Decoding SKF 30202
- 302Series
- Tapered roller bearings, 302 series. Series differ in outside diameter and width even when the bore is the same.
- 02Bore
- Bore 15 mm: by standard, 02 designates 15 mm.
30202 is the standard ISO basic designation, which sets the bearing type, series and bore.

Tapered roller bearings from SKF are designed with truncated cone-shaped rolling elements and raceways, enabling them to handle both radial and axial loads in one direction. They must always be installed in pairs facing each other or against another bearing, as a single bearing cannot support the shaft without opposing thrust.
The part number for an SKF tapered roller bearing typically begins with a series number that reflects the diameter-to-width ratio, followed by a dimension code. A suffix—often a letter or a slash with another number—denotes a design or precision variant compared to the standard bearing of the same size.
These bearings are found in gearbox shafts, differentials, machine tool spindles, truck axles, and other assemblies where loads act at an angle to the shaft, combining radial and axial forces. They are usually mounted in pairs, one at each end of the shaft, and adjusted with a nut to set the axial clearance.
Setting the axial clearance is the most critical step during installation: if a tapered roller bearing is too tight, it will overheat and fail within hours; if too loose, the shaft will play and the raceways will wear prematurely. Follow the manufacturer's procedure, typically using a torque wrench or dial indicator to measure the final clearance.
While tapered roller bearing numbering is fairly standardized by metric size across manufacturers—SKF, Timken, NTN, and FAG offer comparable series for the same dimensions—there are more design variants than with deep groove ball bearings. Therefore, always confirm the exact equivalent using the full part number, not just the series number.
Provide the complete part number of your tapered roller bearing, including any suffixes, and we will confirm the available equivalent and whether it needs to be ordered as a pair. MR Industrial Accessories quotes via WhatsApp or email with the manufacturer's part number.

Frequently asked questions
- Why are tapered roller bearings sold in pairs?
- A single tapered roller bearing cannot support the shaft on its own; it requires 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 during mounting?
- Using a nut or calibrated spacer, adjusted until the clearance specified by the manufacturer is reached, generally measured with a dial indicator. Incorrect adjustment greatly shortens service life.
- Are there equivalences between brands for tapered roller bearings?
- Yes, most standard dimensions have an equivalent across manufacturers. Send us the full part number, including suffixes, and we will confirm which option corresponds.
