Angular contact ball bearings have raceways in the inner and outer rings that are displaced relative to each other in the direction of the bearing axis. This means that they are designed to accommodate combined loads, i.e. simultaneously acting radial and axial loads.
Single row angular contact ball bearings
SKF single row angular contact ball bearings can accommodate axial loads in one direction only. A single row bearing is typically adjusted against a second bearing.

Double row angular contact ball bearings
SKF double row angular contact ball bearings correspond in design to two single row angular contact ball bearings arranged back-to-back, but take up less axial space.

Four-point contact ball bearings
Four-point contact ball bearings are radial single row angular contact ball bearings with raceways that are designed to support axial loads in both directions.

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.
Product features
- 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.

Deep groove ball bearings are particularly versatile. They are simple in design, non-separable, suitable for high and very high speeds and are robust in operation, requiring little maintenance. Because deep groove ball bearings are the most widely used bearing type, they are available from SKF in many designs, variants and sizes. Deep groove ball bearings for special applications include:
- sensor bearing units
- High temperature bearings and bearing units
- bearings with Solid Oil
- INSOCOAT bearings
- hybrid bearings
- NoWear coated bearings
- polymer ball bearings
Single row deep groove ball bearings
have deep, uninterrupted raceway grooves. These raceway grooves have a close osculation with the balls, enabling the bearings to accommodate radial loads and axial loads in both directions.

Stainless steel deep groove ball bearings
SKF stainless steel deep groove ball bearings are corrosion resistant when exposed to moisture and several other media. They can accommodate radial loads and axial loads in both directions. These bearings have a lower load carrying capacity than same-sized bearings made of high chromium steel.

Single row deep groove ball bearings with filling slots
Single row deep groove ball bearings with filling slots have a filling slot in both the inner and outer rings to accommodate more balls than standard deep groove ball bearings. Filling slot bearings have a higher radial load carrying capacity than bearings without filling slots, but their axial load carrying capacity is limited. They are also unable to operate at the same high speeds as bearings without filling slots.
