Textured Round Belting

The textured surface improves gripping ability. Good for light duty conveying and power-transmission applications, this belting is chemical and abrasion resistant and creates stronger connections than hollow-core belting. Join the ends with round belt connectors (sold separately) or use a welding kit.

Textured Round Belts

Outer

Circumference

Often used with lathes and conveyors, these textured belts grip better than standard round belts, making sure heavy loads don’t slip. The solid core makes these belts strong and durable, and they stretch less than hollow core belts. Made from polyurethane, they hold up to chemicals and abrasion. Also known as O-ring and endless belts, they come ready to use.
