THK FBW2560R+320L Compact Recirculating Linear Guide Rail

Description:

The THK FBW2560R+320L Linear Guide Rail is a compact slide pack linear motion guide designed to provide smooth, low-friction linear travel in space-constrained automation equipment. It incorporates a precision recirculating ball slider on a 320 mm rail, delivering quiet operation, corrosion resistance, and reliable positioning accuracy. Commonly installed in semiconductor equipment, medical devices, laboratory instruments, inspection systems, and compact industrial automation machinery. Maintenance teams and system integrators use this linear guide for equipment repair, replacement, and new machine construction.

Applications:

The THK FBW2560R+320L belongs to the THK FBW Series Slide Pack compact linear guides. The "2560" model identifies the guide size, while "320L" specifies an overall rail length of 320 mm. This compact guide integrates a miniature recirculating ball slider and rail assembly to provide precise linear motion with low operating noise and high corrosion resistance. The suffix "R" is not publicly documented by THK for this model family and should not be interpreted without the original engineering drawing or product specification.
