Introduction

What is a Middle Bearing Seat?

A middle bearing seat (also called central bearing housing or mid shaft support) is a structural component that stabilizes rotating shafts in drivetrains, pumps, or industrial machinery. It prevents axial displacement and reduces vibration in applications like truck propeller shafts, centrifugal pumps, and conveyor systems.

Industry Synonyms:

  • Central Bearing Housing

  • Mid Shaft Support Bracket

  • Drive Shaft Center Bearing
