Angular Contact Ball B. FAG 7321 -B-MP
The FAG 7321 -B-MP angular contact ball bearing, with a 105 mm bore, brass cage and a 40-degree contact angle, offers high axial load-carrying capacity in one direction.
The 7321 -B-MP angular contact ball bearing is a single-row rolling bearing designed for combined radial and single-direction axial loads. Manufactured from standard rolling bearing steel 100Cr6, this FAG bearing is characterised by its open design and its main dimensions: a 105 mm bore, a 225 mm outer diameter and a 49 mm width. Thanks to its standard radial clearance and tolerance class P0 (ABEC 1), this component is suitable for demanding assemblies with defined concentricity requirements.
What are the industrial applications for the 7321 -B-MP angular contact ball bearing?
The 7321 -B-MP angular contact ball bearing is primarily used where high axial forces in one direction act in conjunction with radial forces. Thanks to its nominal contact angle of 40 degrees, the bearing effectively absorbs axial loads. Typical applications include industrial drives and mounted shafts with combined load profiles. As this is the standard open design, the bearing is usually fitted in pairs or in a face-to-face arrangement with a second bearing. Lubrication is provided by the unit’s respective lubrication system.
What are the advantages of the brass cage in the 7321-B-MP angular contact ball bearing?
The suffix ‘MP’ denotes a solid brass cage that guides the rolling elements precisely. Brass is characterised by dimensional stability and favourable friction properties. This cage design is rated for operating temperatures between –20 and +150 degrees Celsius. Due to the open design without an integrated seal, on-site sealing must be provided to prevent the ingress of dirt and the loss of lubricant. The lubricant requirements must be factored in accordingly for maintenance and relubrication.
What are the dimensions of the 7321 -B-MP angular contact ball bearing?
This angular contact ball bearing has an inner diameter of 105 mm, an outer diameter of 225 mm and a total width of 49 mm. It is a single-row bearing made from 100Cr6 rolling-bearing steel, with an open design and no flange or ring groove on the outer ring. It is manufactured to the standard tolerance class P0 or ABEC 1.
What does the specification of a 40-degree pressure angle mean?
The contact angle describes the inclination of the line of action between the contact points of the balls and the raceways relative to the radial plane. In the B version, with a contact angle of 40 degrees, higher unilateral axial forces can be accommodated than in bearings with a smaller angle. The load is transmitted through the rings at an angle to the bearing axis.
What is the clearance of the 7321 -B-MP angular contact ball bearing?
The model is designed with standard radial bearing clearance. In the case of single-row angular contact ball bearings, the actual operating clearance or the desired preload is only established during assembly, when the bearing is positioned axially against a second bearing. The standard bearing clearance is suitable for standard fit conditions on the shaft and housing.
Why does this angular contact ball bearing not have an integrated seal?
As an open roller bearing, this design does not require abiding or non-contact sealing discs. This allows the bearing to be lubricated directly via the oil or grease system of the parent assembly. From a design perspective, care must be taken to ensure that external seals protect the interior of the bearing housing from contaminants and moisture.
What is the temperature range for which the 7321 -B-MP angular contact ball bearing is designed?
The permissible operating temperature range is from -20 to +150 degrees Celsius. Both the roller bearing steel and the solid brass cage are designed for this temperature range. When designing the lubrication system, lubricants should be selected whose viscosity and thermal stability are suited to these operating limits.
Can the bearing be fitted individually or only as part of a set?
The 7321 -B-MP angular contact ball bearing is designed in its standard version for single-bearing arrangements. As a single-row angular contact ball bearing can only accommodate axial forces in one direction, the design usually requires a mating bearing on the opposite side to guide the shaft in the opposite direction.
