Product detail
The Pinsi SFY Ball Screw is a high-speed, end-cap return type precision transmission component engineered for linear motion systems demanding fast, accurate, and durable performance.
The end-cap circulation (end-cap return) design allows compact internal ball return without external tubes, enabling higher rotational speeds and a more compact assembly. The SFY series is tailored for motion systems where speed, stiffness, and smoothness are critical.
Constructed of premium bearing-grade steel (such as 52100), with precision thread rolling or grinding, and integrated dustproof / sealing mechanisms, the Pinsi SFY screw ensures long service life, stable motion, and minimal noise.
Feature
The SFY series supports a range of diameters (e.g., 16 mm, 20 mm, 25 mm, 32 mm, 40 mm) and lead options. Its compact, high-precision performance makes it well-suited for CNC machines, high-speed automation, positioning stages, medical devices, and other precision equipment.
End-Cap Return Design
nternal ball return through end caps, no external ball tubes required — suitable for high-speed operation.
High Speed Capability & High Dm-N Rating
Designed for high rotational speeds with stable performance.
Zero Backlash / High Rigidity
Optimized internal geometry and preload options reduce axial play and enhance stiffness.
Precision & Smooth Operation
Advanced manufacturing (threading, grinding, shot-molding) ensures smooth travel and minimal vibration.
Integrated Dustproof / Seal Design
Effective dust protection around the nut and screw interface for reliability in real environments.
Variety of Diameters & Leads
Available in many size options (SFY1616, SFY2020, SFY2525, SFY3232, SFY4040 etc.)
Compact & Space Efficient
End-cap type allows more compact installation compared to external return types.
Durable Material & Construction
Bearing steel (52100 or equivalent) with precise machining and heat treatment for wear resistance.
