NSK Bearings

• Ball bearings
  

  
  NSK, founded in 1916, was the pioneer producer of ball bearings in Japan. Now NSK has the largest market share of bearings in Japan and is one of the largest bearing manufacturers in the world extremely contributing to the growth and advancement of mechanical technology.
• Roller bearings
  

  
  In bearings of this type, the cylindrical rollers are in linear contact with the raceways. They have a high radial load capacity and are suitable for high speeds.
• Bearing units
  

  
  The NSK bearing unit is a combination of a radial ball bearing, seal, and a housing of high-grade cast iron or pressed steel, which comes in various shapes. The outer surface of the bearing and the internal surface of the housing are spherical, so that the unit is self-aligning. The inside construction of the ball bearing for the unit is such that steel balls and retainers of the same type as in series 62 and 63 of the deep groove ball bearing are used. A duplex seal consisting of a combination of an oil-proof synthetic rubber seal and a slinger is provided on both sides.
