  • Belongs to the Tough Technology™ Series.
  • Special heat treatment process.
  • High strength inner and outer rings.
  • Higher resistance to cracks.

Product Benefits:

  • Greater resistance to hoop stress.
  • Reduced fracturing of bearing inner rings.
  • Reduced downtime and maintenance costs.
  • Longer life – service life is more than twice that of conventional bearings operating under contaminated conditions.
  • Greater dimensional stability under high temperatures (to 200°C).
