Mounted Spherical Roller Bearings
Mounted and housed spherical roller bearing routes for buyers specifying housing type, shaft size, load, quantity, and destination.
Mounting: Pillow / flange
RFQ: Housing + shaft
Intent: Commercial
Mounted SRB Sourcing Notes
Mounted spherical roller bearing RFQs are driven by housing style and shaft fit as much as by bearing series. Buyers should confirm whether the request is for a pillow block, flange mounted, or other housed unit before quotation.
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
- Send housing type, shaft size, current bearing or unit reference, load, and quantity.
- Confirm whether the buyer needs the complete housed unit, the insert bearing, or a replacement review for an existing assembly.
- Use photos or drawings when the housing reference is incomplete.
Specification Review
| Item | Typical RFQ Value | Why It Matters |
|---|---|---|
| Mounted type | Pillow block, flange, or custom housing | Housing style affects fit, mounting holes, seals, and quote path. |
| Shaft data | Shaft diameter and fit | Shaft size is required before a mounted unit can be reviewed. |
| RFQ task | Unit or insert replacement | Clarify whether the buyer needs a complete mounted assembly or only the bearing. |
Common Applications
- Industrial fans
- Conveyor pulleys
- Bulk handling equipment
- Process machinery

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. |
| bearing position | drive side, non-drive side, screen exciter, crusher pitman, fan shaft, gearbox input shaft | Bearing position helps review load direction, vibration exposure, access for lubrication, and failure risk. |
| dimensions | Bore x OD x width, measured bearing sample, or drawing dimensions | Dimensions are a starting check, but they must be reviewed together with suffix and application. |
