Import Ball Screw — Buy in Bulk from Supplier in China

The ball screw is a precision mechanical actuator that converts rotational motion to linear motion with minimal friction, using a threaded shaft and recirculating ball bearings. Weiyuan Precision Technology Co., Ltd offers this component for applications requiring repeatable accuracy, with typical lead options in the 5 mm to 50 mm range and standard diameters from 12 mm to 80 mm, compatible with CNC machinery and industrial automation systems.

Constructed from hardened steel alloys, the screw and nut assembly is ground to tight tolerances, achieving C3 to C7 precision grades for positional accuracy under load. Surface treatments such as black oxide or zinc plating provide corrosion resistance, while the ball return system ensures consistent torque and smooth operation across the stroke length. Industry-standard preload classes from 0 to 3 allow tuning for rigidity and backlash reduction.

These screws are specified in linear motion systems for machine tools, semiconductor equipment and robotic arms, where load capacities often span 1 kN to 100 kN and speeds reach 60 m/min. Buyers typically confirm dynamic load ratings, critical speed limits and lubrication requirements before integration. Trade terms for bulk orders are negotiated directly with Weiyuan Precision Technology Co., Ltd, with packaging usually in wooden crates to prevent deformation during transit.

Weiyuan Precision Technology Co., Ltd operates from Block A, North-Cycle Road Back Shang Wu Community in Shiyan Town, Baoan District, Shenzhen, China. The supplier is classified as an imported-tier provider with a harbor trust tier, indicating established logistics capabilities for cross-border trade. However, the company’s response rate is currently listed as 0.00, suggesting buyers should expect delays in initial inquiries and plan for direct follow-ups.

The profile confirms a focus on mechanical components, with no additional claims about certifications, production scale, or client base provided. Buyers are advised to verify manufacturing standards, quality control processes, and any applicable industry certifications directly with Weiyuan Precision Technology Co., Ltd, as these details are not specified in the available information.
