Browning PB-RB4 XC2380C Pillow Block Bearing Assembly

The Browning PB-RB4 XC2380C Pillow Block Bearing Assembly is a pre-mounted shaft-support unit that pairs Browning’s PB-RB4 pillow block housing with a Timken XC2380C insert bearing, delivering a ready-to-install solution for machines that require a rigid, centerline-aligned bearing mount. This combination integrates the housing and insert bearing in a single assembly, eliminating the need to source components separately when building or refurbishing equipment. Distributor listings identify the model as PB-RB4 and note that this assembly is discontinued, which can complicate replacement planning and may prompt consideration of alternative Browning or Timken options. The XC2380C insert bearing referenced here is a Timken insert bearing designed to fit Browning’s pillow block format, providing insert-bearing functionality within a compact housing. Availability may be limited due to its discontinued status.
