W2507FA-4-C5T25 Standardized Precision Ball Screw 25 ×25 Large Lead Ball Screw

The NSK W2507FA-4-C5T25 is a FA series large-lead, shaft-end finished ball screw with a nominal diameter of 25 mm, a lead of 25 mm, and an accuracy class of C5.

The FA type W2507FA-4-C5T25 ball screw uses a tube-circulation structure, meaning the balls circulate through a return tube inserted into the nut body. Tube-circulation types are commonly used in medium to large-sized ball screws, featuring smooth operation and uniform force distribution, making them suitable for high-load working environments.

The NSK FA type shaft-end finished ball screw W2507FA-4-C5T25 has the following features:

Standardized shaft end machining allows for direct installation of support units, reducing secondary machining and improving assembly accuracy;

Low operating noise and vibration, suitable for precision and clean environments;

High speed and high-speed feed capability, suitable for automated and high-speed machine tool applications;

Offers a high-precision grade of C5, with high positioning accuracy and repeatability;

A preload structure can be used to achieve low backlash and high rigidity;

Good sealing and lubrication performance, long service life, and short maintenance cycle;

Belongs to a standardized finished product series, with short lead times, facilitating batch design and replacement of equipment.

The NSK W2507FA-4-C5T25 ball screw is commonly used in:

CNC machine tools: feed axes of CNC machining centers, lathes, and milling machines.

Automated production lines: robotic arms and material handling robots.

Precision measuring instruments: coordinate measuring machines, etc.
