Angular Contact Ball B. FAG 7309 -B-XL-TVP-UA

FAG single-row angular contact ball bearing 7309 -B-XL-TVP-UA with a 45 mm bore, 40° contact angle and a polyamide cage for high unilateral axial loads.

The 7309 -B-XL-TVP-UA angular contact ball bearing from FAG is a single-row rolling bearing made from standard bearing steel (100Cr6) with a bore of 45 mm, an outer diameter of 100 mm and a width of 25 mm. The design features raceways set at an angle to one another with a contact angle of 40 degrees. This enables the unit to accommodate radial forces as well as single-sided axial forces. Manufactured to tolerance class P0 (ABEC 1) and with standard radial clearance, this open bearing provides a dimensionally accurate basis for industrial bearing arrangements.

What is the 7309 -B-XL-TVP-UA angular contact ball bearing suitable for?

Design engineers use this design when combined forces from the radial and single-sided axial directions need to be supported. The 40-degree contact angle enables the bearing to accommodate axial forces in a defined load direction. Typical applications include shaft mountings with a single-sided guiding load. As no sealing washers are fitted, the component is suitable for bearing arrangements where lubrication is supplied via an external system. The permissible temperature range is from –20 to +120 degrees Celsius.

What special feature does the UA version offer in terms of pairing?

The suffix ‘UA’ denotes a universally combinable bearing design. If the bearings are fitted in pairs in an O or X arrangement, this results in a defined, low axial clearance within the bearing set. This simplifies assembly, as the bearing clearance does not need to be adjusted manually using shims. The integrated polyamide cage guides the rolling elements and reduces the weight of the rotating parts. When designing the housing, care must be taken to ensure external sealing to prevent the ingress of contaminants.
