Mounted ball bearing unit
KOYO
Koyo Ball Bearing Units. having many features. are
available in various types. Select the bearing unit optimal
for your purpose among the types with unique features.
1 Supreme load capacity and accuracy
Koyo Ball Bearings for bearing unit featuring the
internal structure identical to single row deep groove bail
bearings. bear axial load in both directions, as well as
great radial load. The tolerance is equal to that of an
standard bearing. They feature high rotation accuracy
and high speed rotation.
2 Itational self aligning mechanism and optimal fit
Koyo Bail Bearing Units have self aligning mechanism
by the spherical outside surface bearing and the housing
with and spherical bearing seat. Because of this mecha-
nism. déviation of the shaft center caused by warp of the
shaft flexion of axis (shaft) or offset is automatically
adjusted to eliminate abnormal load onto the bearing.
leading to guarantee of original service life of the bear-
ing.
Since the spherical outside surface of the bearing is
ground and the spherical bearing seat of the housing is
machined by a boring machine with high accuracy.
optimal fitting of the bearing and the housing can be
obtained. as well as superior aligning performance.
The allowable aligning angle of standard bail bearing
unit is 3°. while that of bail bearing unit with cover is 1°.
