Analysis of Rubber Coated Roller

1. Regular Rubber Coating Types

When choosing rubber， you need to consider chemical resistance, wearing resistance, and antistatic properties. Different equipment has different requirements for rubber, such as printing equipment care more about ink reaction.

There are various rubber types that you can choose, such as EPDM (Ethylene-Propylene-Diene Monomer); PU (Polyurethane); Silicone Rubber; NBR (Buna Nitrile); SBR (Styrene-Butadiene Rubber latex); CR (Neoprene), etc.

Specific dynamic balancerequirements are related to

the working speed of equipment

Runout

Runout is one of the standards toevaluate the geometrical tolerance

such as roller cylindricity. Usually,

the finished product’s runout is

between 0.02mm to 0.05mm.
