Description
SKF 32938 is a tapered roller bearing reference, within Bearings. Request a quote for 32938 via WhatsApp or email with the quantity you need; we respond promptly with lead time and equivalents.
The tapered roller bearing has rolling elements and raceways shaped like a truncated cone, which allows it to support radial and axial loads simultaneously in one direction. By design, it is always mounted in opposed pairs or against another bearing, never alone, because a single tapered roller cannot support the shaft without an opposing thrust.
The designation of an SKF tapered roller usually starts with the series number (30000, 31000, 32000 depending on the ratio of diameter to width) followed by the dimension code. It often has a suffix with a letter or a slash with another number, indicating a design or precision variant compared to the standard bearing of the same size.
They are used in gearbox shafts, differentials, machine tool spindles, truck axles and generally in any assembly where the load arrives inclined relative 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 assembly: 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. The assembly requires 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 among manufacturers —SKF, Timken, NTN and FAG use comparable series for the same sizes— but there are more design variants than in a deep groove ball bearing, so it is advisable to confirm the exact equivalent against the complete code, not just the series number.
Send us the complete tapered roller code, including suffixes, and we will confirm the equivalent and whether it needs to be ordered as a pair. MR Accesorios Industriales provides quotes via WhatsApp or email with the manufacturer's part number.

Frequently Asked Questions
- Why are tapered roller bearings sold in pairs?
- Because a single tapered roller bearing cannot support the shaft: it needs a second opposed bearing to provide axial counterbalance. That is why the complete pair is almost always requested.
- How is axial clearance adjusted during mounting?
- With a nut or a calibrated spacer that is adjusted until the clearance specified by the manufacturer is achieved, generally measured with a dial indicator. An incorrect adjustment greatly shortens service life.
- Are there cross-brand equivalents for tapered roller bearings?
- Yes, most standard sizes have equivalents among manufacturers. Send us the complete code, with suffixes, and we will confirm what we have in our system.
