Bearings
We stock SKF and NSK for their unique understanding of rotating equipment and how machine components and industrial processes are interrelated.
SKF spherical roller bearings
Spherical roller bearings are designed to accommodate heavy radial loads, as well as heavy axial loads in both directions. Spherical roller bearings have two rows of rollers, a common sphered outer ring raceway and two inner ring raceways inclined at an angle to the bearing axis. The centre point of the sphere in the outer ring raceway is at the bearing axis, so the bearings are self aligning and not sensitive to any misalignment of the shaft relative to the housing.
SKF CARB bearings
CARB toroidal roller bearings combine the self-aligning capability of spherical roller bearings with the axial displacement ability of cylindrical roller bearings. CARB bearings can also have the compact cross section and high load carrying capacity normally associated with needle roller bearings.
Cylindrical roller bearings
Cylindrical roller bearings are available in many designs, series and sizes. The majority are single row bearings with a cage. High-capacity bearings, double row bearings, multi-row bearings, single, double and multi-row full complement bearings (without a cage) and split bearings complete the standard assortment. Bearings with a cage can accommodate heavy radial loads, rapid accelerations and high speeds. Full complement bearings incorporate a maximum number of rollers and are therefore suitable for very heavy radial loads at moderate speeds. High-capacity cylindrical roller bearings combine the high load carrying capacity of a full complement bearing with the high speed capability of a bearing with a cage.
Self-aligning ball bearings
Self-aligning ball bearings have two rows of balls and a common sphered raceway in the outer ring. The bearings are insensitive to angular misalignment of the shaft relative to the housing. Self-aligning ball bearings generate less friction than any other type of rolling bearing, which enables them to run cooler even at high speeds.
Self-aligning ball bearings are available in several designs, including:
- basic design bearings
- bearings with an extended inner ring
- sealed bearings
Thrust ball bearings
Thrust ball bearings are manufactured as single direction or double direction thrust ball bearings. They are designed to accommodate axial loads only and must not be subjected to any radial load. Thrust ball bearings are separable, i.e. the shaft washer, housing washer(s), ball and cage assembly(s) can be mounted separately. Shaft washers have a ground bore to enable an interference fit. The bore of the housing washer is turned and always larger than the shaft washer bore.
Deep groove ball bearings
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.
Y-bearings (insert bearings)
Y-bearings are based on sealed deep groove ball bearings, 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. Available in easy to use Y-bearing units that are ready-to-mount, greased and sealed, enabling initial errors of alignment to be compensated for. Y-bearing units reduce noise and vibration levels. They have a long life and reduced maintenance cost, with the sealed unit being quick, easy and safe to replace.
Angular contact ball bearings
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. angular contact ball bearings are manufactured in a wide variety of designs and sizes. The most commonly used designs are:
- single row angular contact ball bearings
- double row angular contact ball bearings
- four-point contact ball bearings
Needle roller bearings
Needle roller bearings are bearings with cylindrical rollers that are small in diameter relative to their length. The ends of the rollers are relieved slightly to modify the line contact between the rollers and raceways. This prevents stress peaks at the roller ends to extend bearing service life. In spite of their low cross section, needle roller bearings have a high load carrying capacity. Therefore, they are extremely suitable for bearing arrangements where radial space is limited. Needle roller bearings are available in many different designs, series and in a wide range of sizes, which make them appropriate for a wide variety of operating conditions and applications.
