SKF ball bearings come in a wide variety of types, designs, series, sizes, variants and materials. Depending on the bearing design, SKF ball bearings are available in four performance classes.
SKF Standard
Standard SKF ball bearings have long been known for their superior quality and long service life. However some applications must accommodate higher loads while reducing friction, heat and wear in the bearing. For these applications, SKF Explorer bearings are the obvious choice.
SKF Explorer
The SKF Explorer performance class of ball bearings is in response to the ever-demanding performance requirements of modern machinery. SKF Explorer ball bearings realized this substantial improvement in performance by optimizing the internal geometry and surface finish of all contact surfaces, redesigning the cage, combining the extremely clean and homogenous steel with a unique heat treatment and improving the quality and consistency of the balls.
SKF Energy Efficient
SKF Energy Efficient (E2) bearings are ideal for light-to-normal load applications, where there is a need to improve reliability, decrease lubricant consumption and reduce energy consumption. Ball bearings within this performance class are characterized by a frictional moment in the bearing that is at least 30% lower when compared to a same-sized SKF Explorer bearing. The bearings realized the substantial reduction of the frictional moment by optimizing the internal geometry of the bearing, redesigning the cage and applying a new, low-friction grease.
SKF Super-precision
SKF super-precision bearings are used in high-speed, precision applications like machine tools, centrifuges, and printing presses, where high speeds, running accuracy and long service life are critical operational parameters.

As a complement to our bearings SKF supplies a wide assortment of bearing accessories like adapter sleeves, withdrawal sleeves and lock nuts.
Adapter and withdrawal sleeves are used to locate bearings with tapered bore on plain or stepped shafts. They facilitate bearing mounting and dismounting and, in many cases, simplify bearing arrangement design.
Lock nuts are used to locate bearings and other components onto a shaft or adapter sleeve and facilitate mounting and dismounting. SKF supplies a wide assortment of lock nuts. SKF lock nuts are easy to install, do not damage the shaft and provide effective locking.
Since seals and bearing housings are in separate sections, the accessories covered in this section include the sleeves and lock nuts used to locate and lock bearings in position on a shaft.

SKF track runner bearings
|
|
|
|
|
|
|
Track runner bearings are designed to run on all types of tracks and to be used in cam drives, conveyor systems, etc. These bearings have a thick-walled outer ring, which enables them to accommodate high radial loads, while reducing distortion and bending stresses.
The outer ring running surface is crowned as standard. This is beneficial for applications where angular misalignment relative to the track may occur or where edge stresses need to be minimized. With the exception of single row cam rollers, track runner bearings are also available with a cylindrical (flat) outer ring running surface.
SKF supplies track runner bearings greased, sealed and ready to mount.
SKF supplies track runner bearings in many different types and designs, and for a wide variety of operating conditions and applications.

SKF super-precision bearings
|
|
|
|
Machine tools and other precision applications require superior bearing performance. Extended speed capability, a high degree of running accuracy, high system rigidity, low heat generation, as well as low noise and vibration levels are just some of the challenges.
Rolling bearings for general industrial applications can only partly fulfill these requirements. Therefore, SKF manufactures a comprehensive assortment of super-precision bearings.
SKF super-precision bearings help original equipment manufacturers and end users to further optimize performance parameters of their equipment and applications. The benefits differ depending on the bearing series and applications but include high speed and load carrying ability, long bearing service life, long maintenance intervals and low energy consumption.
Typical applications for super-precision bearings are:
metal cutting and woodworking machinery spindles
other machine spindles (e.g. balancing machines)
high speed rolling mills
printing machinery
precision ball screws
live centres
high speed turbochargers
vacuum pumps
racing cars
boat gyrostabilizers
machine components for the semiconductor industry

SKF plain bearings
|
|
|
|
|
|
|
Many applications require spherical bearings that are suitable for oscillating movements and that can accommodate misalignment. Rolling bearings only partly fulfil these requirements as they are generally designed for continuous rotation and can only accommodate limited misalignment. Therefore, SKF manufactures spherical plain bearings, rod ends and bushings to provide an economical solution to these challenges.
SKF Spherical plain bearings, rod ends and bushings are produced in various designs and with different sliding contact surface combinations. Each design and combination has characteristic properties which makes it particularly suitable for certain applications.

SKF bearing units
|
|
|
|
 
|
|
|
|
SKF provides different types of bearing units that are ready-to-mount bearing units, which are greased and sealed, and are able to compensate for misalignment of the shaft with respect of the housing.

SKF bearing housings
|
|
|
|
|
|
|
An SKF Bearing housing, together with appropriate SKF bearings constitute economic, interchangeable bearing units that meet the demand for designs that are easy to maintain.
As a leading supplier of rolling bearings, SKF also produces bearing housings in a wide range of designs and sizes that are based on experience collected in all industrial areas. Among others, SKF bearing housings have the following advantages
large assortment of design and sizes
high quality of bearing housings design and manufacturing
worldwide availability
