Overview
The Misumi LHBB30 linear ball bearing pillow block is a precision-engineered bearing housing designed for 30mm shaft linear motion applications. This single-wide standard-style pillow block features an integrated seal for contamination protection and is pre-configured to mount directly to workpieces through four mounting holes, eliminating the need for custom housing fabrication.
Key Features
- 30mm inscribed circle diameter (shaft size) for standard linear rod applications
- Sealed design provides protection against contamination in industrial environments
- Standard single-wide format optimized for single-axis linear motion
- Pre-drilled mounting holes enable direct installation to machine frames and assemblies
- Grease-lubricated construction for low-maintenance operation
- Compact 72mm overall length for space-constrained applications
