BLUE Jaw Coupling in China
BLUE offers a range of standard claw couplings, known for their high precision, mechanical strength, and long service life.
Jaw Type Couplings
A jaw type coupling is a flexible coupling that connects two shafts, accommodating misalignment and damping vibrations.
Jaw Flex Coupling
Claw-type flexible coupling is a flexible mechanical coupling commonly used in power transmission systems such as motors, pumps and industrial machinery.
Jaw Clutch Coupling
BLUE claw clutch couplings have long service life, strict tolerances and are available in a variety of sizes.
L jaw Coupling
BLUE L jaw couplings enable smooth transmission of torque between the shafts, reducing the risk of torque fluctuations.
Flexible Jaw Coupling
BLUE flexible claw couplings can handle certain angular misalignments and slight parallel misalignments between shafts.
Jaw Coupling Hub
BLUE jaw coupling hubs are made of iron-based metal powder, which has excellent mechanical strength and tight tolerances after sintering.
What is a Jaw Coupling?
A jaw coupling is a flexible shaft coupling that connects two rotating shafts while reducing vibration and handling small misalignments in a power transmission system. It is made of two metal hubs with curved jaws and an elastomer insert called a spider. During operation, the jaws press against the spider to transmit torque, and this compression helps absorb shock loads, reduce noise, and protect the motor and bearings from excess stress.
The design is simple and reliable. The spider can be replaced quickly when worn, and if it fails completely, the two hubs can still make limited metal-to-metal contact which allows the machine to keep running instead of stopping suddenly. Because it combines vibration damping, durability, and easy maintenance, a jaw coupling is widely used in pumps, compressors, conveyors, and many other types of industrial machinery.
Jaw Couplings Produced by Powder Metallurgy
Jaw couplings can be produced using the powder metallurgy process, which forms the jaw geometry directly from metal powder and creates a dense and durable component after sintering. This method is well suited for the curved jaw profile because it delivers accurate tooth engagement and stable concentricity, both of which are important for smooth torque transfer through the elastomer spider.
In manufacturing, iron or steel powders are compacted in a precision die that defines the overall shape of the coupling, including the jaws and the internal bore. The green compact is then sintered in a controlled atmosphere to achieve the required strength and wear resistance. Additional steps such as sizing or heat treatment may be used to improve dimensional accuracy and mechanical performance. After these processes, the metal parts are assembled with an elastomer insert to form a complete jaw coupling.
Powder metallurgy offers clear benefits for producing jaw coupling components. It supports near-net-shape forming of complex jaw profiles, minimizes material waste, and delivers consistent mechanical properties suitable for continuous industrial operation.

Benefits of Jaw Coupling
Claw couplings can accommodate shaft angle and parallelism deviations, reducing the risk of damaging other parts.
The claw coupling’s elastic spider absorbs shock and vibration, protecting the connected equipment.
They can efficiently transmit high torque without slipping, enabling high torque transmission.
If the elastic insert fails, the interlocking claws of the coupling hub maintain torque transmission and continue to operate.
Applications of Jaw Coupling
Motors and Pumps: Jaw coupling used in connecting motors to pumps, compressors, and other machinery equipment.
Conveyors: Jaw couplings help transmit power in conveyor systems, compensating for shaft misalignment and reducing wear.
Agricultural Machinery: Jaw couplings efficiently transmit power and are often applied in agricultural equipment such as tractors, textile machines, harvesters, and irrigation systems.
