How to read SKF 32305
- 323Series
- Tapered roller bearings, 323 series. For the same bore, each series has a different outside diameter and width.
- 05Bore
- 25 mm bore: 05 × 5.
32305 is the standard (ISO) basic designation: it defines the type, the series and the bore.
Description
The SKF 32305 bearing has a 25 mm bore, a 62 mm outside diameter and a 25.25 mm total width (25 x 62 x 25.25 mm).

The tapered roller bearing has rolling elements and raceways shaped like a truncated cone, which allows it to support radial and axial load at the same time in a single direction. By design, it is always mounted in pairs facing each other or against another bearing, never alone, because a single tapered roller does not support the shaft without opposing thrust.
The designation of an SKF tapered roller usually starts with the series number (depending on the ratio between diameter and width) followed by the dimension code. It often carries a suffix with a letter or a slash with another number, which indicates a design or precision variant with respect to the standard bearing of the same dimension.
They are used on gearbox shafts, differentials, machine tool spindles, truck axles and in general in any assembly where the load arrives at an angle to the shaft, combining radial and axial thrust. They are commonly found in pairs, one at each end of the shaft, adjusted with a nut that regulates the axial clearance of the assembly.
Adjusting the axial clearance is the most delicate part of the mounting: a tapered roller that is too tight heats up and is destroyed in hours, and one that is too loose lets the shaft play and wears the raceways prematurely. Mounting calls for following the manufacturer's procedure, generally with a torque wrench or a dial indicator to measure the final clearance.
Tapered roller numbering is fairly standardized by metric size across manufacturers — SKF, Timken, NTN and FAG use comparable series for the same dimensions — but there are more design variants than in a deep groove ball bearing, so it is advisable to confirm the exact equivalent against the full part number, not just the series number.
Send us the full part number of the tapered roller, suffixes included, and we will confirm the available equivalent and whether it needs to be ordered as a pair. MR Accesorios Industriales quotes via WhatsApp or email with the manufacturer's part number.

Frequently Asked Questions
- What are the dimensions of the SKF 32305 bearing?
- The SKF 32305 bearing has a 25 mm bore, a 62 mm outside diameter and a 25.25 mm total width (25 x 62 x 25.25 mm). These are the standardised boundary dimensions (ISO 355) of the basic designation 32305.
- Why are tapered rollers sold in pairs?
- Because a single tapered roller cannot support the shaft: it needs a second bearing facing it to provide axial counterbalance. That is why the complete pair is almost always requested.
- How is the axial clearance adjusted when mounting them?
- With a nut or a calibrated spacer that is adjusted until the clearance specified by the manufacturer is reached, generally measured with a dial indicator. An incorrect adjustment greatly shortens service life.
- Are there equivalences between brands for tapered rollers?
- Yes, most standard dimensions have an equivalent across manufacturers. Send us the full part number, with suffixes, and we will confirm which option corresponds.
