Ultra-wide and low center of gravity
The SHW-type LM guide design conforms to that of the HRW type and continues the HRW tradition of wide rails and a low center of gravity. This construction makes SHW-type LM guides the ideal choice for locations where space is very limited and rigidity under Mc moment load is required

4-way equal load rating
This type of LM guide can be used in a wide rage of applications in any position because each row of balls is arranged to the LM block in all four directions (radial, reverse radial, and both lateral directions)

Self-aligning capability
The self aligning capability of THK's unique circular arc groove design (face-to-face/DF) means that mounting misalignment can be eliminated, even when preload is applied, and allows high-precision, smooth linear movement.

Low dust generation
The Cage ball technology construction used in SHW-type bearings provides extremely low levels of dust generation due to ability to retain lubricant.
