Angular Contact Ball B. FAG 7304 -B-XL-TVP

The 7304 -B-XL-TVP angular contact ball bearing, measuring 20 × 52 × 15 mm, accommodates high axial forces on one side as well as radial forces.

The single-row angular contact ball bearing 7304 -B-XL-TVP from FAG Wälzlager is designed for bearing arrangements subject to combined loads. With an inner diameter of 20 mm, an outer diameter of 52 mm and a width of 15 mm, this design complies with tolerance class P0 (ABEC 1). Manufactured from 100Cr6 rolling-bearing steel, this open bearing has a standard radial clearance. As the outer ring and inner ring are manufactured without a flange or groove, the assembly can be fitted precisely into housing bores.

In which applications does the 7304 -B-XL-TVP angular contact ball bearing accommodate axial loads?

This rolling bearing is used where axial forces need to be absorbed specifically in one direction. Due to the contact angle, the rolling elements transmit radial and unilateral axial loads simultaneously. Where required, users can mount single-row angular contact ball bearings in pairs in an O or X arrangement, or in opposition to a second bearing, to counteract axial forces in the shaft system. In the open design, lubrication is supplied via the surrounding housing.

What characteristics do the 40-degree contact angle and the polyamide cage offer?

The 40-degree contact angle gives this design a high axial load-carrying capacity in one direction. The guided polyamide cage (TVP) keeps the weight low and contributes to quiet running. When designing the system, the permissible temperature range of –20 to +120 degrees Celsius must be taken into account, as this is determined by the plastic cage. As the bearing remains unsealed, external seals protect the raceways from the ingress of dirt and moisture.
