The slide bearing gearboxes of the TNA and TNB type group are the result of continuous further development in our product area focusing on high-speed drive elements. This series, which has been a very successful part of RENK’s portfolio since the mid-1980s, has now undergone an extensive upgrade.

An optimized series of high-performance slide bearing gearboxes tailored to a broad range of applications was created based on many years of experience and incorporating the latest design and analysis tools. Gearboxes in this series are available with center distances from 200 to 560 mm. Two widths in eight sizes each enable an optimal selection for these application scenarios.

The slide bearing gearboxes in the TCS type group are designed to meet customer requirements according to DIN, AGMA, ISO, or API guidelines. The gearboxes can be equipped with the required instruments to enable monitoring of the temperature and vibrations. Explosion protection requirements can also be taken into account if necessary.

All pinion shafts and gear wheels are typically made of alloyed, highly wear-resistant case-hardened steel. The toothing is ground and case-hardened. The gear geometry is optimized according to the respective application scenario and the running parameters.

Optimized radial slide bearings are used for the shaft bearings based on their efficiency, oil consumption, stability, and dependability. Depending on the customer’s system concept, the gear unit can be equipped with an axial bearing on a wheel or pinion shaft. The axial bearing is integrated into a radial bearing in the standard version but can also be provided as a separate axial bearing. A mechanically driven oil pump, a rotor turning unit, or a backstop can also be installed or mounted.
