Caged Ball LM Guide Wide Rail Model SHW

Since its LM rail has a wide structure with a low center of gravity, this 4/way equal load LM Guide achieves a high Mc moment.

  • Long-term maintenance free
  • High accuracy
  • Self-adjusting capability
  • Low-profile LM Guide
  • 4-way equal load
  • Wide
  • Suited for single rail

Features

Structure and Features

Balls roll in four rows of raceways precision-ground on the LM rail and LM block and are circulated by ball cages and end plates incorporated in the LM block.
A wide and highly rigid LM Guide that uses ball cages to achieve low noise, long-term maintenance-free operation and high speed.

Wide, Low Center of Gravity

THe Model SHW, which has a wide LM rail and a low center of gravity, is optimal for locations requiring space saving and large MC moment rigidity.

4-way Equal Load

Each row of balls is placed at a contact angle of 45° so that the rated loads applied to the LM block are uniform in the four directions (radial, reverse radial and lateral directions), enabling the LM Guide to be used in all orientations and in extensive applications.

Self-adjustment Capability

The self-adjustment capability through front-to-front configuration of THK’s unique circular-arc grooves (DF set) enables a mounting error to be absorbed even under a preload, thus to achieve highly accurate, smooth straight motion.

Low Dust Generation

Use of ball cages eliminates friction between balls and retains lubricant, thus achieving low dust generation.
