Sealmaster ER-24 Ball Bearing Insert 1-1/2″ Bore Size – GPM Surplus This bearing insert is made from ASTM International 52100 high carbon steel and its rings are coated with black oxide for corrosion resistance. Snap ring in outer bearing surface to locate insert within housing The bearing insert has a heat treated inner race for wear resistance and an outer race with a brass land riding retainer that spaces the ball bearings for even load distribution and prevents contact to reduce friction, vibration, and noise. The shield protects the working parts of the bearing from environmental debris that may be introduced and could reduce the ball bearing speed and lifespan. Lubrication grooves and oil holes in the outer bearing ring feed lubrication through the bearing and a tapered race profile allows lubricant to more easily flow back into the raceway. All roller bearings are open, shielded, or sealed.
