INDUSTRIES SERVED: Power Transmission, Manufacturing, General Machinery, Pumps
As a trusted China manufacturer and supplier of custom polyurethane (also known as urethane and PU) couplings, we produce high-performance couplings using premium urethane blends. Our products excel in vibration dampening, torque transmission, and wear resistance—solving alignment and shock issues that damage industrial machinery.
They are known by various names depending on their specific type, such as jaw couplings, grid couplings, tire couplings, and gear couplings, and are often referred to by their manufacturer-specific names like Falk True fluid couplings.
These polyurethane couplings serve key industries: industrial machinery, pumps, mixers and agitators , power transmission critical for reliable power flow in pumps, motors, mixers, and transmission systems.

- General Machinery: Widely used to connect drive shafts in various machinery.
- Pumps: Found in pump applications to facilitate smooth power transmission and accommodate shaft movement.
Mixers and Agitators: Used to transmit rotational force and dampen vibrations in mixers.
Power Transmission: Core components in a broad range of power transmission systems.
Manufacturing: Integral to the operation of drive shafts and turbines.
-
- Absorb vibration, protecting machinery parts.
- Resist oils, chemicals, and abrasion—no frequent replacements.
- Flex to fix alignment errors (better than rigid metal).
- High-tensile polyurethane couplings handle heavy torque without cracking.
- Urethane couplings operate quietly, improving workplace comfort.
- Low-Temp Solution: Adds special antifreeze additives to prevent polyurethane brittleness at low temperatures.
- High-Temp Solution: Uses high-temperature-resistant polyurethane (e.g., NDI, PPDI) to ensure stable torque transmission at 150℃.
- Strong Acid/Alkali Solution: Integrates fluorocarbon corrosion-resistant additives to isolate corrosive medium erosion.
- Testing Guarantee: Each custom formula undergoes over 200 hours of extreme condition simulation testing for reliable performance.
- Differentiation Advantage: Unlike ordinary customization that only adjusts dimensions and hardness of polyurethane, solves coupling failure from the material root.
Elastomeric couplings, mainly means polyurethane or rubber couplings, which fall under the category of flexible (non-metallic) couplings, are designed to not only transmit torque, but to accommodate for varying degrees of misalignment (up to 3 degrees) between the shafts as well.
There are many coupling types on the market, and choosing the right one is often easy. For no significant misalignment, a rigid coupling is cheapest and most reliable. For key torsional damping needs, a jaw coupling with PU insert is best.
