Key Features

• Standard 6" and 7" diameter rolls have .250" wall thickness.
• Standard 4" and 5" diameter rolls have .150" wall thickness. The option is available to have .250" wall thickness.
• Shaft is hollow above 13" roll length.
• Hollow shafts are stronger than solid shafts. This results in less shaft deflection as well as reduced weight.
• Plugs are machined for interference fit inside bearing diameter. This reduces risk of bearing distortion from oversize fit and excessive play in under-sizing.
• Plugs are internally threaded to accept specialty shaft ends.
• Shaft ends can be made to fit any frame dimension or slot size.
• Bearing housing is machined to;
      a) Ensure quality of outside bearing housing diameter.
      b) Ensure concentric fit with can.
• Can is bored to accept housing and continuous welded at interior of can edge, eliminating any possibility of belt contact and wear. This also improves the T.I.R. (straightness) of the roll.
• Depth of bearing housing allows for extensive seal arrangement, including a rear seal.
• Seal channel design allows for pressure greasing of complete cavity.
• This product line is available in steel, rubber, urethane, HDPE or ceramic coated rolls.
• Progressively widening gaps in our end brackets aid in the prevention of material entrapment.
• Rigid angled foot straps help to eliminate bending and twisting for improved frame alignment. Allows frames to be tilted to aid in belt tracking.
