SKF announces the development of a sealed single row angular contact ball bearing suitable for applications in many industries where reliability, long service life and reduced life cycle costs are essential.

  • For use in applications ranging from pumps and compressors to gearboxes, elevators and electric motors  
  • Features two non-contact steel reinforced NBR (Nitrile Butadiene Rubber) seals, and a high performance, long lasting polyurea (GXN) grease as standard
  • Dimensionally interchangeable with, and have the same high load carrying capability, as open bearings
  • Non-contact seal lip design forms narrow gap between seal lip and its counterface on bearing inner ring to exclude contaminants and retain grease, even in applications with vertical shafts 
  • Does not generate frictional heat due to non-contacting design, which enables operation at same high speeds as open bearings
  • Cooler operating temperatures help extend service life of the lubricant
  • Comparison tests indicate operation with 30% lower peak temperatures and 20% lower steady-state temperatures than same-size bearings with contact seals (values based on degrees Celsius) 
  • 72 Series range from 15 to 55 mm bore while the 73 Series range from 12 to 50 mm bore
  • Available as non-matchable bearings for single use, and can also be offered as universally matchable bearings in three clearance and preload classes
