The recommended PSI for our wide belts is as follows:- 45 – 55 PSI for paper
- 55 – 65 PSI for regular cotton cloth
- 65 – 75 PSI for polyester
Poly belts are occasionally used to plane or dimension metals or wood with a PSI over 70. For these types of operations, this is acceptable. Paper belts should never be used for these types of applications.
