Apache guide discs are extremely versatile and can perform in bi-directional or uni-directional applications. To meet your unique requirements, simply order custom dimensions, durometer or material composition of the discs.
As with all of Apache products, the Series M disc was specifically developed to perform, efficiently and reliably. To enhance durability, it’s made from Reliathane, Apache’s special blend of wear-resistant polyurethane.
To enhance disc life, guide discs are available with a variety of wear-resistant additives. In fact, Apache developed a proprietary chemical resistant urethane to help protect against conditions, such as hydrogen sulphide, encountered in severe environments.
