• Sealmaster ER-15 Cylindrical OD Bearing, Setscrew Locking Collar, Light Contact Felt Seals, 15/16" Bore, 52 mm OD, 1-3/8" Width
This Sealmaster ER Series ball bearing insert with setscrew locking collar and felt seals is suitable for use in mounted bearing housings to carry shafts with radial or radial and thrust loads, such as in material handling. The outer bearing surface has a snap ring that sits in a groove to locate the insert within its housing. This bearing insert is made from ASTM International 52100 high carbon steel and its rings are coated with black oxide for corrosion resistance. 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. 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. A collar extends from the bearing inner ring and setscrews lock the collar and bearing onto the shaft.
