Tunneling Eequipment

The tunneling drilling equipment requiring high stiffness with high capacity. Also the lifetime & reliability being a major issue of those applications.

Our Triple row roller slewing ring gear and swing bearing is able to carry different loads at the same time, and their load carrying capacity is larger than that of a similar configuration of ball bearing. The roller elements are separated by spacers which can be individual or they can be segmented. Some of the heavy bearings incorporate the use of continuous cage, which are usually made from bronze. We offer the best reliability and precision, proven by extensive in-house testing, for the applications.

Our slewing ring bearing is best solution for tunneling boring machine.
