R162152310 Original Rexroth Linear Bearing Block
BALL RUNNER BLOCK CARBON STEEL KWC-055-SNH-C2-H-2
- Size 55
- Format SNH: Width = slimline, length = normal, height = high
- Runner block body made of unalloyed steel CS
- Preload class C2: Medium preload
- Accuracy class H: High
- Without ball chain
- Preserved
- Without initial lubrication
- Without attachment element, left (front reference edge)
- Without attachment element, right (front reference edge)
- 45° angular lube nipples loosely attached.
- Runner block body in standard version
- Overall length of the runner block = 159.0 mm
- Interchangeability: The runner block and the guide rails can be combined with each other with every accuracy.
Technical Advantages
Optimized for precision linear motion systems, the SNH-format linear bearing carriage achieves:
- Dynamic load rating C100 = 109,000N (24,504 lbf) at 100,000m travel
- Ultra-low friction coefficient μ=0.002-0.003 with SS standard seals
- Moment stiffness ML0=3,690Nm (3,262 lb-ft) in all 4 load directions
