SKF Single Row Cylindrical Roller Bearings

SKF single row cylindrical roller bearings are high-capacity, radial load bearings that use a single row of cylindrical rollers to provide high stiffness, high load capacity and good speed performance in a relatively compact design. They are one of the most common bearing types in gearboxes, electric motors and general industrial machinery.

What are SKF single row cylindrical roller bearings?

SKF single row cylindrical roller bearings feature cylindrical rolling elements which are in direct linear contact with the raceways. They consist of an outer and an inner race, with a bronze, steel or polyamide cage which houses the cylindrical rollers.

With a high load capacity and the ability to operate at moderate speeds, single row cylindrical roller bearings are amongst the most commonly used bearings across the globe.

Typical uses:

  • Industrial gearboxes and reducers
  • Electric motors and generators
  • Pumps, compressors and fans
  • Heavy process machinery (steel, paper, mining, etc.)
