• Engine

  Phenolic resin idler pulleys:

  • A special phenol resin is being used which is more durable compared to conventional nylon based material.
  • These bearings are contributing to a weight and cost reduction.

  Heat resistance bearings for alternators:

  • Expanded flaking resistance countermeasure technology under vibrating conditions and very high temperatures (180 degrees Celsius)
  • Superior heat-proof performance by the use of special raceway material, retainers, seals and heat treatment.

  Ceramic ball bearings for turbochargers:

  • Rolling bearings with ceramic balls are contributing to an improved turbocharger performance

  Low-friction roller follower for rocker arms:

  • Reduced friction by the adjustment in contact with the surface.

  Split type needle roller and cage assemblies for big ends of motorcycle connecting rods:

  • Suitable for severe lubrication conditions e.g. in two-cycle engines etc.
  • Is contributing to a reduction of output loss.
