Decoding TIMKEN 7304 B
- 73Series
- Angular contact ball bearings, 73 series. Series differ in outside diameter and width even when the bore is the same.
- 04Bore
- Bore 20 mm (04 × 5).
- BSuffix
- TIMKEN suffix: identifies the variant, such as seals or shields, cage, internal clearance or other features.
7304 is the standard ISO basic designation, which sets the bearing type, series and bore.
Description

When a shaft has to handle radial and axial forces at the same time, angular contact ball bearings are often the answer. The TIMKEN 7200 B series is built for that duty, with a 40° contact angle that suits machine tool spindles, pumps, compressors, gearboxes and similar equipment. MR Industrial Accessories supplies these bearings as part of its bearing range for plants and workshops in the United States and Latin America.
Reading the part number helps you order the right size. The 72 prefix identifies an angular contact ball bearing of the 7200 series, and the B suffix tells you the contact angle is 40° and indicates the cage design. The digits that follow the prefix reflect the bore: 7200 B, 7201 B, 7202 B, 7203 B, 7204 B, 7205 B, 7206 B and 7207 B go from smaller to larger bore diameters. That makes it easy to spot the main dimensions from the code alone.
Typical installations include machine tool spindles where rigidity matters, centrifugal and positive displacement pumps that see axial load, screw and reciprocating compressors, gearboxes and gear cases, and electric motors working under demanding conditions. You will also find them in power transmission equipment such as industrial fans and conveyors. Because they take combined loads, they help keep the shaft stable as operating conditions change.
Selection comes down to load size and direction, rotation speed and the surrounding environment. These bearings are sensitive to misalignment, so mounting needs precise alignment. They are usually installed in pairs, either back-to-back, face-to-face or tandem, to set the correct preload and share the load. Grease or oil lubrication can be used depending on the application, and keeping the bearing clean is essential. In dusty or humid areas, consider sealed or shielded versions for extra protection.
For replacement, other brands that follow the same international nomenclature can be used if the dimensions and contact angle match. Tolerances and internal clearance can differ from one manufacturer to another, so it pays to check them. The safest approach is to share the complete original part number with a specialist before installing. Our team can review the data and suggest a suitable equivalent.

Frequently asked questions
- TIMKEN 7304 B bearing: what are its dimensions?
- TIMKEN 7304 B measures 20 mm across the bore and 52 mm across the outside diameter; its width is 15 mm (20 x 52 x 15 mm). Those are the boundary dimensions standardized in ISO 15 for basic designation 7304.
- What does the B suffix mean in TIMKEN 7200 series bearings?
- The B indicates a 40° contact angle, which allows the bearing to carry axial loads in one direction. Keep that characteristic in mind when replacing it so the assembly performs as expected.
- How are angular contact bearings mounted?
- They are typically mounted in pairs, in back-to-back, face-to-face or tandem arrangement, to achieve the required preload and rigidity. Precise alignment and correct lubrication are critical for reliable operation.
- Can I replace a TIMKEN 7200 B bearing with another brand?
- Yes, if the other brand offers the same dimensions and contact angle. Check tolerances and internal clearance before installing. Send us the part number and we can advise on a suitable alternative.
