Product Description

We are mine belt conveyor steel roller, belt conveyor steel rolls, heavy Conveyor Idler Pulley Factory from china

The steel rollers are made under the process of initial turning, static balancing, welding&assembly, fine turning, grinding and dynamic balancing etc. Usually the roller has critical requirements on the roundness, straightness, runout, con-centricity and cylindricity - that's why final precision grinding process is a must for a qualified steel roller.

To get mirror-like finishing, we use 3M special polishing material for polishing after fine grinding process.

Dynamic balancing is also a must for high speed working roller.
