Mitsuboshi Ribstar EPDM belt is a v-ribbed belt that has excellent weather (cold resistant) and ozone resistance, and uses eco-friendly EPDM rubber. Thanks to its EPDM base (synthetic rubber), it is also extremely temperature-resistant.

Mitsuboshi Ribstar EPDM PK Series belts are low friction loss belt for automotive accessory drive systems. Friction loss due to bending and deformation of the belt is reduced by suppressing the internal heat generation of the belt rib, and succeeds in improving the transmission efficiency of the belt; we were able to lower fuel consumption with the auxiliary belt alone. Mitsuboshi Ribstar EPDM Belt is used in broad range of automotive engine accessory drive from light weight cars to trucks and buses. Because the belt thickness is thin it is excellent at bending resistance, it is used with small pulley diameters, and can be used in reverse bending layout with back side pulley.

Mitsuboshi Belting promotes the manufacture of products that lower environmental impact by conserving energy and reducing waste. UMS Transmission also offer special specification Mitsuboshi RIBSTAR belt products that match different engine characteristics.
