Single row angular contact ball bearings are designed especially to carry

combination radial and single direction thrust loads. To carry thrust loads from

opposing directions, these bearings are frequently mounted in duplex pairs

with the contact angles opposed.

Angular Contact Bearing can be mounted in a variety of ways, for example

“back to back” and “face to face”, as illustrated below.

Bearings are also available with universal flush ground side surfaces of the

inner and outer rings for duplex mountings. Flush ground bearings are available

in different preloads to give axial rigidity. Angular Contact Bearing are offered in

extra light, light, and medium series. Each series is available in 15, 25, and 40

contact angles to fulfill a wide variety of applications. A higher contact angle

increases thrust capacity and axial rigidity, but reduces radial capacity and radial

rigidity. Pressed steel, machined bronze, and phenolic cages are available

to meet a variety of speed and duty requirements.
