Jaw Couplings with a Simplified Structure
Power is transferred by the polyurethane elastomer with the elastic force of rubber, which has superior vibration and shock
absorbability. High torque transmission that is more than double that of conventional mikipulley jaw couplings is achieved
by pursuing the optimal shape.
Although it is a high transmission torque, misalignment reaction force has been significantly reduced by undercuts of the
inner diameter side.
While use with no backlash is available by a design allowing preliminary compression (ALS-R ALS-Y), the couplings can
be used for the target shaft or bearing with damage-free.
Also, the couplings are compliant with the EU Restriction of Hazardous Substances Directive, RoHS Direcctive, that
prohibits six hazardous materials such as mercury, lead, and others.

Versatile Jaw Couplings for Diverse Applications

Our jaw couplings are engineered for use in demanding power transmission scenarios, including industrial conveyors, pumps, compressors, and motors. Their flexible structure compensates for slight misalignments and the spider element absorbs shocks and vibrations, helping extend machine life. Available in a range of surface treatments and bore types, they provide compatibility and reliability across various equipment setups.

Advanced Corrosion Resistance and Durability

Manufactured with materials such as cast iron, aluminium, and steel, our jaw couplings receive high-quality finishesanodized, powder coated, or polishedoffering superior resistance to corrosion in challenging environments. These durable components are designed to meet ISO and DIN standards, ensuring long service life even in heavy-duty industrial use cases.

FAQs of Jaw Couplings:

Q: How are jaw couplings installed and what types of assembly are available?

A: Jaw couplings can be assembled using either clamp or set screw methods. The clamp type enables quick, secure installation without damaging the shaft, while set screw types provide a simpler, cost-effective connection. Both assembly methods are straightforward and suitable for a wide variety of power transmission applications.

Q: What is the role of the spider element, and how does its hardness affect coupling performance?

A: The spider element, made of polyurethane and available in green, red, or custom colors, serves to cushion the connection between coupling hubs. Its standard hardness is 80 Shore A, balancing flexibility with torque transmission. Custom hardness options can be provided for applications requiring specific damping or stiffness characteristics.

Q: When is a jaw coupling recommended over other types of shaft couplings?

A: Jaw couplings are recommended when you require moderate misalignment accommodation (up to 1 mm), reliable vibration damping, and straightforward maintenance. They are ideal for applications such as pumps, compressors, motors, and conveyor systems, especially where flexible shock absorption and ease of installation are needed.

Q: Where can these jaw and spider couplings be effectively used?

A: These couplings are widely used in industrial environments across India, particularly in power transmission assemblies for machinery like motors, pumps, compressors, and conveyor systems. Their high corrosion resistance and vibration-damping features make them suitable for both indoor and outdoor settings.

Q: What materials are available for jaw couplings and how do they influence performance?

A: Jaw couplings are offered in cast iron, aluminium, and steel for the hubs, and polyurethane for the spider. Steel provides maximum strength, aluminium offers lightweight corrosion resistance, and cast iron is well-suited for heavy-duty applications. The polyurethane spider ensures vibration damping and flexibility.

Q: How does the surface treatment impact the durability and use cases of the coupling?

A: Surface treatments like anodizing, powder coating, or polishing enhance the couplings resistance to corrosion and wear. This makes the couplings dependable for long-term use in harsh or chemically aggressive environments, improving their operational lifespan and reliability.
