Blower Bearings
Bearing sourcing for blower shafts where speed, vibration, noise, and heat all need review before quote.
Blower Bearings Sourcing Notes
Blower bearing RFQs often start from a failed unit, but the quote needs more than a model number. Speed, temperature, and vibration history help avoid repeat failure.
For B2B replacement and RFQ work, confirm the model, review candidate alternatives, and prepare the technical details buyers normally need before a quote.
Selection Checks
- Provide blower type and operating speed.
- Clarify whether the bearing position is locating or non-locating.
Specification Review
| Item | Typical RFQ Value | Why It Matters |
|---|---|---|
| Buyer intent | Blower repair or spare set | Common for Roots and centrifugal blowers. |
| Technical check | Speed and vibration | High speed can change clearance and lubrication choice. |
Common Applications
- Industrial fans
- Roots blowers
- Centrifugal blowers
- Process air systems

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. |
| blower type | Provide the blower type value, drawing note, or clear photo if available. | blower type helps TFL review the request in the correct model, application, document, and quotation context. |
| speed | Operating RPM, variable speed range, or machine nameplate if RPM is unknown | Speed affects lubrication, heat generation, cage suitability, and clearance review. |
