Product Variant TFL Bearing
Open Spherical Roller Bearings
Open spherical roller bearing route for buyers deciding between relubrication access, contamination control, speed, application conditions, and sealed alternatives.
Variant: Open
Compare: Sealed SRB
RFQ: Model + environment
Open SRB Sourcing Notes
Open spherical roller bearings are usually considered when buyers need relubrication access, standard open construction, or a replacement review against a sealed bearing alternative. The right choice depends on contamination, speed, temperature, lubrication plan, and maintenance access.
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 whether the buyer needs an open bearing, sealed bearing, or open/sealed comparison.
- Confirm lubrication environment, contamination level, speed, temperature, and application.
- Use the sealed SRB page for sealed-bearing requests and keep this RFQ focused on open-bearing sourcing and open/sealed review decisions.
Specification Review
| Item | Typical RFQ Value | Why It Matters |
|---|---|---|
| Open bearing | Relubrication access | Useful where maintenance access and lubrication control are part of the plan. |
| Sealed alternative | Contamination protection | Review width, seal drag, heat, and fit before substitution. |
| RFQ task | Model, suffix, environment | Application data decides whether open or sealed should be reviewed. |
Common Applications
- Industrial fans

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. |
| environment | Dust, water, slurry, outdoor exposure, high humidity, cement dust, paper mill moisture | Environment affects sealing, grease, corrosion risk, packing, and maintenance interval review. |
