Single Linear Roller Bearing Pillow Blocks
Single Roller Bearing Pillow Blocks (SPB series) are high-load-capacity linear bearings featuring a robust housing and a single set of three opposing rollers that grip the shaft from both sides and the top. One of the side rollers is eccentric, enabling adjustments for shaft misalignments, increased speed, extended travel, and vibration damping.
- Inch & metric sizing interchangeable to industry standards
- Self-aligning and adjustable; one side roller is eccentric
- Navigates joined shafts and rail assemblies with ease
- Less friction + larger rolling surface = faster, quieter operation
- Part numbers can indicate lubrication ports (TG) and/or scrapers (S) or linear carriage locks (LCL)
- Available for shaft diameters from 0.5" to 3.0"
- Loads up to 12,500 lb (55,602 N); 8X more load capacity than linear ball bearings
- Reliable in dirty environments; roller bearings push dirt aside

- Reliable in dirty environments; roller bearings push dirt aside
In contaminated environments, the roller bearings push particulates out of the way or roll seamlessly over them. Large rollers in the Roller Pillow Block system are well suited for long travel applications. The copper scraper option (part number -S) adds to the ability of these linear bearings to deal with dirt and clutter.
