Bearing basics

There are a number of factors that go into the bearing selection process:
  • available space
  • loads (magnitude and direction)
  • misalignment
  • precision and stiffness
  • speeds
  • operating temperature
  • vibration levels
  • contamination levels
  • lubrication type and method
Once a suitable bearing has been selected, there are several other factors that need to be considered:
  • suitable form and design of other components in the arrangement
  • appropriate fits and bearing internal clearance or preload
  • locking devices
  • adequate seals
  • the type and quantity of lubricant
  • mounting and dismounting methods
When designing an application, every decision affects the performance, reliability and economy of the shaft system.
As the leading bearing supplier, SKF manufactures a wide assortment of bearing types, series, designs, variants and sizes. The most common of them are introduced in Bearing types and designs. Others are covered elsewhere in Bearings, units and housings and its sub-sections.
