Standard Jaw Coupling Supplier

We have a wide range of jaw coupling parts for quick delivery and no mold fees required.

Standard jaw type coupling bore sizes (mm): 3, 6, 9, 12, 15, 19.

Standard jaw type coupling OD (mm): 16, 28, 35, 45, 54, 64.5, 85, 96, 115, 127.

Standard jaw type coupling hub length (mm): 6.6, 15.6, 19, 21, 25.5, 27, 35, 43, 45, 54, 64.

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.

Powder Metal Jaw Coupling Manufacturing Process

Powder metallurgy is a precision manufacturing process with a continuing and stable accuracy of up to 0.01mm, which requires strict control at each stage to ensure the quality of the final part. Any deviation or error during the process may result in the rejection of the entire batch.

14-Powder Metallurgy-Designing

Designing

Mold design is a critical process that must consider the desired part geometry, material properties, production volume, and cost-effectiveness.

Powder Metallurgy Compacting Mold

Tooling

Powder metallurgy tooling includes upper and lower punches, die, and core rod. The mold needs to have excellent strength, hardness and wear resistance.

13-Powder Metallurgy-Mixing

Mixing

Mixing is the process of blending metal powder with binders to improve its uniformity and fluidity, promoting better material consistency.

16-Powder Metallurgy-Compacting

Compacting

Conpacting is a process that presses metal powder into mold cavity through powder compaction machine to get a green compact part.

17-Powder Metallurgy-Sintering

Sintering

Sintering heats the green compact to a temperature below its melting point in a controlled atmosphere to obtain the desired mechanical properties.

18-Powder Metallurgy-Sizing

Sizing

Sizing corrects dimensional deviations after sintering and enhances product accuracy. It requires an additional, simpler set of molds compared to the forming mold.

19-Powder Metallurgy-Vibrating

Tumbling

Tumbling removes burrs and flash from a part's surface by vibrating it with abrasive media, such as stone or ceramic, resulting in a smoother finish.

20-Powder Metallurgy-Machining

Machining

Machining can achieve complex shapes that cannot be pressed by powder metallurgy, such as transverse holes and screw threads.

21-Powder Metallurgy-Blacking

Blackening

Blackening process, or steam treatment, forms an oxide layer to prevent rust and increase hardness, offering a cost-effective solution.

22-Powder Metallurgy-Hardening

Hardening

Hardening enhances the material's strength and hardness through carburizing or nitriding, resulting in improved wear resistance and fatigue life.

22-Powder Metallurgy-Inspecting

Inspecting

The inspecting process is always a critical step that ensures quality and performance through BLUE inspection standards before shipping.

23-Powder Metallurgy-Packaging

Packaging

BLUE's packaging process uses anti-rust paper, vacuum, blister and other methods to ensure that the product is intact during transportation.

BLUE's Powder Metallurgy Manufacturing Equipment

BLUE has a complete range of advanced powder metallurgy production equipment, including 25T to 1000T compaction press, conveyor belt sintering furnace, vacuum sintering furnace,  sizing press, CNC machining equipment, hardening furnace, etc.
