Phenolic Cotton Cloth Laminated Tube

 

Production Description

Phenolic Cotton Cloth Laminated Tube is a 3126 laminated product made of cotton cloth impregnated with phenolic resin and baked by hot rolling. It has high radial tensile strength.

 

Application

Phenolic Cotton Cloth Laminated Tube can be used as a cage for high-speed bearings.

 

Instructions

1) After the laminated pipe is processed, it is easy to absorb moisture. It is best to dip-coated insulating paint for moisture-proof treatment.

2) Store in the original package in a dry, cool, ventilated room or under a shed that is strictly forbidden to smoke or fire. The storage period is twelve months from the date of leaving the factory.
