HX series

HX series idlers are available with “open” or “2RS factory-sealed” deep-groove ball bearings for CEMA D and CEMA E applications:

  • HX-30 idler incorporates a 6306 (30 mm) bearing that exceeds CEMA D specifications
  • HX-40 idler incorporates a 6308 (40 mm) bearing that exceeds CEMA E specifications

The HX series idlers feature the following:

  • Patented, engineered shaft reduces overall roll weight and increases performance
  • Patented retaining sleeve creates a smooth contact surface for the rotating lip seal
  • Back seal that allows for a larger grease reservoir for “open” bearing rolls
  • Flinger to employ natural centrifugal forces generated by a rotating idler roll, redirecting potential contaminants away from the bearing cavity
  • Triple labyrinth seal to retard lateral movement and provide a barrier to contaminants reaching the bearing
  • Counter-bored shell with protected weld
  • Lip seal designed to provide added protection for the bearing

Our HX series idlers are available in the following configurations:

  • Troughing
  • Troughing training
  • V returns
  • Return rolls
  • Transition idlers

Both idlers are available in a wide range of application-specific bearing and seal designs, and are paired with a heavy-duty frame design (incorporating die-formed end brackets) for maximum rigidity. 

H-Plus series (regreasable)

The H-Plus series idler is a heavy-duty, regreasable precision idler that meets CEMA D requirements.

The H-Plus series idlers feature the following:

  • Up to 1 3/8” engineered shaft (reduced to ¾” at bearing) is available for additional load capacity on all return rolls and all 42” belt width and wider troughing rolls
