About Tapered Roller Bearings
The rolling elements of a tapered roller bearing are tapered rollers, forming a line contact with the raceways of the inner ring (cone) and outer ring (cup). They are separable bearings, available in both metric and inch dimensions.
They can be made to special dimensional requirements within basic design limitations.
- Capable of carrying high radial loads as well as axial loads in one direction
- Suitable for low and medium speed applications
- Normally mounted in pairs for axial location in both directions
Available Variants
- Single row types — 302, 303, 303D, 320, 322, 323, 330, 331 and 332 series
- Double row type — DRT (details available on request)
- Four row type — FRT (details available on request)
- Precision grade P0 and higher precision grade P6
Suffix Codes
Add these suffixes to the bearing number to specify clearance, cage and bore options.
| Suffix | Meaning |
|---|---|
| A | Modified internal design. |
| AR / RA | Flange on the cup. |
| D | Used with 303 series to denote equivalence to the 313 series of other brands. |
| M | Machined brass cage. |
| P | Polyamide cage. |
| P6 | Dimensional and running accuracy conforming to ISO class 6. |
| Q1–Q4 | Internal reference codes. Contact us for details. |
Typical Applications
- Wheel hubs and axle assemblies
- Gearboxes and differentials
- Rolling mills and heavy machinery
- Machine tool spindles and conveyor drives
Frequently Asked Questions
What sizes are available in the 322 series?
322 series bearings are available from 17mm – 240mm bore, as listed in the dimension table on this page. Each size has its own bearing number for ordering.
What load ratings apply to 322 bearings?
Dynamic and static load ratings vary by size — see the table for the exact rating per bearing number. Larger sizes carry proportionally higher load ratings.
What is the 322 series typically used for?
Common applications include wheel hubs and axle assemblies and gearboxes and differentials, and similar general industrial equipment.
Can tapered roller bearings carry axial load?
Yes — radial load together with axial load in one direction. They are normally mounted in pairs so that axial location is achieved in both directions.
Can I order 322 series bearings with special options?
Yes. Many options are available — see the variants and suffix codes on this page — subject to design and manufacturing constraints. Share your requirement in a quote request.
