Curved Jaw Couplings

Description

The Curved Jaw couplings can be utilized in many applications and serve as an all-purpose coupling. The basic design of the Curved Jaw allows for al higher torque capacity in a compact design. The curved tooth has a greater contact area which gives it the high torque capacity, and reduces edge pressure. It will accommodate axial, radial and angular shaft misalignments.

The hubs are produced from a variety of materials including: aluminum, gray ,iron, steel, sintered steel, and stainless steel. The spider elements are available in various durometer options in Urethane & Hytrel. The spiders can perform under normal duty cycle conditions to heavy duty cycles which include shock loading and can minimize torsional vibrations in the system.

Spider Characteristics

The curved jaw coupling includes two metal hubs and an elastomeric “spider” element. The spiders are available in
different hardness durometers, each easily identified by its color.
