Wheel Hub Bearings

Automotive bearings are the foundation of automotive transmission components and are known as the "joints of the automotive industry". They are used to support tire speeds and have a significant impact on vehicle performance. In automobiles, wheel hub bearings are a very important component that can withstand both axial and radial loads. The traditional bearings for car wheels are composed of two sets of tapered roller bearings or ball bearings, which are difficult to assemble, costly, and have poor reliability in automobile factories. The hub bearing unit, on the other hand, combines two sets of bearings as one unit, which has the advantages of good assembly performance, omitted clearance adjustment, light weight, compact structure, and large load capacity. It has been widely used in sedans and is also gradually expanding its application in heavy-duty vehicles.

Skf Insocoat Bearings

SKF high temperature bearings and bearing units are designed to deliver increased reliability, reduced complexity and decreased environmental impact in operating temperatures up to 350 °C (660 °F), making these products very suitable for applications in kiln trucks, roller hearth furnaces, and bakeries. Because SKF high temperature bearings correspond to the ISO dimensions of grease-lubricated bearings, production efficiencies and cost savings can be realized with a simple change to the SKF bearing solution.

Withdrawal Sleeves

Withdrawal sleeves can be used to mount bearings with a tapered bore onto the cylindrical seat of stepped shafts. The sleeve is pressed into the bore of the bearing inner ring, which abuts a shaft shoulder or similar fixed component. The sleeve is located on the shaft by a nut or an end plate. KM or HM lock nuts (Lock nuts requiring a keyway) with appropriate locking devices are suitable. Lock nuts are not supplied with the sleeve and must be ordered separately.

Lock Nuts

Lock nuts are used to locate bearings onto a shaft. Additionally, they can be used to mount bearings with a tapered bore onto tapered shaft seats and adapter sleeves, and to dismount bearings from withdrawal sleeves. Lock nuts are also frequently used to secure gears, belt pulleys and other machine components.

Lock nuts have to be secured to prevent unintentional loosening by:

A locking device that engages a keyway in the shaft or *key slot in the adapter sleeve,
* Or a locking mechanism integrated in the nut.

SKF lock nuts provide a variety of ways to secure the nut onto a shaft. The lock nuts listed here constitute the basic SKF assortment. Lock nuts with other locking methods can be supplied on request. For additional information, contact SKF.

industrial lock nuts:
*Requiring a keyway
*With integral locking

precision lock nuts :
*With integral locking

Lock nuts with integral locking reduce the cost of the shaft as no keyway is required. Installation is quicker and easier because no separate locking device is necessary. However, the loosening torque of these lock nuts requires more attention. For information on loosening torque, refer to the product data sections for the various lock nut series

Self-Aligning Ball Bearings

Self-aligning ball bearings have two rows of balls, a common sphered raceway in the outer ring and two deep uninterrupted raceway grooves in the inner ring. They are available open or sealed. The bearings are insensitive to angular misalignment of the shaft relative to the housing (fig. 1), which can be caused, for example, by shaft deflection.

Double Direction Trust 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.

In addition to the bearings presented in this section, SKF supplies thrust ball bearings for special application requirements. This assortment includes bearings with Solid Oil and NoWear coated bearings.

Single Direction 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.

In addition to the bearings presented in this section, SKF supplies thrust ball bearings for special application requirements. This assortment includes bearings with Solid Oil and NoWear coated bearings.

Angular Contact Thrust Ball Bearings

Angular contact thrust ball bearings are separable, i.e. the washers and ball and cage assemblies can be mounted independently of each other. Although originally designed to support the rotary tables of drilling rigs, they are also suitable for other applications.

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. For a given axial load, a limited radial load can also be supported (Load ratio). The bearings are separable, i.e. the outer ring with ball and cage assembly can be mounted separately from the two inner ring halves.
Both inner ring halves of four-point contact ball bearings have a recessed shoulder. This improves oil flow when the bearing is used in combination with an cylindrical roller bearing (fig. 1). In addition, these recesses can be used to facilitate dismounting.

Double Row Angular Contact Ball Bearings

Angular contact ball bearings have inner and outer ring raceways that are displaced relative to each other in the direction of the bearing axis. This means that these bearings are designed to accommodate combined loads, i.e. simultaneously acting radial and axial loads.
The axial load carrying capacity of angular contact ball bearings increases as the contact angle increases. The contact angle is defined as the angle between the line joining the points of contact of the ball and the raceways in the radial plane, along which the combined load is transmitted from one raceway to another, and a line perpendicular to the bearing axis
The design of double row angular contact ball bearings corresponds to two single row angular contact ball bearings arranged back-to-back.

Single Row Angular Contact Ball Bearings

single row angular contact ball bearings can accommodate axial loads in one direction only. This type of bearing is typically adjusted against a second bearing. Their bearing rings have an upper and a lower shoulder and are non-separable.

Thin Section Bearings

Thin section bearings are designed to save weight, use less space, reduce friction, increase design flexibility and provide high running accuracy.
