Rubber Timing Belts

In many cases, custom made belt solutions from BCA start with a Rubber Synchronous Belt as a substrate. These belts, which provide the basis for accurate positioning and placement in product handling applications, are stocked in sleeve form and slit to the necessary width to meet the specific needs of your application. Customization for actual product handling includes covers and machined modifications.

BCA’s technical support team can assist in making the right decisions for your specific needs. With over 200 years of collective belt knowledge and experience within our sales and inside sales organization, we have the answers you need.

Pitches & Heights

Our rubber timing belts are manufactured with Chlorprene rubber and offer oil, heat, and ozone resistance, along with long life wear and tooth shear resistance. Additionally, the tooth side is encased with nylon, which offers wear resistance and low noise benefits. Fibreglass cords impart high tensile strength and dimensional stability.

Optimize Belt Performance

with Custom Modifications

For synchronous or non-synchronous product handling applications, modifications can make a difference in conveying. By changing the construction, material, or finish of the belt, manufacturers can better meet their unique requirements.
