Our Insulate products are designed for maximum durability in electrical machines

  • Ceramic balls create an insulation distance off the full ball diameter - your guarantee against current erosion
  • C3 clearance (C4 on request) allows for the normal thermal expansion of motor- / generator shafts
  • Non-friction rubber seals (Type RZ) protect against outside contamination without compromising low-friction running
  • Well proven wide temperature greases ensure long grease life and silent running


The Corrotec product group is designed for maximum reliability in wet and otherwise challenging conditions in the food, pharma, and beverage industries.

  • Ceramic balls allow for long service life even when lubrication is challenged by water and other contaminants
  • Stainless steel rings allow survival in moist conditions
  • High-quality friction seals offer maximum protection against particle ingress
  • Material and lubricant combinations all live up to FDA / EN 1935 regulations for incidental food contact


CeramicSpeed Xtreme bearings are not optimized against one specific industry but offer an overall more robust solution to several industries. The benefits of combining high-quality steel rings with ceramic balls allow for:

  • Higher rotational speeds
  • Reduced lubrication or even dry running
  • Longer service life in oscillating or start-stop applications
  • Longer service life in contaminated environments
  • Longer service life under extreme temperatures
