Lovejoy 10621 Size L-AL 075 Solid Type Jaw Coupling Elastomer, Buna-N Rubber, Inch, 1.75" OD, 0.44" Length, 90 in-lbs Nominal Torque

Lovejoy offers multiple types of elastomer designs to allow for additional flexibility in addressing specific application requirements. Each of the types provide different performance capabilities for the coupling, including torque rating, RPM speed, dampening capacity, chemical resistance, and operating temperature ranges. Within the different elastomer types are two different designs, solid center spiders and open-center type spiders. The solid center design is the commonly used design when shafts of the driver and driven equipment can be kept separate by a standard gap. The open-center design allows for the shafts of the driver and driven to be positioned within a short distance. Open-center elastomers offer shaft positioning flexibility but offer lower RPM capacity.
