Y-bearings with an Eccentric 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 the bearing onto the shaft. A single grub (set) 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 extended inner ring on one side and are fitted with the rugged “Superagriseal” on both sides. The eccentric collar is zinc-coated. The outer ring has two lubrication holes as standard.

Y-bearing in YET 2 series

Y-bearings in the YEL 2 series have an extended inner ring on both sides. This reduces the extent to which the inner ring can tilt on the shaft, which allows the bearing to run more smoothly. These bearings are fitted with the rugged “Superagriseal”, and one of the following flinger options

Y-bearing in YEL 2 series

• plain sheet steel flingers, designation suffix 2F
• rubberized sheet steel flingers (multiple seal), designation suffix 2RF.

The outer ring has two lubrication holes as a 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 diameter
• inch shafts from 1/2 to 2 15/16 inch diameter.
