SHS15 LV1SS THK – linear guide carriage (LM block)

What this product actually is

The THK SHS15 LV1SS is a linear guide carriage (LM block) used in precision motion systems, not a bearing in the classic sense. It works together with a linear rail to create smooth, accurate linear movement.

A linear guide system allows controlled motion in one axis with very low friction and high rigidity, widely used in automation, CNC and industrial machinery.

Key features

• 4-row ball system ensures equal load in all directions
• 45° contact angle for balanced load distribution (radial and lateral)
• Self-alignment capability compensates mounting errors
• Caged ball technology reduces noise and friction, increases service life
• Compact LV design for limited installation space
• High precision and smooth linear motion
