The flexible jaw coupling spider from Hangzhou Raydafon are offered in the industry’s largest variety of stock bore and keyway combinations. The jaw couplings are composed of three parts: two metallic hubs and an elastomer insert called an element, but commonly referred to as a "spider". The three parts press fit together with a jaw from each hub fitted alternately with the lobes of the spider. The jaw coupling torque is transmitted through the elastomer lobes in compression.

These flexible jaw couplings spider require no lubrication and are resistant to oil, grease, moisture and other contaminants, also provide highly reliable service for light, medium, and heavy duty transmitted torque electrical motor and internal combustion power transmission applications. To be plugged in axially, easy assembly, maintenance-free. Balancing axial, radial and angular misalignment. Torque ratings from 17Nm to 3600Nm. Service temperature from -40°C to +90°C. Applications include power transmission to industrial equipment such as pumps, gear boxes, compressors, blowers, mixers, and conveyors.

The flexible jaw coupling spider features:

1. Easy of inspection,easy maintenance
2. Can absorb vibration,parallel,angular and axial misalignments
3. Identical clockwise and anticlockwise ratational charateristics
4. Both ends material is iron, intermediate for rubber materials
5. Simple configuration, setscrew type,low price
6. Hole can be self-processing,easy facilitate
