The Lovejoy Jaw In-Shear Coupling is non-fail safe. The coupling acts as a fuse to prevent equipment damage in the event of torque overloads. Instead of the spider being compressed in between the interlocked jaws of each hub, the Lovejoy Jaw In-Shear Coupling has the hubs drawn apart with the jaws aligned axially. The wider spider is then in a shear-plane.

Features of the Lovejoy Jaw In-Shear Coupling include:

  • 2° angular misalignment capability
  • .030” - .047” parallel misalignment capability
  • 50D shore Urethane material — max. temperature of 200°F (93°C)
  • Torsional wind-up of 5° at full load
  • Retaining ring is made from #347 cast stainless steel
  • Can be used with AL-type aluminum Jaw coupling hubs for sizes AL090/ 095, AL099/100 and AL110 (Stainless steel hubs can be made-to-order as well)

Lovejoy Jaw in Sheer Type CouplingThe Lovejoy Jaw In-Shear Spider is radially removable, which means that neither hub (or driver/driven equipment) has to be moved to make replacements of the Spider. This saves time and money in maintenance costs. The retaining ring which encloses the Lovejoy In-Shear Spider has three small nubs which simply slide into J-shaped grooves in the perimeter of the Spider and twist-lock into place. It will not work its way loose and since there are no fasteners involved, the maintenance and removal of the Spider takes only a few minutes.

Lovejoy’s new In-Shear Spider is used with Lovejoy's L-Type and C-Type Jaw Coupling hubs which means there is no need to stock different hubs just for this new design of elastomer. The Lovejoy 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).
