Spherical Roller Bearing Technical Data
Use the model tables and technical guides to identify the complete bearing, compare design data, and check mounting and operating constraints before changing a bearing or approving a replacement.
Tables and Selection Guides
Internal Clearance
Compare CN, C3, C4, fits, thermal effects, vibration, speed, and required running clearance.
Suffix Chart
Separate bore, clearance, cage, lubrication, sealing, and design markings without treating suffixes as universal across brands.
Cage Types
Record the complete cage/design reference and compare it with load, speed, vibration, lubrication, and application duty.
Tapered Bore
Distinguish cylindrical, K, and K30 bores and identify the shaft and mounting information required.
Adapter and Withdrawal Sleeves
Compare sleeve function, bearing bore, shaft diameter, locknut, washer, shoulders, and mounting arrangement.
HS Code and Export Documents
Check the six-digit HS heading and prepare destination-specific invoice, packing, and compliance information.

A Practical Selection Sequence
| Step | Confirm | Do not assume |
|---|---|---|
| 1. Identify | Complete marking, brand, model, and every suffix | A base model includes every required feature. |
| 2. Measure | d / D / B, shoulders, fillets, shaft, housing, and available space | Boundary dimensions alone approve a replacement. |
| 3. Compare design | Bore, cage, clearance, seals, lubrication features, C/C0, speed, and mass | Suffix conventions or internal designs are universal. |
| 4. Check duty | Loads, speed, temperature, fits, vibration, contamination, lubrication, and alignment | A catalog speed or rating is the machine's operating limit. |
| 5. Confirm order | Selected design, quantity, origin, inspection, packing, documents, and lead time | Availability and documents are identical for every supply option. |
