Tailored coupling designs based on specific torque, speed, and misalignment requirements.
We provide comprehensive engineering support to ensure optimal coupling selection, installation, and performance.
Understand radial, angular, and axial misalignment tolerances for different coupling types.
Selection guide for jaw coupling spiders based on torque, temperature, and chemical resistance.
Reference charts for standard keyway dimensions and tolerances.
Precision fit guidelines for shaft and hub to prevent slippage and wear.
Step-by-step method to calculate required torque with service factors.
Clamp, set screw, and flange mounting options with pros and cons.
Identify imbalance, misalignment, looseness, wear, and resonance through vibration analysis.
Professional techniques including laser alignment and dial indicator methods.
Avoid common failures by selecting the right coupling for your application.
Disc couplings use thin metallic discs for flexibility, offering zero backlash and high torsional stiffness. Jaw couplings use elastomer spiders to absorb shock and dampen vibration, making them better for misalignment and less rigid applications.
Consider torque, speed, misalignment type, environmental conditions, and required service life. Our technical guides and engineers can assist with proper selection to avoid premature failure.
Yes, many of our couplings, especially disc and bellows types, are precision balanced for high-speed operation up to 20,000 RPM or more, depending on size and model.
Yes, we provide OEM and ODM services. Our engineering team can design and prototype couplings based on your specific requirements for size, torque, material, and performance.
Our manufacturing processes comply with international quality standards. We follow strict material and dimensional tolerances to ensure reliability and interchangeability.
