Angular Contact Ball B. FAG 7303 -B-XL-TVP-UA

The FAG 7303 -B-XL-TVP-UA angular contact ball bearing, measuring 17 × 47 × 14 mm, accommodates combined radial and single-direction axial loads at a contact angle of 40 degrees.

The FAG 7303 -B-XL-TVP-UA angular contact ball bearing is a single-row radial ball bearing made from standard rolling-element steel (100Cr6) for industrial bearing applications. With a bore of 17 mm, an outside diameter of 47 mm and a width of 14 mm, this rolling bearing accommodates radial forces and axial loads in one direction. The 40-degree contact angle distributes combined forces obliquely to the radial plane via the balls. A polyamide cage guides the rolling element set at operating temperatures ranging from -20 to +120 degrees.

In which installation scenarios does the 7303 -B-XL-TVP-UA angular contact ball bearing absorb forces?

The bearing is designed to support shafts subjected to radial loads simultaneously with axial forces acting on one side only. The design requires a second, oppositely mounted bearing for axial loads acting in opposite directions. As this is an open design without integrated seals, it must be operated within a protected housing with a lubricant supply. External sealing elements in the surrounding structure shield the raceways from particles and retain the lubricant within the housing.

What does the suffix ‘UA’ mean in relation to pairing?

The designation ‘UA’ identifies this rolling bearing as a universal design for installation in sets. When mounted in pairs in an O or X arrangement, a small amount of axial play is created structurally. Both units can be aligned directly against each other without additional shims. The dimensions comply with tolerance class P0 (ABEC 1), whilst the polyamide cage limits the operating temperature to a maximum of +120 degrees.
