Angular Contact Ball B. FAG 7320 -B-MP

The FAG 7320 -B-MP angular contact ball bearing, with a 100 mm bore and a 40-degree contact angle, accommodates high unilateral axial loads as well as radial forces.

The FAG 7320 -B-MP angular contact ball bearing is a single-row rolling bearing made from standard bearing steel (100Cr6) with dimensions of 100 × 215 × 47 mm. Thanks to the 40-degree contact angle, this design can simultaneously accommodate radial loads and significant axial forces in one direction. The open bearing is suitable for locally lubricated shaft mountings in mechanical and plant engineering.

What is the 7320-B-MP angular contact ball bearing suitable for in mechanical engineering?

This single-row angular contact ball bearing is suitable for bearing arrangements where, in addition to radial forces, high unilateral axial forces are also present. As the axial forces are, by design, only accommodated in one direction, the bearing is often fitted in pairs with a second rolling bearing mounted in the opposite direction.

Thanks to its open design, the bearing can be integrated directly into existing oil or grease circulation systems. The tolerance class P0/PN (ABEC 1) meets the standardised requirements for industrial manufacture and maintenance.

What is the function of the brass cage and the 40-degree contact angle in the 7320 -B-MP angular contact ball bearing?

The solid brass cage (-MP) guides the balls with dimensional stability and low noise, even under vibration. At the same time, the 40-degree contact angle allows for high axial load capacity. For operating conditions involving thermal stress in the range from –20 to +150 degrees, brass offers high strength.

The open bearing has no integrated sealing washers. An external housing seal and a controlled lubricant supply are required to protect the standard radial bearing clearance and the raceways from contamination.
