This single row angular contact ball bearing carries a 140.0 mm bore, 300.0 mm outside diameter and 62.0 mm width, with a net mass of 20.5 kg. It is fitted with a solid brass cage (MP), giving stable ball guidance under axial and combined loading. Limiting speed is rated at 3350.0 1/min, with a reference speed of 2400.0 1/min. The 40° contact angle design of the 7328-B-MP-UB bearing allows it to take up high axial loads in one direction combined with radial loads, and it is commonly mounted in pairs for load in both directions. The solid brass cage provides strength and dimensional stability at the stated speed range, while the single row arrangement keeps radial section low for the given bore size. As an open bearing, it requires external sealing and a lubrication supply matched to the reference and limiting speed values given above.
