will likely compare load, stroke, ratio, protection class and documentation before specifying a standard or customized unit. - Buyers needing load retention without continuous motor torque are likely to favor the self-locking trapezoidal families. - Buyers needing higher travel speed and precision are likely to favor the JWB ball screw actuator family. - The main test for Jinyu’s published ranges will be whether the same envelopes hold across customized builds and export projects.

The bottom line: - Jinyu is marketing screw jacks as specification-driven industrial components, with published performance bands, certification and customization aimed at buyers who need measurable linear motion rather than generic actuator claims.
