CONVEYOR ROLLERS

Assignment

The equipment is used as part of roller conveyors of mechanized technological lines for applying external protective coatings to pipes with a diameter of up to 1420 mm.

Constructive execution

The roller is a solid rubber-coated bandage tire pressed onto the hub rim.

The transmission of torque to the roller from the drive reducer is carried out through the shaft, which has a keyed connection with the bushing and is fixed on the bearing supports.

Distinctive features

Unlike similar imported equipment, the rollers produced by Uralshina LLC are serviceable and maintainable.

There is a possibility of multiple replacement of the bandage tire upon reaching the critical wear values of the rubber mass without replacing other structural elements, which is achieved by the execution of the “shaft-hub” and “rim-massive tire” assemblies in a collapsible version.

Specifications

It is possible to complete it with a rubber mass with physical and mechanical parameters adapted to the technological features of the customer’s operation, subject to the fundamental technical feasibility of its manufacture.
