Detailed Product Description
Self-aligning ball bearings with an extended inner ring are
designed for less demanding applications using commercial grade
shafting. The special bore tolerance enables easy mounting and
dismounting.
Self-aligning ball bearings with an extended inner ring are
axially located on the shaft by means of a pin or shouldered screw,
which engages in a slot at one side of the inner ring and also
prevents the inner ring from turning on the shaft.
When two self-aligning ball bearings with an extended inner ring
are used to support a shaft, they should be positioned so that the
inner ring slots either face each other, or are at the outboard
positions of the bearings. If this is not the case, the shaft is
axially located in one direction only.
Permissible speeds
The permissible operating speeds for self-aligning ball bearings
with an extended inner ring depend less on the common criteria like
heat generation or cage stability and strength, but are more
influenced by the manner in which the bearings are located on the
shaft. Therefore, the product table contains only limiting speeds
valid for location on shafts according to h8 tolerances.
