Sheargard Overload Clutches The design of the Sheargard Clutches provides for the transmission of high torques (up to 92,195 lb-ft) with a compact, low inertia unit. Standard stock products enables prompt delivery, at low cost of shearpin chain sprockets and flexible shaft couplings. The provision of an optional motor monitor plate enables disconnection of the power supply and / or operation of alarm signals in the event of an overload when used in conjunction with a limit switch or proximity switch. In the diagram Hub “A” and Flange “B” have matching tapered slots cut axially in their periphery,...

Sheargard Overload Clutches Standard Stock Sheargard Clutches are available in five sizes providing a torque range from 20 to 5,013 Ib-ft. Other units with torque ratings to 92,200 lb-ft are available to order, on short lead time. For further details contact Cross & Morse Sales Office. Dimensions Clutch Size Clutch Size *(1)For standard Torque Ratings see table page 12. *(2)The drive sprocket/pulley can overhang spigot. *(3)Dimensions E & F can be adjusted to suit sprocket widths. *(4)W37, W50, & W75 Brass Std, others steel.

Chain Coupling Dimensions Sheargard Flexible Couplings Sheargard Chain Couplings The standard Cross Sheargard unit combines with the Chain Coupling to provide stock overload couplings with minimum backlash and a high reliability. This construction provides a simple, reliable, easy to assemble flexible coupling capable of transmitting high loads and accommodating shaft misalignment with continuous overload protection. Motor monitor assemblies can also be used to switch off power in the event of an overload. Sheargard ES & KE Couplings For high speed drives (over 500 rpm) low inertia rubber elastic...

Sheargard Torque RatingsSelection of Wedges for Torque Rating For each size of Sheargard clutch a selection of Standard wedge pins are available, which can be combined together to provide the desired torque setting. Standard wedges are coded for identification. Sizes 350SG to 900SG use brass pins as standard (steel optional), other clutches use steel as standard pin material. A representative selection of standard torque settings possible with standard wedges is shown in the table below, all torque ratings being accurate within ±10%. Additional torque settings can be provided with standard or...
