Decoding FAG 30348
- 303Series
- Tapered roller bearings, 303 series. Series differ in outside diameter and width even when the bore is the same.
- 48Bore
- Bore 240 mm (48 × 5).
30348 is the standard ISO basic designation, which sets the bearing type, series and bore.

FAG tapered roller bearings are built to carry radial and axial loads at the same time. Their tapered raceways and rollers spread force across the assembly, which suits tough drivetrain positions. We supply this line to customers in the US and Latin America, and we help you match the part number to the job. Send the number on WhatsApp or by email and the team will get back to you with a quote and any equivalent options.
Reading the designation helps you order the right bearing. Take 302/32, 303/28 or 329/22: the leading digits set the diameter series and contact angle, while the digits after the slash give the bore. Codes like 30336 or 332/32 use the series to define width proportions and load capacity. If a code is unclear, the team can walk you through it.
These bearings show up in gearboxes, conveyors, mills, pumps, fans and earthmoving equipment, as well as road and port machinery and oilseed processing. Because they take combined loads, they fit assemblies where the shaft sees radial and axial force at the same time, which is common in power transmission and support rollers.
Selection comes down to load type, speed and the environment. Seals or shields keep contaminants out, so in dusty or damp areas choose a protected variant. Lubrication has to match the working temperature, and mounting calls for precise alignment and correct axial clearance, since these bearings often run in pairs. A controlled interference fit and a clean seat help the bearing last.
Tapered roller bearings are made to international standards, so codes can be interchanged between manufacturers when dimensions and tolerances line up. A similar number is not enough: check the contact angle, total width and internal design. For a replacement, send the full part number and mounting dimensions so we can suggest the correct alternative.

Frequently asked questions
- What does the code of a FAG tapered roller bearing mean?
- The code mixes numbers for the dimensional series and bore with letters for design variants. In 302/32, the number after the slash refers to the bore. Send the complete part number and we will help you read it.
- How do I know if a tapered roller bearing fits my application?
- Check radial and axial load, speed, temperature and environment. Sealing, lubrication and axial clearance matter. Send the equipment data and current part number and we can guide the selection.
- Can FAG bearings be replaced by other brands?
- Yes, when dimensions and tolerances match international standards. Contact angle and internal design still need checking. For a safe replacement, send the part number and mounting dimensions.
