SKF bearing units typically consist of a bearing, seal, lubricant and shaft locking mechanism. The units are preassembled and adjusted at the factory. These ready to mount units are available with either ball or roller bearings.
In addition to standard all steel units, SKF has more focused standard products – which target a particular industry – like the food, beverage and pharmaceutical industries where, for example, special materials, lubricants, seals and housings are needed.
To accommodate the high performance characteristics of SKF bearings, SKF designs and manufactures a full line of bearing housings and housing seals. These housings and seals are well known for their quality and durability. In addition to their unique design features, which simplify mounting, alignment and relubrication, SKF housings are precision machined so that the incorporated bearing can realize its full service life.
Seals have a crucial impact on system performance. Life and reliability of what is often considered a simple component can make all the difference to your products and operations.
SKF has more than 100 years of experience in various industries and applications, and is the only company that can support key aspects of the sealing system through its knowledge of bearings, seals, lubrication and associated science and technology. SKF offers expert advice and provides support throughout the life cycle of your sealing system.

Rolling bearings generally comprise two bearing rings with integral raceways. Rolling elements are arranged between the rings and roll on the raceways. Rolling elements can be balls, cylindrical rollers, needle rollers, tapered rollers or barrel rollers.
The rolling elements are generally guided by a cage that keeps them at a uniform distance from each other and prevents them coming into contact with each other. In needle roller bearings and ribless spherical roller bearings, the cage also ensures that the rolling element axis is positioned correctly.
The function of plain bearing arrangements, like rolling bearing arrangements, is to support or guide parts that are movable relative to each other. They must support and transmit the forces occurring in this case.
Whereas the bearing arrangement elements in rolling bearing arrangements are separated from each other by means of rolling parts – rolling elements – the movable component in plain bearing arrangements – normally a shaft, stud or strip – slides on the sliding surface of a static bearing bush, bearing cup or sliding strip.
