NTN 32205 Tapered Roller Bearing 322 Series Metric 25 x 52 x 19.25mm
Available
This is a range of NTN metric tapered roller bearings in three sizes: 25 x 52mm, 40 x 68mm and 140 x 210mm (bore x outer diameter). A tapered roller bearing carries radial and axial load together, which makes it the usual choice for wheel hubs, gearbox output shafts and other duty with combined loading. The bearing is separable and open, so the cup and cone can be fitted separately and the bearing re-greased.
Bearing type: Tapered roller bearing. Load type: Combined radial and axial. Construction: Separable. Sealing: Open.
Available Sizes
3 sizes available — select the exact size you need from the dropdown above. Key figures for each:
| Inner Diameter (mm) | Outer Diameter (mm) | Dynamic load capacity C (kN) | Static load capacity C0 (kN) | Limit Speed With Oil Lub Rpm |
|---|---|---|---|---|
| 40 | 68 | 50 | 65.5 | 7100 |
| 25 | 52 | – | 43 | 9800 |
| 140 | 210 | 365 | 580 | 2100 |
Where This Is Used
- Wheel hubs on trucks, trailers and agricultural equipment.
- Gearbox and drive shafts in industrial and mining machinery.
- Crusher, conveyor and general engineering plant.
Features
- Combined radial-axial: handles both load directions in a single bearing.
- Separable: easier service than non-separable bearings.
- Standard tapered roller sizing.
- Open: greaseable for re-lubrication.

All About Tapered Roller Bearing
Tapered roller bearings are designed so the inner/outer ring raceway and apex of the tapered rollers intersect at one point on the bearing centerline.
By receiving a combined load from the inner and outer ring, the rollers are pushed against the inner ring rib and are guided by the rib.
Induced force is produced in the axial direction when a radial load is applied, so it must be handled with a pair of bearings.
The inner ring with rollers and outer ring come apart, thus facilitating mounting with clearance or preload.
Assembled clearance is however hard to manage and requires special attention.
Tapered roller bearings are capable of supporting large loads in both the axial and radial directions.
NTN also has a line of case hardened steel bearings designed for longer life.
NTN tapered roller bearings also include bearings with two and four rows of tapered rollers for extra-heavy loads.
