Browning VPB-231 Pillow Block
The Browning VPB-231 is a standard-duty, 1 15/16" bore diameter pillow block bearing designed for high-performance industrial HVACR and power transmission applications. Built with a robust cast iron housing, this unit features the BOA concentric locking mechanism, which ensures 360-degree holding power and maintains near-perfect concentricity to minimize vibration and shaft marring. The bearing insert is constructed from 52100 bearing steel with a black oxide finish on the inner ring for enhanced corrosion resistance. To ensure long-term reliability in contaminated environments, the VPB-231 utilizes a single lip contact seal and flinger, effectively retaining lubricant while shielding the internal ball path. With a dynamic load rating of 7,889 lbs and a maximum speed of 3,000 RPM, this two-bolt pillow block is engineered for heavy-duty fan, blower, and motor drive assemblies where quiet operation and shaft alignment are critical for maintaining system uptime and mechanical integrity.
Key Benefits- Concentric Alignment: The BOA locking collar centers the shaft within the bore, drastically reducing high-speed vibration and noise in air-handling units.
- Superior Sealing: The contact and flinger seal design provides a multi-stage defense against dust and moisture, extending the service life of the 52100 steel bearing.
- High Load Capacity: Engineered for standard-duty applications with a 5,216 lb static load rating, providing stability for large industrial shafts.
- Optimized Housing: Features a powder-coated cast iron surface and a semi-solid base to prevent mounting fatigue and structural buckling under torque.
What is the primary advantage of the BOA concentric lock over a standard set screw?
The BOA concentric locking system provides uniform 360-degree contact around the shaft, which eliminates the shaft offset and burring often caused by traditional set screws, resulting in a more balanced rotation at higher RPMs.
Can the Browning VPB-231 be relubricated?
Yes, this pillow block bearing is equipped with a standard 1/8" NPT grease fitting, allowing for manual relubrication to maintain the lithium complex NLGI 2 grease levels during routine maintenance cycles.
Is this bearing suitable for expansion or non-expansion requirements?
The VPB-231 is a non-expansion (fixed) type bearing. It is typically paired with an expansion-type unit on the opposite end of the shaft to allow for thermal growth without inducing axial stress.
