Sealmaster MP-43 2-11 16 F45 Pillow Block Ball Bearing Unit

Sealmaster MP-43 pillow block bearing unit features a 2-11/16 in (2.6875 in) bore and a cast-iron housing designed for two-bolt base mounting with a set-screw locking, housing a ball bearing insert with a wide inner race. It employs a felt labyrinth seal to protect the bearing and retain grease while resisting contamination, a common configuration for MP-series units. The MP-43 CXU EPT variant is a fixed (non-expansion) mounting option with a dynamic load rating around 14,839 lb, a maximum operating speed near 2,450 rpm, and a service temperature range from -40 to 200 °F, with typical two-bolt footprint dimensions including bolt centers from 7-7/8 to 10-1/8 in and an overall length near 13 in. These specifications—bore size, housing material, locking method, seal type, and performance ratings—are consistently listed across Sealmaster MP-43 listings from distributors and catalogs.
