Bearing Features:

1. Single row angular contact design
The inner and outer raceways are offset, creating a defined contact angle that allows the 7303B bearing to simultaneously carry radial loads and significant axial load in one direction—ideal for applications with combined loading.

2. Defined contact angle (B-type)
The offset raceways generate a relatively large contact angle (B designation typically indicates 40 ° contact angle), which increases the 7303 B bearing’s capacity to sustain axial load in its designed direction and improves resistance to thrust-induced deflection.

3. High radial load capability
The robust ball set and solid ring construction allow the bearing to carry substantial radial forces, making it suitable for shafts subjected to both steady and varying radial loads.

4. Strong unidirectional axial load support
The contact angle focuses load transmission along a path that efficiently carries axial force in one direction; this makes the 7303-B-XL-TVP bearings well suited for arrangements where thrust is predictable and predominantly one-way.
