It has the characteristics of flat belt soft, V-belt friction, smooth transmission than V-belt, small profile size, high transmission efficiency (92% ~ 97%). When transmitting the same power, its structural width is 50% smaller than that of ordinary V-belt transmission. Multiple wedges transmit high power We are the world's top supplier of V-belts. Our main products are pk belt, V-ribbed belts, automotive timing belts, industrial timing belts, V-belts, toothed belts, etc. Please tell us your needs and we will give you the best service. PK belt advantages >Excellent flexibility >High transmission efficiency >Low noise >Power transmission belt with multiple longitudinal ribs >Torque is transmitted through the contact of the side of the belt rib and the groove of the pulley >Compared with V-belts, it has a larger contact surface area pk belt Features >High grade engineered rubber >Longer service life >Temperature range from -50â?? to +120â?? >Oil, heat,ozone and abrasion resistant >Reduce the space required by the drive system
