Heavy Duty Slide Bearings

  • New generation withstands highest loads up to a pin-pressure of 40 N/mm² which is an increase of 100%
  • New heavy duty slide bearings need the same construction space compared to existing slide bearings
  • When operated under typical pin pressures of 20-25 N/mm² the wear rate can be reduced up to about 50% compared to common slide bearings
  • Very good sliding properties with low friction coefficients in dry and wet environment, very good chemical resistance
  • Can be used in the joint and in protection rollers
