Heinrich Brothers, Inc. will help you find a Conveyor Roller or Conveyor Pulley to meet your conveying needs. We supply replacement rollers and replacement pulleys to fit most brands of conveyors.

Custom types and custom sizes of rollers are
also readily available. Whether you require a roller for
a powered conveyor or a gravity conveyor, we can help.

Bearings

• Non-Precision
  - A full ball complement in a stamped metal body
  - Zinc plated for better corrosion resistance
  - Recommended for light loads and slow speeds
  - Not intended for quiet operation
  - Very cost effective
• Semi-Precision
  - Made of machined steel with tighter tolerances than non-precision bearings
  - Includes a ball retainer to keep the balls separated and evenly spaced 
  - Capable of higher speeds and higher load capacities than non-precision bearings
  - Available in stainless steel
• ABEC Precision
  - Made from high quality, heat treated steel and ground to a micro finish with tolerances much tighter than semi-precision bearings
  - Capable of even higher speeds and higher loads than semi-precision bearings
  - Sensitive to axle deflection which may limit load capacity in long rollers
  - Recommended for quiet operations
  - Many styles available including polypropylene housed, insert, agricultural, Framesavers, and more
• Bushings
  - Solid pieces of material with no moving parts
  - Materials include UHMW, Hardwood, Teflon, Nylon and more 
  - Recommended for use in extreme temperatures, dirty environments, corrosive environments, or sanitary conditions depending on the material
• Plastic Bearings
  - Stainless steel balls in a molded plastic body
  - Recommended for highly corrosive environments or underwater
  - No lubrication required
