XL GR GE GS Spider Flexible Coupling Jaw Rubber Coupler

XL GR GE GS Spider Flexible Coupling Jaw Rubber Coupler

The XL star coupling ‌ is a flexible coupling with ‌ polyurethane star-shaped elastic body ‌ as the core force transmission element. It features ‌ efficient deviation compensation ‌ (angular/radial/axial) and ‌ strong buffering and vibration reduction ‌ capabilities. Its maintenance-free design significantly reduces the usage cost. The overload fracture characteristic of the elastomer can actively protect the safety of the equipment. It is suitable for ‌ medium and high-speed transmission scenarios such as pumps and conveyor lines ‌. As the top choice in terms of cost performance in the general transmission field, it provides ‌ reliable, quiet and insulated ‌ power connection for motors and reducers in an environment ranging from -40℃ to 120℃.

Youdaoplaceholder0 Strong vibration damping and buffering ‌
Polyurethane GR elastomer ‌ efficiently absorbs impact loads (such as motor start and stop, gear meshing impact), reducing the peak stress of the transmission system by more than 30%.


Maintenance-free long service life
The design is without lubrication, and the elastomer is wear-resistant and aging-resistant (with a typical lifespan of 30,000 to 50,000 hours), eliminating oil leakage pollution.


Electrical insulation safety ‌
The resistance value of the elastomer is greater than 10¹²Ω, completely blocking the shaft current and protecting the bearing from electrical erosion damage.


Cost reduction and efficiency improvement ‌
Youdaoplaceholder0 Installation cost reduced by 40%‌ : allows for larger alignment errors and shortens equipment commissioning time.
Youdaoplaceholder0 downtime loss halved ‌ : The replacement of the elastomer only takes 10 minutes without the need to move the main body of the equipment.


Protect device security
When overloaded, the elastic block breaks preferentially (the preset breaking torque is ≤ 150% of the rated torque), protecting core equipment such as motors and reducers.


Silent and environmentally friendly ‌
The operating noise is less than 70dB(A), making it suitable for clean workshops in the food and medical fields.


Lightweight energy saving
Customizable aluminum alloy wheels are 60% lighter than steel and cast iron, reducing the moment of inertia and saving energy by approximately 1.5 to 3%.
