Industrial CL41290-1LH Formsprag Clutch Assembly

The CL41290-1LH is a Formsprag Clutch FSR-8 sprag clutch assembly designed for backstopping, indexing, and overrunning, delivering 450 ft-lb of torque with a left-hand rotation. This sleeve-bearing supported design uses a 1 in bore and measures 3-1/4 in in outside diameter with an overall length of 3.56 in, and it is oil-lubricated for reliable life in demanding applications. It features Formchrome sprags and supports a maximum speed of 1650 rpm on the inner race and 600 rpm on the outer race, making it suitable for high-load conveyor drives, indexing mechanisms, and other machinery where positive reverse stopping is required. The unit is compatible with vertical (zero-U) mounting configurations and is part of the FSR-8 series, offering a compact, robust solution for industrial overrunning and backstopping needs.
