Find the right bearing
Match the bearing by its number first. The last two digits show the bore: from 04 upward multiply by 5 to get millimetres (04 = 20 mm, 05 = 25 mm). Then match the outside diameter and width.
- Suffix 2RS means rubber seals on both sides. ZZ means metal shields.
- Check the load: radial (across the shaft), axial (along the shaft) or both.
| Type | Best for | |
|---|---|---|
| Ball | Light to medium radial load, high speed | Shop |
| Cylindrical roller | Heavy radial load | Shop |
| Tapered roller | Radial and axial load together (wheels, gearboxes) | Shop |
| Spherical roller | Heavy load with shaft misalignment | Shop |
| Needle roller | Compact space, high radial load | Shop |
| Angular contact | Combined load at high speed | Shop |
General guidance. Ask us to confirm a bearing before you order.
Choose the cylindrical roller type by the flanges
Cylindrical roller bearings carry heavy radial loads. The letters NU, N, NJ and NUP say which ring has flanges, and that decides how much the shaft can move along its axis.
- Use NU or N where the shaft grows with heat and must slide freely.
- Use NJ or NUP where the bearing must also hold the shaft in position.
| Type | Outer ring flanges | Inner ring flanges | Axial location | |
|---|---|---|---|---|
| NU | Two | None | Free both ways | Shop |
| N | None | Two | Free both ways | Shop |
| NJ | Two | One | One direction | Shop |
| NUP | Two | One plus a loose ring | Both directions | Shop |
Most are sold as a set of inner ring, outer ring and rollers. Tell us the full code.
