Dynamic® Tyre Couplings
TransDrive Dynamic® Tyre Couplings are specifically engineered to absorb shock, vibration, and torsional movement – offering reliable protection against twirl, twist, impact, and abrasion. Its maintenance-friendly design requires no oil or grease, and replacement of the tyre element can be performed quickly and easily without the need to disconnect motors or adjacent components, significantly reducing downtime.
Versatile in its application, the coupling accommodates dissimilar shaft connections using the same hub, providing flexibility across a wide range of equipment setups. Constructed from high-performance polyurethane, the tyre element delivers outstanding resistance to water, chemicals, and harsh environmental conditions – ensuring long-term durability and consistent performance.
With its combination of strength, simplicity, and adaptability, the TransDrive Dynamic Tyre Coupling is an ideal solution for industrial power transmission systems where efficiency, reliability, and easy of maintenance are essential.
