Jaw In-Shear Type Couplings

The Jaw In-Shear Coupling is non-fail safe, and therefore the coupling acts as a fuse to avoid equipment damage in case of torque overloads. Rather than the spider becoming compressed among the interlocked jaws of every hub, our In-Shear coupling gets the hubs drawn aside with the jaws aligned axially. The wider spider can be after that in a shear-plane.

The Jaw In-Shear Spider is radially removable, and therefore neither hub (or driver/driven equipment) needs to be moved to create replacements of the Spider. This saves money and time in maintenance costs. The retaining band which encloses the In-Shear Spider offers six little pins which basically slide across a groove the perimeter of the Spider and twist-lock into place. You won’t work its method loose and since there are no fasteners involved, the maintenance and removal of the Spider takes only a few minutes. EP In-Shear Spider is used with our industry-standard L-Type and C-Type Jaw Coupling hubs which provides another added convenience – no need to stock different hubs just for this new design of elastomer. Existing applications using in-compression spiders can simply be retrofitted with the new In-Shear Spider if the features are beneficial. The Jaw In-Shear Spider is made from a tough Urethane formula which provides the best combination of durability, chemical resistance, temperature range, and torsional softness. The hubs it is used with go up to a maximum bore of 4. 00” (102mm).

Common applications for the EP Jaw In-Shear Coupling include: electric motors to centrifugal pumps, fans, blowers, gear boxes, and plastic extruding machinery. It solves many maintenance problems in industries like pulp & paper, petrochemical, mining and steel.
