Product Features
- Spherical outer ring design accommodates misalignment and provides self-aligning capability for extended bearing life.
- Set screw locking mechanism secures the bearing to the shaft for reliable operation under varying loads.
- Double-lip seal design effectively retains lubrication and keeps contaminants out.
- Dimensionally interchangeable with UC204 bearings from SKF, NTN, NSK, FAG, and KOYO.
- Compact 20 mm shaft bore with 47 mm outside diameter fits standard housing units.
- Reliable performance in both industrial and agricultural applications.
Installation Notes
- Confirm shaft diameter is exactly 20.00 mm (0.787 in) before installation.
- Tighten the M6x1.0 set screws evenly and securely to prevent bearing movement on the shaft.
- Verify housing bore matches the 47 mm outside diameter of the bearing.
- Ensure the spherical outer surface seats correctly in the housing to allow full self-alignment function.
- Apply appropriate grease before operation and maintain regular lubrication intervals.
