Browning PB50-1 Pillow Block Bearing With Lubricator

Browning PB50-1 Pillow Block Bearing With Lubricator is a Browning-mounted bearing housing designed to accept a 1-3/16 in bore shaft and to provide grease lubrication through an integrated lubricator. The PB50-1 designation appears in Browning’s mounted bearing lineup and in reseller listings for this 1-3/16 in bore pillow block configuration, signaling a compact, pre-lubricated housing intended to support rotating shafts in industrial machinery. The lubricator feature enables periodic re-greasing without disassembly, helping to extend bearing life and simplify maintenance in continuous-operation settings. Some listings describe the PB50 variant as including a bronze bushing, reflecting common configurations seen in the market. In practice, this unit is chosen for installations where reliable shaft support, straightforward mounting, and accessible lubrication are priorities, aligning with Browning’s long-standing approach to robust, serviceable pillow block bearings.
