Posidyne X-Class clutch brakes (photo) are suitable for incline conveyor applications because they provide precise positioning each cycle. They act as a holding brake so that materials never slide backward on the incline. The clutch brakes feature Oil Shear Technology, which provides a film of transmission fluid between the brake disc and the drive plate. As the fluid is compressed, the fluid molecules in shear transmit torque to the other side. This torque transmission causes the two components to reach the same relative speed. Since most of the work is done by the fluid particles in shear, wear is virtually eliminated. These brakes last up to 10 times longer than standard dry friction brakes and do not need maintenance, adjustment, or disc replacement. — Force Control Industries, Inc., Fairfield, Ohio
