Spherical roller bearings
About this category
- Self-alignment
- up to ±1.5° of misalignment
- Load
- very high radial, axial in both directions
- Bore
- cylindrical or tapered 1:12 (K)
- Usual clearance
- C3 — when mounted on a sleeve
Spherical roller bearings are self-aligning — they absorb housing misalignment and shaft deflection of a few degrees without raising raceway stress. That is why they work in screens, crushers, industrial fans and paper machines, where the frame flexes and the shaft is long.
They carry very high radial loads and substantial axial loads in both directions. Tapered bore versions (K) mount on an adapter sleeve, which allows fitting on a plain shaft and adjusting clearance during assembly.
What to look at when selecting
- 01Check whether the assembly really needs self-alignment — with a rigid housing a cylindrical or ball bearing is cheaper.
- 02A tapered bore with an adapter sleeve simplifies mounting on a long shaft without shoulders.
- 03When mounting on a sleeve choose C3 clearance: drawing the bearing up reduces the operating clearance.
- 04Sealed versions save a lubrication system in dusty environments.

- CN, C3 or C4 — what the clearance suffix meansA C3 suffix does not mean a “better” or “heavier duty” bearing. It is the internal clearance before mounting — a reserve consumed by the interference fit on the shaft and by thermal expansion. Get it wrong one way and the bearing seizes; the other way it runs loud and beats.
- How to read a bearing designationA designation has two parts: the basic number says what the bearing is and how big, the suffixes say how it is built. The basic number is shared across manufacturers; the suffixes each writes their own way. Both are below, with examples from our catalogue.
Common questions
- When is an adapter sleeve used?
- When the shaft is plain, with no locating shoulder, or when the bearing must sit at an arbitrary position. The sleeve also lets you control clearance during mounting — you tighten the nut and measure the clearance reduction with a feeler gauge.
- What clearance for sleeve mounting?
- C3 as standard. Drawing the bearing onto the taper expands the inner ring and reduces operating clearance — with normal CN it is easy to drop below the minimum and overheat the bearing.
