Thrust ball bearings, double direction, sphered housing washers
Double direction thrust ball bearings consist of one shaft washer, two housing washers and two ball
and cage thrust assemblies. The bearings are separable so that mounting is simple. The various parts can be
mounted separately. The housing washers and ball and cage thrust assemblies are identical to those of the
single direction bearings.
Smaller bearings are available with either a flat seat surface on the housing washers or with a sphered seat
surface. Bearings with sphered housing washers can be used together with sphered seat washers to compensate
for misalignment between the housing and shaft. The sphered seat washers are available from SKF, but must be
ordered separately.
Double direction thrust ball bearings can accommodate axial loads acting in both directions and can
thus serve to axially locate a shaft in both directions. They must not be subjected to radial load.
