These units have split bearings, housings and seals. A gasket between chair
and cap prevents oil leakage at this point. The split seals at each end grip and
rotate with the shaft and prevent any escape of oil along the shaft.
Provision is made in the cap to enable the gunmetal bearings to be correctly
adjusted in the housing seating
The oil level gauge and drain plug are fitted as standard and can be fitted on
the opposite side to the illustration at extra cost.
Special collars can be fitted inside the housings to take up thrust. These are
not split and have to be arranged on the shaft before fitting the bearings. The
chamfer on these collars must be away from the bearing face.
Suitable for high speeds · Designed for fans and similar applications. Quiet in
operation · Compensate for misalignment occurring after erection · Oil level
gauge fitted as SHAFT LIMITS
The bearings are accurately bored to BS4500: Section 1.1:1990 ISO 2861:1988, E8
limits. For general use standard bright mild steel shafts or turned shafting to
h8 limits can be used.
For more selective uses where high loads and speeds are required the shaft
journals should have a ground or lapped finish and the clearance between the
journal and bearing diameter should be 0.0015in for each inch of diameter
(0.0015mm for each mm of diameter).
