Y-bearings, which are usually referred to as insert bearings, are based on sealed deep groove ball bearings in the 62 and 63 series, but have a convex outer ring and in most cases an extended inner ring with a certain locking device enabling quick and easy mounting onto the shaft.
- Designed for quick, easy and safe mounting
- Sealed, greased and ready to mount
- Multiple sealing solutions available
- Virtually maintenance-free variants available
- Available in different designs, materials and sizes
- Standard and food grade greases available
- In accordance with ISO
Y-bearings with grub screws
Y-bearings with grub (set) screws in the inner ring are locked onto the shaft by tightening the two cup point hexagonal grub screws, positioned 120° apart. These bearings are suitable for applications for both constant and alternating direction of rotation.
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, the extended inner ring of the bearing has an eccentric step. The step accommodates the locking collar.
SKF ConCentra Y-bearings
SKF ConCentra Y-bearings have an inner ring symmetrically extended on both sides. The patented SKF ConCentra locking technology is based on the expansion and contraction of two mating surfaces: the bearing bore and the external surface of the stepped sleeve.
Y-bearings with a tapered bore
Y-bearings with a tapered bore have an inner ring symmetrically extended on both sides and a tapered bore (taper 1:12) enabling them to be mounted on a standard H 23 series adapter sleeve. Mounting onto an adapter sleeve enables the bearings to run smoothly and the full limiting speed can be achieved, even when using commercial grade shafts.
Y-bearings with a standard inner ring
Y-bearings with a standard inner ring have normal tolerances for the bearing bore diameter and are locked onto the shaft using an appropriate interference fit.
