HC series
The HC series idlers are produced using proprietary manufacturing techniques that allow adjustment of the bearing end-play setting to precise engineered specifications, providing absolute consistency roll to roll.
The 3/4” modified geometry automotive-class tapered roller bearing idler roll features an advanced five-stage seal design that contributes to long-life operation without re-lubrication:
- An exterior shield provides an initial barrier to divert contaminants away from bearing cavity.
- A flinger employs natural centrifugal forces to redirect potential contaminants away from the bearing cavity.
- A grease-filled labyrinth seal retards lateral movement of contaminants.
- A contact lip seal provides additional sealing protection and keeps lubricant in the bearing cavity.
- A rear seal provides added protection for the grease reservoir.
The HC series idlers feature the following:
- Counter-bored roll shell, protected weld
- Available in sealed only
Our HC series idlers are available in the following configurations:
- Troughing
- V-return
- Troughing training
- Return training
H-Plus series (regreasable)
The H-Plus series idler is a heavy-duty, regreasable idler.
The H-Plus series idlers feature the following:
- Adjusting nut: provides additional protection to seal area and establishes a very precise bearing adjustment
- Extra-heavy die-formed bracket: designed with super-wide base and direct mounting to end angle
- Inverted angle base: self-cleaning design helps eliminate roll and belt damage from material buildup
Additional H-Plus series idler features include:
- Combination lip and labyrinth seal: unique, precision die-cast nut and triple horizontal labyrinth seal provide three baffles to keep contaminants out. The lip seal contacts the precision zinc die-cast surface to provide maximum seal integrity.
- Modified geometry tapered roller bearings: provide more bearing contact area than ball bearings, spreading the load over a larger area to relieve stress and enhance bearing life under heavy loads and impact.
Our H-Plus idlers are available in the following configurations:
- Troughing
- Troughing training
- Return rolls
- Rubber disc return roll
- Return training
