SFE2525 Ball Screw

SFE2525 Ball Screw

Product descriptions

The SFE2525 Ball Screw Assembly is a high-performance linear drive component engineered specifically for applications requiring extreme speed, large lead travel, and maximum efficiency.

As a prominent member of the high-speed SFE series, it features a unique "Square" 1:1 configuration, pairing a rigid 25mm shaft with an aggressive 25mm lead. This geometry allows for rapid linear displacement with relatively low rotational input, enabling travel speeds up to 1 m/s (60m/min). The flanged, single-nut design utilizes a compact "E-Type" internal recirculation system, ensuring quiet operation and a minimized footprint while providing the structural rigidity necessary for dynamic industrial environments.

Key Features:

High-Speed Stability for Long-Stroke Applications
The SFE2525 Ball Screw is the engineered solution for moving loads rapidly over medium-to-long distances. While smaller high-lead screws (such as the 16mm series) are prone to "whipping" at high velocities, the robust 25mm shaft of the SFE2525 provides the necessary column strength to maintain stability over stroke lengths of 1.5 to 2.5 meters.

Efficiency & Acoustic Optimization
Featuring a steep 25mm lead, this assembly converts rotary torque into linear thrust with exceptional efficiency (>95%). The optimized internal ball return system ensures that, even at high rotational speeds, the rolling elements recirculate smoothly. This design eliminates the metallic "rattle" associated with traditional high-lead components, resulting in quiet, consistent operation.

Space-Saving SFE Architecture
The SFE series distinguishes itself by eliminating bulky external recirculation tubes. By routing the balls through integrated end caps, the overall nut diameter is significantly reduced. This allows for lower center heights and tighter machine packaging, making it ideal for compact, high-throughput systems.
