Our Conveyor Belt
Rubber Grade: Oil Resistance
In some working conditions where conveying materials that involve oil and/or heat transfer, normal conveyor belt cannot be used. Because the oil will destroy or deform the cover rubber into unusable shape. In this condition, the Oil Resistance grade rubber conveyor belt must be used instead.
  Grade: OR1
 
 
For conveying oil coated materials
For conveying parts or materials coated with oil. The different type of oil can have different
effect on the belt and shorten the life of the conveyor belt. Additional information must be
provided when ordering the Oil Resistance Grade conveyor belt:
  1. Type of oil
  2. Approximate quantity of surface oil or oil content
  3. Detail of previously used belt
  4. Detail of working environment and the temperature involved.
   
  Grade: OR2
 
 

For conveying oily materials in high temperature environment
In the working environment where there is high temperature involved, the use of OR2 grade will help extending the life of the belt. If you are not sure which one to choose, we can help determing the appropriate grade. Please contact us for more information.
