KO Vibrating Screen Bearings
Vibration-duty spherical roller bearings selected by cage, clearance, speed, acceleration, load, lubrication, contamination, and failure history.
Bearings Built for Vibration
Vibrating screen bearings face unique challenges that standard spherical roller bearings are not designed to handle: high-frequency cyclic loading, rapid acceleration changes, and constant vibration-induced stress on cages and rollers. Screen-duty selection should confirm cage, clearance, speed, acceleration, load, lubrication, and contamination before quotation.
What Makes Them Different
Machined Brass Cage with F80 Clearance
The most critical differentiator: our vibrating screen bearings use a machined brass cage with F80 (extra-large) oil clearance. This combination:
- Absorbs vibration energy without cage fracture
- Allows controlled roller skew under acceleration
- Supports lubrication film review under cyclic loads
- Helps review cage risk when stamped-steel cage bearings failed in screen applications
Enhanced Internal Geometry
- Optimized roller profile: Modified logarithmic profile reduces edge stress during misalignment events
- Reinforced inner and outer rings: Extra material at critical sections for fatigue resistance
- Special heat treatment: Through-hardening with additional stabilization for dimensional consistency
Performance
- Shock load review against the failed model and screen duty
- Service-life review after acceleration, speed, lubrication, and fit are known
- Downtime risk review based on cage, clearance, and lubrication history
Applications
- Mining vibrating screens (primary, secondary, tertiary)
- Aggregate screening plants
- Recycling and waste processing shakers
- Coal preparation screens
- Sand and gravel classification
Available Sizes
Common sizes in 22300, 22200, and 23200 series. Bore range 40mm–200mm. Both cylindrical and tapered bore. Standard C4 clearance for screen applications.
Urgent Replacement Requests
Vibrating screen failures often create downtime pressure. Send the screen model, current bearing, clearance, cage type, speed, acceleration, quantity, and destination so we can check the complete designation, available supply options, lead time, and replacement boundaries.
