For designers who have had to compromise by using larger couplings than otherwise necessary, or coupling styles that are less desirable, the new elastic metal insert couplings could be just the solution.

Rolling bearings of different designs but with adjusted, identical outside dimensions reduce the number of different parts contained in modular systems. Economies of scale significantly reduce the manufacturing costs.

Safe and accurate transmission of torques is essential for precision drives of cross cutters. This is ensured by the use of steel bellows couplings with force-fitted shaft-hub connection.

By changing to NSK Molded-Oil mounted-unit inserts, an international drinks producer has overcome repeated problems of premature insert failures on the drive system of four vital sorting conveyors. The move has improved service life notably, leading to an annual saving of more than € 5000.

Monitoring the condition of bearings is not only a way to detect the need for their replacement, but a way to draw conclusions about the state of the entire machine or system. To illustrate the benefits of NSK’s Condition Monitoring Service (CMS), two practical examples highlight what can be offered to users of grinding machines.

Faced with regular bearing failures on the blade support of a concrete pipe-slotting machine that would cause 8 hours of downtime each time, the UK-based company in question turned to NSK for assistance. As part of NSK’s AIP Added Value Programme, a team of engineers scrutinised the application and determined that the ingress of concrete dust into the bearings was the root cause of the problem.

With the highest outdoor elevator in the world, travellers are able to marvel at the unique rock formations in the Wulingyuan region of the Zhangjiajie National Park in Central China, which is one of the ‘Unesco’ World Heritage Sites. Elevator brakes, only of the highest quality ensure that travellers experience the natural landscape without any safety concerns.
