Lovejoy offers four types of elastomer designs to allow for additional flexibility in addressing specific application requirements. One piece designs are used in the “L” and “AL” models (referred to as spiders) and multiple part “load cushions” are used in the “C” and “H” model couplings. The load cushions are in sets of 6 to 14 pieces depending on coupling size.

Solid Center Spider

• The solid center design is commonly used design when shafts of the driver and driven equipment can be kept separate by a standard gap

Open Center Spider

• The open center design allows for the shafts of the driver and driven to be positioned within a short distance

• Open center spiders offer shaft positioning flexibility but have a lower RPM capacity (1,750 RPM maximum for NBR, 3,600 maximum for Urethane/Hytrel®)

Cushions

• Used exclusively for the C and H Type couplings

• Load cushions are held in place radially by a steel collar which is attached to one of the hubs

Snap Wrap Flexible Spider

• Design allows for easy removal of the spider without moving the hubs

• Allows for close shaft separation all the way up to the hubs maximum bore

• Maximum RPM is 1,750 RPM with the retaining ring, but if used with the LC Type (with collar) the normal RPM rating of the coupling applies

• Style is available in NBR and Urethane only, and in limited sizes
