Product Description

A jaw coupling is a type of general purpose power transmission coupling that also can be used in motion control (servo) applications. It is designed to transmit torque (by connecting two shafts) while damping system vibrations and accommodating misalignment, which protects other components from damage. 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. Jaw coupling torque is transmitted through the elastomer lobes in compression.

The elastomer of the spider can be made in different materials and hardness, which allows the user to customize the coupling to best serve their application. Considerations for elastomer selection include ability to dampen vibration, ability to handle misalignment, operational temperature range, speed of equipment, and chemical conditions.


1 jaw flexible coupling:

a) Applicable to all types of machinery and hydraulics

b)Small volume and large transmitted torque

c)To be plugged in axially, easy assembly, maintenance-free

d) Balancing axial, radial and angular misalignment

e)Dimensions of bore d,d1 available on customers requests

f)Applicable from -40 to +100°, temperature peaks up to 120°

2.FCL flexible coupling

a)Flexible coupling model FCL is widely used for its compact designing ,easy installation, convenient maintenance, small size and lightweight

b)As long as the relative displacement between shafts is kept within the specified tolerance, FCL flexible coupling will operate the best function and have a longer working life

c)Greatly demanded in medium and minor power transmission systems driven by motors, such as speed reducers ,hoists ,compresses ,conveyers ,spinning and weaving machines and ball mills

dPermitted relative displacementI)Radial displacement 0.2-0.6mm II)Angel displacement: 0°0′ – 1°30′
