OEM C3 Precision Spindle Bearings Ceramic Balls HC7001E.T.P4S.UL Characteristics of spindle bearings |
Spindle bearings are single row angular contact ball bearings comprising solid inner and outer rings and ball and cage
assemblies with solid window cages. They cannot be dismantled. The
bearings are available in both open and sealed versions. |
|
Spindle bearings have restricted tolerances. They are particularly suitable for
where requires very high guidance accuracy and speed capacity,
especially for slewing part of the main spindle of machine tool. |
|
Angular contact ball bearings have raceways in the inner and outer rings that are displaced with
respect to each other in the direction of the bearing axis. This
means that they are designed to accommodate combined loads, i.e.
simultaneous radial and axial acting loads. |
|
The axial load carrying capacity of angular contact ball bearings
increases with the enlarging of contact angle. The contact angle α
is defined as the angle between the line joining contact point of
the ball and the raceways in the radial plane, along which the load
is transmitted from one raceway to another, and a line
perpendicular to the bearing axis. |
|
Single row angular contact ball bearings can accommodate axial loads acting in one direction only. Under
radial loads a force acting in the axial direction is engendered in
the bearing, and this force must be counteracted. Consequently the
bearing is normally adjusted via a second bearing. |
|
Single row angular contact ball bearings have one high and one low shoulder. Some bearings, particularly
those of Diameter Series 8 and 9, have an inner ring with two high
shoulders as a deep groove ball bearing. The low shoulder on one or
both rings enables a large number of balls to be filled in the
bearing, thus giving the bearings a relatively high load carrying
capacity. They are of inseparable design. |
|
The contact angle αis 15°(C) or 25°(E), designation suffix C.T.P4S
or E.T.P4S.F, for the most common sizes, the cage is a solid window
type cage made of textile-laminated phenolic resin(T) and the
tolerance class is P4S. Single row angular contact ball bearings
are produced in two versions. |
