Formsprag Fan Backstops

Formsprag engineers specifically designed the economical, low-torque LCB Series backstop to prevent problems associated with windmilling in fan applications. The Model LCB-200 and 400 are economical low torque clutches which can accommodate a range of shaft diameters between 1-7/8" and 5".

These clutches can be installed on vertical or horizontal fan shafts without the use of a key. The backstops feature a compact, maintenance free, easy-to install design requiring only 1.125" of shaft engagement. Units have a wide operating temperature range of -13 to 194° F (-25 to 90° C), which was important for very hot and very cold applications. All LCB models are lubricated for life and self-actuated with no power or utility required to operate.
