Frequently Asked Questions (FAQ)
"22320" designates a heavy-series spherical roller bearing with a 100mm bore diameter (20 × 5). "CC" indicates stamped steel cages with a flangeless inner ring and guide ring, while "W33" represents an annular lubrication groove with three lubrication holes in the outer ring.
Yes. Spherical roller bearings are designed with two rows of symmetrical rollers, enabling them to accommodate exceptionally high radial loads alongside significant bidirectional axial loads simultaneously.
The outer ring features a common spherical raceway that allows the inner ring and roller assembly to swivel dynamically. This compensates for shaft deflection and housing misalignment without increasing friction or temperature.
The 22320CCW33 bearing supports grease lubrication up to 1,400 r/min and oil lubrication up to 1,800 r/min. The outer W33 feature allows efficient relubrication directly into the roller tracks during operation.
We supply C0 (Normal), C2, C3, C4, and C5 radial internal clearance options depending on the thermal expansion and operating conditions of your machinery.
All bearings are warranted against manufacturing defects in material and workmanship for 12 months from the shipping date, provided installation, lubrication, and operation adhere to specified engineering guidelines.
