Contact A-Type
Thin Section Ball Bearings
In applications
with high axial loads the A-Type, angular contact ball bearing should
be used. This bearing also works well in radial or combined radial-thrust
applications. The A-Type bearing should never be used alone to support
moment loads or reversing axial loading.
Two A-Type bearings
are often used as a duplex pair. The three different configurations
for duplex bearings are discussed in the Engineering Data section.
Radial
Contact C-Type
Thin Section Ball Bearings
The C-Type, radial
contact ball bearing is designed with deep ball grooves to withstand
high loads. Although this bearing is used primarily in applications
with radial loads, it can withstand moderate axial loads, reversing
axial loads, and moment loads.
4-Point
Contact X-Type
Thin Section Ball Bearings
The X-Type, or 4-point
contact, ball bearing is ideal for moment loading. X-Type bearings are
designed with gothic arch raceways creating 4 contact points between
the balls and the raceways. This design is excellent for moment loading
and reversing axial loading. The X-Type bearing can be used for other
light loading conditions, but is not recommended in place of the C-
or A-Type bearing for pure radial loads.
