WHERE QUALITY COMES FIRST

Carcass Are Identified According To Reinforcement Fiber Type

E

 

Indicates Polyester

P

 

Indicates Nylon

EE

 

Designates a Belt with Polyester Warp and Weft

PP

 

Indicates a Nylon Warp and Weft

EP

 

Is a Carcass with Polyester Warp and Nylon Weft

 

 

 

EE CARCASS

POLYESTER WARP

POLYESTER WEFT

 

This type of belt carcass provides the greatest resistance to belt stretch and shrinkage.

It also affords good troughability and excellent resistance to acid environments.

 

 

 

EP CARCASS

POLYESTER WARP

NYLON WEFT

 

This design offers the low stretch characteristics of polyester combined with the excellent fastener holding and impact resistance of nylon.

 

 

 

PP CARCASS

NYLON WARP

NYLON WEFT

 

This design delivers maximum resistance to impact and damage from material trapped between the belt and the pulley. Excellent fastener holding troughability and flexibility around small pulleys are also afforded by the nylon carcass.

 

 

 

MONOPOLY WITH

PP OR EE

 

This is a special woven structure and there is no peeling of layers or damage done to the belt by penetration; can be driven by small diameter pulley.

Fabric styles are 220, 330, 440, 550 PIW.
