JAW Coupling is a type of flexible coupling designed to transmit torque between two shafts while accommodating misalignment, reducing vibration, and absorbing shock loads. It consists of two metal hubs with interlocking jaws and an elastomeric spider element that fits between them, providing flexibility and durability. Widely used in industrial applications, JAW Couplings are known for their reliability, ease of installation, and maintenance-free operation.
Our JAW Couplings come in multiple sizes and configurations to suit different industrial needs. Below is a detailed table of standard parameters.
| Model Number | Bore Size (mm) | Max Torque (Nm) | Max Speed (RPM) | Material | Weight (kg) | Operating Temperature Range (°C) |
|---|---|---|---|---|---|---|
| JC-101 | 10-25 | 50 | 5000 | Aluminum | 0.5 | -20 to 100 |
| JC-102 | 15-30 | 100 | 4500 | Stainless Steel | 0.8 | -30 to 120 |
| JC-103 | 20-40 | 200 | 4000 | Aluminum | 1.2 | -20 to 100 |
| JC-104 | 25-50 | 350 | 3500 | Stainless Steel | 1.8 | -30 to 120 |
| JC-105 | 30-60 | 500 | 3000 | Engineered Plastic | 1.0 | -40 to 80 |
Additional parameters include allowable misalignment: up to 1.5 degrees angular, 0.5 mm parallel, and ±0.5 mm axial. All couplings meet international standards such as ISO 9001 and are tested for performance and durability.
What is the primary function of a JAW Coupling?
JAW Coupling is designed to connect two shafts, transmit torque, and compensate for misalignment while damping vibrations and absorbing shock loads in mechanical systems.
How do I select the right JAW Coupling for my application?
Consider factors such as torque requirements, shaft sizes, operating speed, misalignment types, environmental conditions (e.g., temperature, exposure to chemicals), and material compatibility. Refer to the product parameter table and consult engineering specifications to ensure optimal performance.
Can JAW Couplings handle high-speed applications?
Yes, JAW Couplings are suitable for high-speed operations, with maximum RPM values ranging from 3000 to 5000 depending on the model. Always check the specific coupling's speed rating to avoid exceeding limits, which could cause failure.
What maintenance is required for JAW Couplings?
JAW Couplings are virtually maintenance-free due to their non-lubricated design. However, regular inspections for wear, cracks, or deformation of the spider element are recommended. Replace the spider if signs of wear appear to prevent downtime.
Are JAW Couplings resistant to harsh environments?
Yes, they are designed to withstand various conditions. Models with stainless steel hubs offer corrosion resistance, while elastomeric spiders made from materials like polyurethane or Hytrel resist oils, chemicals, and moisture. Always choose materials based on your environment.
What is the typical lifespan of a JAW Coupling?
The lifespan depends on operating conditions, such as load, speed, and misalignment. Under normal conditions, JAW Couplings can last several years. Regular monitoring and timely replacement of worn parts extend service life.
Can JAW Couplings be used in food industry applications?
Yes, select models with food-grade materials like FDA-approved elastomers and stainless steel to ensure compliance with hygiene standards. These couplings are easy to clean and resist corrosion from cleaning agents.
How do I install a JAW Coupling?
Installation is straightforward: slide the hubs onto the shafts, align them properly, and insert the spider between the jaws. Secure with set screws or clamping mechanisms, ensuring even torque and correct alignment to avoid premature wear.
What are the signs of a failing JAW Coupling?
Common signs include unusual noises (e.g., squeaking or grinding), increased vibration, visible wear or cracks on the spider, and difficulty in transmitting power. Immediate inspection and replacement are advised to prevent system damage.
Can JAW Couplings be customized for specific needs?
Yes, we offer customization options for bore sizes, materials, and spider hardness to match unique application requirements. Contact our engineering team for tailored solutions based on your specifications.
