Y-bearings

Y-bearings with an eccentric Fig. 9
locking collar
Y-bearings with an eccentric locking collar are
intended primarily for use in applications where
the direction of rotation is constant. On one
side of the bearing inner ring is an eccentric
extension that fits the locking collar. Turning the
locking collar on the inner ring extension in the
direction of rotation locks the collar and bearing
on the shaft. A single grub screw further secures
the collar to the shaft. There are two standard
series available from SKF.
Y-bearings in the YET 2 series have an extend-
ed inner ring on one side and are fitted with the
rugged standard integral seal († fig. 9). The
eccentric collar is coated (zinc-coated for bearings
with a metric bore, black oxidized for bearings
with an inch bore). The outer ring has two lubri- Fig. 10
cation holes as standard.
Y-bearings in the YEL 2 series have an
extended inner ring on both sides († fig. 10).
This reduces the extent to which the inner ring
can tilt on the shaft, which enables the bearing
to run more smoothly. These bearings are fitted
with the rugged standard integral seal and one
of the following flinger options:
• plain sheet steel flingers, designation suffix 2F
• rubberized sheet steel flingers (multiple seal),
designation suffix 2RF/VL065
The outer ring has two lubrication holes as
standard.
Bearings without lubrication holes can be
supplied on request. They are identified by the
suffix W.
The SKF range comprises bearings for metric
shafts from 15 to 60 mm and inch shafts from
1 /2 to 2 7 /16 inch († product table on pages 98
to 101).
