| 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:
- Type of oil
- Approximate quantity of surface oil or oil content
- Detail of previously used belt
- Detail of working environment and the temperature involved.

** The thickness of the conveyor belt must be appropriately selected depending on the conveying
materials and the operating environment. This will help extending the service life of the conveyor
belt. |
