Decoding FAG 32303-A
- 323Series
- Tapered roller bearings, 323 series. Series differ in outside diameter and width even when the bore is the same.
- 03Bore
- Bore 17 mm: by standard, 03 designates 17 mm.
- ASuffix
- FAG suffix: identifies the variant, such as seals or shields, cage, internal clearance or other features.
32303 is the standard ISO basic designation, which sets the bearing type, series and bore.
Description
FAG 32303-A measures 17 mm across the bore and 47 mm across the outside diameter; its total width is 20.25 mm (17 x 47 x 20.25 mm).

Tapered roller bearings in the FAG -A series are built for applications where radial and axial forces act at the same time. The angled raceways create a linear contact pattern that supports heavy loads and adds rigidity to the assembly. You will find them in gearboxes, speed reducers, wheel hubs and machine tools, where running accuracy and long service matter. MR Industrial Accessories supplies this line as one of the brands in its catalog.
Codes in this series include 30304-A, 30305-A, 30307-A, 30308-A, 30309-A, 30313-A, 30314-A and 30315-A. Reading the number: the leading digits define the bearing type and the dimension series, while the -A suffix points to an internal variation, often a revised roller or cage design. Bore, outer diameter and width follow from the code, so having the full designation makes selection straightforward. If the marking is worn or unclear, our team can help you decode the nomenclature.
These bearings show up across many industries. Typical installations include agricultural gearboxes, conveyors, flour mills, mining equipment and cement plants, as well as wheel hubs on commercial vehicles, road machinery and railway equipment. Because they take radial and axial loads together, they suit reducers and power transmission systems where both force directions are present.
When choosing a bearing, look at load size and direction, operating speed and the surrounding environment. Fitting calls for accurate alignment and correct axial clearance, usually set with nuts or shims. Lubrication can be grease or oil depending on the application, and a lubricant with EP additives is a common choice for high loads. Sealing should match the site: in dirty conditions, effective seals keep particles out. Follow the manufacturer's instructions for mounting and startup.
On interchangeability, tapered roller bearings from different brands can often be swapped when the main dimensions and series design line up. Tolerances and internal clearance can differ between makers, so check them. For a replacement, the safest route is to send the complete code engraved on the old bearing. We can review compatibility and suggest suitable alternatives.

Frequently asked questions
- FAG 32303-A bearing: what are its dimensions?
- FAG 32303-A measures 17 mm across the bore and 47 mm across the outside diameter; its total width is 20.25 mm (17 x 47 x 20.25 mm). Those are the boundary dimensions standardized in ISO 355 for basic designation 32303.
- What does the -A suffix mean in these bearings?
- The -A suffix marks a design variant within the series, which may involve changes to the cage, rollers or surface treatment. For the exact characteristics of a specific code, contact us on WhatsApp.
- How do I choose the right tapered roller bearing?
- You need the radial and axial loads, speed, available space and environmental conditions. With that information we can recommend the correct code. Write to us on WhatsApp and we will advise you.
- Do FAG bearings have equivalences with other brands?
- In general they can be interchanged with bearings from other brands that share the same dimensions and series design. Always verify tolerances and internal clearance. Consult us about compatibility for your application.
