Decoding TIMKEN 32310B
- 323Series
- Tapered roller bearings, 323 series. Series differ in outside diameter and width even when the bore is the same.
- 10Bore
- Bore 50 mm (10 × 5).
- BSuffix
- TIMKEN suffix: identifies the variant, such as seals or shields, cage, internal clearance or other features.
32310 is the standard ISO basic designation, which sets the bearing type, series and bore.
Description
TIMKEN 32310B measures 50 mm across the bore and 110 mm across the outside diameter; its total width is 42.25 mm (50 x 110 x 42.25 mm).

When a shaft carries radial and axial force at the same time, a tapered roller bearing is often the answer. The tapered rollers and raceways make line contact, which spreads the load across the assembly and gives the bearing high capacity for the forces involved. You will find this design in gearboxes, wheel axles and agricultural machinery, where loads are heavy and alignment is controlled. MR Industrial Accessories supplies the TIMKEN line.
Reading the designation tells you a lot before you open a catalog. Take 32205B: the leading digits point to the size, and the trailing B signals a construction variant. Change the number and the dimensions change with it, as happens across 32308B, 32309B and 32310B. The B commonly reflects a different contact angle or an internal design change, so the full part number is what identifies the exact bearing.
These bearings show up in automotive, agricultural, mining and metallurgical work. In this market they are common in seeders, harvesters, trailers, conveyor belts and machine tools, and they also appear in earthmoving equipment and power transmission systems. The reason is the same everywhere: they handle radial and axial forces on the same shaft.
Selection comes down to sealing type, internal clearance and lubrication. Tapered rollers normally run in pairs with preload adjustment, which makes alignment and mounting practice critical. Grease or oil both work, depending on speed and operating temperature. Good sealing keeps contamination out and helps the bearing last. Follow the manufacturer's recommendations for each application.
Interchange between brands is possible when dimensions and design line up. TIMKEN is a global reference, and other manufacturers offer alternatives. To substitute safely, compare the complete part number and the technical specifications rather than the size alone. Our team can review the details with you.

Frequently asked questions
- TIMKEN 32310B bearing: what are its dimensions?
- TIMKEN 32310B measures 50 mm across the bore and 110 mm across the outside diameter; its total width is 42.25 mm (50 x 110 x 42.25 mm). Those are the boundary dimensions standardized in ISO 355 for basic designation 32310.
- What does the letter B mean in the designation?
- It marks a construction variant inside the series, such as a different contact angle or an internal modification. Keep the complete part number intact when you compare bearings.
- How are tapered roller bearings mounted?
- Usually in pairs, with preload set through nuts, washers or spacers. Alignment and lubrication need to be right for the bearing to run as intended.
- Can I replace a TIMKEN bearing with another brand?
- Yes, when dimensions and design are equivalent. Compare the full part number and the technical specifications, and ask us to confirm the match.
