Overview
The SKF LBAR 12-LS is a sealed linear ball bearing engineered for precision motion control across automated manufacturing, positioning systems, and mechanical assemblies. This compact bearing features recirculating ball tracks that enable smooth, low-friction linear movement with unlimited stroke capability. The unit arrives new in box and is ready for immediate installation.
Key Features
- Sealed design with single-side contact seal (LS designation) for dust and contamination protection
- Recirculating ball track design minimizes friction and provides smooth linear motion
- Compact form factor suitable for space-constrained applications
- 12 mm bore diameter fits standard precision shafts
- Low-maintenance operation with factory pre-lubrication
- Compatible with SKF linear bearing systems and rail guides
