Spider Performance

Hytrel is a flexible elastomer designed for high torque and high temperature operations. Hytrel can operate in temperatures of -60° to 250° F (-51° to 121° C) and has an excellent resistance to oil and chemicals. Not recommended for cyclic or start/stop applications.

Lovejoy 25310 Size L-AL 090-095 Open Center Type Hytrel Jaw Coupling Elastomer

 

This Lovejoy open center type jaw coupling elastomer replaces open center elastomers on Lovejoy jaw style flexible coupling assemblies and is made of thermoplastic polyester elastomer (Hytrel) for strength, flexibility and heat resistance.

The open center design allows for the shafts of the driver and driven to be positioned within a short distance of each other but has a lower RPM capacity than solid center elastomers. It can operate in temperatures ranging from -60 to 250 degrees F (-51 to 121 degrees C).

Lovejoy jaw style couplings are a type of flexible coupling suitable for use in various industrial power transmission applications such as compressors, blowers, pumps, conveyors, mixers, and gear boxes, among others.

Flexible couplings are used to link two rotating shafts that are not aligned in order to transmit the rotational power, known as torque, from one shaft to the other. Most flexible couplings consist of two hubs and a middle assembly; each hub attaches to a shaft while the middle assembly flexes between the hubs to accommodate the misalignment of the two shafts.

Shaft misalignments are generally either parallel or angular and cause complications to transmitting rotational power from one shaft to another in the form of stresses, loads, vibrations, and other forces, which vary from one type of misalignment to another.

Flexible couplings are used in a broad range of applications, such as in motor vehicles, conveyors, escalators, agricultural, forestry and mining equipment, aeronautics, robotics and space exploration, among others.

Lovejoy manufactures flexible couplings, universal joints, variable speed drives and various other transmission and mechanical power products. Their products meet the standards of the International Organization for Standardization (ISO), the Deutsches Institut für Normung (DIN), the American National Standards Institute (ANSI), the American Gear Manufacturers Association (AGMA), the Society of Automotive Engineers (SAE) and Japanese Industrial Standards (JIS) for quality assurance.

The company, founded in 1900, is based in Downers Grove, IL.
