Maintenance free bearings: bearings produced from Hadfield manganese steel, X 120 Mn 12 deep work- hardened by special technique on the bearing surface to provide remarkable resistance to abrasive wear.

Surface characteristics: the bearing surface has a cross-hatched surface preferentially oriented in the direction of bearing rotation. It is produced by mechanical work hardening of the surface having high resistance to abrasive wear. This cross-hatched surface allows a good distribution of the applied lubricant and can trap abrasive particles.

Conditions of use:

  • MAXIMUM PRESSURE
    Up to 100 N/ mm²
    (contact pressure calculation based on projected surface)
    Above 100 N/ mm² (36 psi) : consult us
  • OPERATING SPEED
    From 0 to 30 m/ min.
    (0 to 90 ft/ min.)
    Above this, consult us
  • LUBRICATION
    All oils and greases are suitable; however greases loaded with graphite, metallic or copper compounds are not recommended. This type of bearing can function without applied lubrication even in very abrasive conditions. Greasing on initial set- up is imperative
  • BEARING COMBINATIONS:
    Shaft adapted to the maintenance free bearings technology, surface hardned shafts up to 60 HRc
    We can supply these pins and shafts
  • LIMITS OF USE:
    Limits of use are governed by speed and pressure.
    Preliminary testing is necessary for utilisation above these limits.
