An MRC 7306PJDE-BRZ single-row angular contact ball bearing in the 7306 envelope — 30 mm bore, 72 mm outside diameter, 19 mm width. A single row of balls runs on an offset raceway pair, so the bearing carries radial load together with thrust in one direction. It is used on pump shafts, gearbox input shafts and light spindle positions where the thrust direction is known.
7306 – ISO single-row angular contact ball bearing, 30 mm bore, 72 mm OD, 19 mm width
MRC 7000-series nominal contact angle: 29°
BRZ – machined bronze cage
No clearance suffix in the designation, so internal clearance is normal (CN)
The 29° MRC contact angle sits between the 15° and 40° norms of other schemes, giving a useful thrust share while keeping speed capability higher than a 40° design. A machined bronze cage tolerates higher temperature and marginal lubrication better than a pressed steel cage and resists cage wear under vibration. Because the angle is specific to the MRC scheme, a 7306 from another brand in 15°, 25° or 40° is a different part in the same envelope.
Bore: 30 mm (1.1811 in)
Outside diameter: 72 mm (2.8346 in)
Width: 19 mm (0.7480 in)
Rows: 1
Contact angle: 29°
Cage: machined bronze
Closure: open
Internal clearance: CN
Sold as 1 Pc, single bearing, open on both faces. No grease shield, seal ring or spacer is included.
The bearing is directional. The wide land of the outer ring takes the thrust load, so it faces away from the load. Where two are used to carry thrust in both directions they are set as an opposed pair with the correct axial clamp on the inner rings. Mounting is by press or induction heat onto a clean, burr-free shaft seat; the bronze cage is not a press surface.
Direct interchange is with another 29° single-row angular contact bearing in the 7306 envelope. A 7306B (40°) or 7306C (15°) shares the same 30 x 72 x 19 mm envelope but carries a different thrust split and preload behaviour, so those are related sizes rather than equivalents. MRC became part of SKF, and the MRC number remains the reference marking on this bearing.
