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) Tow inertia rubber elastic couplings are offered to enable quiet operation with torsional elasticity to damp vibration and absorb shock loads. The ES Couplings consists of two close grained cast iron jaws with hard rubber drive elements interposed between them, retained by a reinforced thermoplastic cap. The KE Coupling also has close grained cast iron jaws with a Pebax Polyester elastomeric gear ring interspaced to damp vibration and torsional loads. This series can be provided with taper-bore bushes on the coupling end. The KE Coupling provides a lower cost solution. Except as indicated all dimensions in mm *(I)Running Torque should not exceed 50% of this figure. *(3)Coupling half can be supplied for taper-bush fitted either from hub *(2)Coupling half manufactured with blind bore. end (type H) or from coupling end (type F). *(4)Taper bore versions are shorter.

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 Howdon wedges are coloured coded for identification. Sizes 350SG to 900SG use brass pins as standard (steel optional), other clutches use steel as standard pin material. Number of Wedges in Clutch Note:- Torque capacity of size 250SG controlled by unit size, and not wedge capacity. Sizes 1000SG and above are designed to accept up to four wedges, size 250SG only has two...
