Vibrating Screen Bearings
Vibration-duty spherical roller bearing route for screen buyers reviewing cage, clearance, speed, acceleration, load, contamination, and failed model 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 bearing RFQs 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 RFQs
Vibrating screen failures often create downtime pressure. Send the screen model, current bearing, clearance, cage type, speed, acceleration, quantity, and destination so TFL Bearing can review common model matching, current availability, production routes, and replacement review boundaries before quotation.
RFQ Details to Send
Send these details so TFL Bearing can review the model, suffix, cage, clearance, bore type, application, documents, and quotation route before confirming current availability or production options.
| RFQ detail | Example | Why it matters |
|---|---|---|
| full bearing model | 22222 EK/C3 W33, 22320 CAK/W33, or photo of the full marking | Identifies the series, size group, bore style, clearance reference, and starting point for quotation review. |
| full suffix / marking | K, K30, C3, C4, W33, CA, CC, MB, 2RS, or full ring marking photo | Suffixes can change bore type, clearance, cage design, lubrication groove, sealing, and replacement risk. |
| cage type | CA machined brass, CC stamped steel, MB machined brass, or unknown with photo | Cage design affects load, vibration tolerance, lubrication behavior, and suitability for screen or crusher duty. |
| clearance class | CN, C3, C4, C5, or current suffix if the clearance is not separately known | Clearance must be reviewed with shaft fit, temperature, vibration, speed, and failure history. |
| bore type | Cylindrical bore, K 1:12 tapered bore, K30 1:30 tapered bore, adapter sleeve reference | Bore style changes mounting method, sleeve requirements, shaft fit review, and replacement compatibility. |
| application equipment | crusher, vibrating screen, fan, gearbox, conveyor pulley, paper machine, or steel mill position | Application context affects load, shock, speed, contamination, lubrication, and document review. |
| quantity | 1 large bearing, 2 pcs for maintenance, 50 pcs distributor stock, or annual demand | Quantity affects quote route, packing, production planning, inspection scope, and freight review. |
| destination | Destination country, port, warehouse, distributor address, or project site region | Destination affects export documents, packing method, shipping route, and trade-term review. |
| required documents | Inspection report, material certificate, COO, RoHS / REACH statement, packing photos, buyer template | Document requirements must be confirmed before quotation because scope depends on order route and buyer template. |
| target timing | Maintenance shutdown date, urgent repair, trial order timing, or normal replenishment schedule | Timing helps separate availability review, production planning, sample validation, and consolidated shipment options. |
