The SKF PER.30203-T belongs to the PER.…-T line of single-row tapered roller bearings. Its tapered rollers and angled raceways make it a fit for arrangements that carry radial and axial loads at the same time while keeping the shaft well located. Typical uses include gearboxes, reducers, wheel axles and other industrial machinery where motion has to be controlled precisely.
Reading the code helps you order the right replacement. PER tells you it is a single-row tapered roller bearing; the digits that follow, 30203 in this case, set the size and dimension series; and the -T suffix means the rings received a special heat treatment for higher operating temperatures, depending on the series. Quote the complete designation so the bearing you receive matches the one on the machine.
In service, these bearings appear in speed reducer gearboxes, drive shafts, road and earthmoving machinery, pumps, industrial fans and conveyor rollers. Automotive work also uses them in wheel hubs and differentials, and food processing equipment relies on them as well. Their combined-load capacity suits assemblies that need the shaft to turn with rigidity and precision under tough conditions.
Selection comes down to the radial and axial loads the position will see, the rotation speed and the surrounding environment. Check the sealing arrangement: dusty or damp locations call for labyrinth seals or extra oil seals. Mounting demands careful alignment and correct axial clearance, set with shims or lock nuts. Grease or oil works as lubricant depending on the application, and it must be renewed on schedule to prevent premature wear. Poor mounting shortens bearing life.
SKF tapered roller bearings are built to international dimension standards, so equivalents from other makers with the same specifications can often be used. Even so, confirm the full code and tolerances; contact angle or heat treatment differences can change how the bearing performs. Ask our team whenever compatibility with the original part is in question.

Frequently asked questions
- What does the -T mean in PER.30203-T?
- The -T suffix identifies a special heat treatment that lets the bearing run at higher temperatures than a standard version. This suits applications where friction or the environment generates heat, such as reducer gearboxes or motors. Check the data sheet for the exact temperature range.
- When should I use a tapered roller bearing instead of a ball bearing?
- Tapered roller bearings handle combined radial and axial loads far above what ball bearings can take, but they are not meant for very high speeds. Choose tapered for high load capacity and rigidity; choose ball bearings for high speed with moderate loads.
- Can SKF tapered roller bearings be replaced by other brands?
- They follow international dimension standards, so other brands meeting the same specifications can be interchanged. Always verify the complete code and tolerances, because heat treatment or contact angle differences may affect performance.
