Features

• consisting of a ball bearing insert UC 311 and a cast iron housing F 311
• 4-hole flange bearing design allows installation in a variety of applications and is suitable for very high radial loads
• the housing is made of cast iron and therefore inexpensive and robust
• the bearing insert has an extended inner ring with grub screws
• The flange bearing is mounted on the shaft using two grub screws
• smooth running and good behavior with tilting due to the extended inner ring
• static misalignments can be compensated up to an angle of 2°
• two-piece sealing system: with sheet steel washer reinforced rubber seal inside; outside additionally with upstream slinger made of sheet steel for high mechanical protection against foreign matter
• lubricated for life; under normal operating conditions relubrication is not required
• housing with integrated lubrication hole
• to protect against corrosion, the housing is painted; the bearing insert and the mounting surface are treated with corrosion protection oil
