Meet the requirements of the final rail travel transmission

The final rail travel transmission is often affected by impact loads and various impact forces under severe working conditions. In addition to these conditions, manufacturers also need reliable transmission solutions with high power density, strong sealing performance under wear-resistant loads and cost effectiveness of modularity.

In order to meet all the requirements, the NTN bearing final track solution consists of the following three parts:

Thin-walled tapered roller bearing

Thin-walled angular contact ball bearings

Hub assembly with integral gears and mechanical end seals

Thin-walled bearings allow for design space and cost savings, while hub units help ensure high efficiency. Mechanical end seals offer the best price. The ultimate track solution for NTN bearings is applied to large mining excavators, enabling original equipment manufacturers to develop more stringent designs, stronger loads and sealing capabilities, saving energy and reducing downtime for end users.
