Gear couplings high-speed series

Built on the basis of more than 75 years of experience in the development and production of these high-quality drive elements, RENK’s gear couplings in the high-speed series are the ideal product, especially when it comes to transmitting maximum speeds. Our high-speed series includes three different series. The ZT, TF, and TSB ranges are available in different variants to meet the needs of the respective application.

All of the ranges are tooth tip centered and equipped with a single tooth lubrication system. The existing high standard of quality ensures that components can be replaced. The high-speed series offer you a high level of protection against overloads with low axial forces. Our couplings are also optionally available in a API 671 version.


Series ZT

Specially designed for maximum speeds

Nitrided and ground internal and external toothing

Toothing quality Q = 4-5 as per DIN 3962

Series TF

Specially designed for high speeds

Nitrided internal and external toothing

Toothing quality Q = 6–7 as per DIN 3962

Series TSB

Specially designed for moderate speeds

Naturally hard internal and external toothing

Toothing quality Q = 7–8 as per DIN 3962

Gear couplings

Basic series

Our extensive range of couplings, including a wide range of series and versions, offers you complete freedom to design a shaft connection that fits your needs. It also gives you the certainty of selecting the ideal solution, even for the most difficult drive applications.

Gear couplings

Gear joint coupling

In the case of gear joint couplings, the joint connection is torsionally rigid but flexible on all sides, which offers considerable advantages over a rigid coupling.

Gear couplings

Gear spindle coupling

Gear spindle couplings are mainly used where large torques have to be transmitted with very small outside diameters and, at the same time, high misalignment capability is required.
