UNEFLEX Tyre Couplings

The Uneflex tyre coupling is a highly flexible rubber fabric coupling appropriated for compensation of big shifting and shock energies. This coupling's distinct advantages make it highly sought after in various industrial applications.

We take pride in being recognized as the best Tyre Coupling Manufacturer worldwide. At our one-stop shop, our specialized team is dedicated to helping you find the right product for your specific needs.

With its exceptional elasticity, the coupling effortlessly accommodates significant offsets in all directions without causing wear. This coupling excels in absorbing torque peaks and dampening vibrations, thanks to its rapid smoothing properties, ensuring it operates free from backlash.

The user-friendly design of the Uneflex shaft coupling is one of its standout features. The elastic tyre, made of natural rubber reinforced with fabric, is mounted on the hub and secured by fastening the rings with screws. A split in the rubber tyre allows for radial replacement without the need to move the hubs or realign the driver or driven equipment, significantly minimizing downtime.

The tyre fabric can be aligned either radially (R arrangement) or transversely (X arrangement), each offering different spring stiffness. While R fabric arrangement tyres have lower torsional stiffness, the X arrangement is better suited for reverse operations and shock loads.

The Uneflex tyre coupling boasts an extensive range of series options. These include standard models, taper lock bushings, pump drive spacers, brake discs, and brake drums in compliance with metallurgical plant crane standards. Additionally, they offer SAE flywheel assemblies and special design tyres for balancing greater misalignments in drives with sliding rotor motors, among many other designs to suit various applications.

Features and Benefits of Tyre Couplings

• Zero maintenance: No routine maintenance or lubrication is required.
• Quick and easy installation and replacement: Allows swift and easy element installation and replacement without moving hubs or realigning the driver or driven equipment, reducing downtime.
• High misalignment capabilities: Compensates for significant angular, axial, and radial misalignments.
• Vibration dampening and shock absorption: Provides damping properties to torsional vibration and sudden load variations, protecting the entire system.
• Working temperature range: Standard natural compound tyres work from -20°C to +80°C, while chloroprene tyres operate from -15°C to +100°C.

Application Fields for Tyre Couplings

• Excellent for applications with difficult alignment characteristics.
• Perfect for applications with vibrations and thermal expansions.
• Handles high torque peaks and immense shocks effectively.
• Especially suitable for use in cranes and roller table drives in metallurgical plants.

UNE has a wealth of experience in pump installations. The UNEFLEX elastic tyre coupling shines in such applications as it tolerates strong misalignments and isolates vibrations effectively. During pump startups, the tyre coupling prevents machinery from experiencing severe vibrations or defects, ensuring longer machinery life. The elastic nature of the coupling absorbs engine startup shocks, consequently extending the life of the pump and gear.

Flexible Spacer Coupling

Complementing the UNEFLEX flexible tyre couplings, UNE also produces spacer couplings. This includes a Uneflex tyre coupling integrated with a spacer flange assembly. For more details, please visit Custom Universal Joints.

The spacer couplings are advantageous in applications where it is beneficial to move either shaft axially without removing the gear and pump.

UNEFLEX Flexible Rubber Spacer Coupling Easy to Remove

Using this tyre coupling design allows for removing the mechanical seal more easily for maintenance and repairs without moving either the pump or the gear. Designed with standard distances between shaft end dimensions (D.B.S.E.), these couplings can be customized according to your application requirements.
