2311/2321 Series

Steel Single/Double Sprocket Roller

Product Features:
  • Welding the steel sprocket to the steel tube gives it the capacity to transmit high torque and meet the requirements for heavy duty transportation.
  • The precision ball bearing is pressed tightly into the steel bearing housing for maximum durability.
  • The environmental working conditions are broad. They can be used in both high and low temperature applications.
  • The covering on the outside of the sprocket protects the bearings by providing excellent resistance to dust.
  • Temperature range: -20°C – +80°C.
