SealMaster NP-31 2-Bolt Base Pillow Block Ball Bearing 1-15/16" Bore

The SealMaster NP-31 Base Pillow Block Ball Bearing is used to support and align rotating shafts in related mechanical drive systems. It is installed on equipment frames where the 1-15/16-inch bore fits the shaft allowing smooth rotation while maintaining stable positioning under load. The housing is mounted to a base structure using two bolts and securely holds the bearing insert for operation. In HVAC systems, it is commonly used in fan assemblies, blower drives, and air handling equipment to reduce friction support shaft alignment, and maintain consistent mechanical performance during continuous operation.
