Lovejoy 68514411494 L/AL099/100 Spider is a standard SOX (NBR rubber) elastomeric element for L-Type and AL-Type jaw couplings. This solid-center spider fits both L099 and L100 series sintered iron or aluminum hubs, providing high torsional dampening and shock absorption. The NBR material offers a standard operating temperature range of -40°F to 212°F and is the baseline torque rating for this coupling size.

• The L Type coupling consists of two standard L Type hubs and one spider.

Spider Performance

• Nitrile Butadiene (Buna N) Rubber is a flexible elastomer material that is oil resistant, resembles natural rubber in resilience and elasticity and operates effectively in temperature range of -40° to 212° F (-40° to 100° C). Good resistance to oil. Standard elastomer. (Also applies to SXB Cushions. )

Elastomers in Compression

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

Notes

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