Variable Speed Cog-Belt®

Variable speed cog-belts are designed for use with industrial variable speed pulleys to gain a wide range of driven speeds.

Timken Belts is a leader in variable speed belt technology. Belts are made of Ethylene Propylene Diene Monomer (EPDM) that is durable and resistant to oil, heat, hardening and glazing. EPDM also has a superior flex and load carrying capacity with a broad operating temperature range of -50°F to +250°F.

The Variable Speed Cog-Belt has been engineered to the same high standards that Timken Belts uses to produce belts for original equipment manufacturers (OEMs).
