Following the developments we have made in lubrication-free technology, the demand for lubrication-free chains has increased rapidly over the past couple of years. More and more people are now opting for this type of chain, especially for environmental and economic reasons. The advantages are obvious. The use of lubrication-free chains leads to enormous cost savings in the field of maintenance and servicing. Since no relubrication is necessary in these cases, faults caused by wrong relubrication and maintenance are excluded.
By means of extensive test runs on our test stands, the research and development team at KettenWulf has managed to develop two fundamental technologies for manufacturing lubrication-free chains. Depending on the environmental conditions and environmental influences, we are able to offer lubrication-free chains in sealed and non-sealed designs.
LOW MAINTENANCE CHAINS
We have developed various sealing systems for chain joints, especially for use in abrasive or corrosive media. Thanks to these sealing systems, the penetration of dirt and moisture is largely prevented. This way, good lubrication is retained in the chain joint over a long period of time.
In this design, the chain joints are sealed by a sandwich seal and other special sealing rings. The chain joints are regularly relubricated, however at relatively long intervals. Thanks to the reduced lubricant consumption, it is possible to reduce costs and improve processes.
SPROCKETS WITH NOISE ABSORPTION SYSTEMS
During the operation of plant annoying noise can often develop when the chain enters the sprocket. To significantly lower these noises and to improve working conditions, KettenWulf has developed special noise dampers which are mounted on the sprockets.
These noise absorption systems used on the market for the first time by KettenWulf ensure that the chain joints no longer dash against the tooth gap, but rather are smoothly guided into it This reduces the operational chain noise to such an extent that it can usually no longer be heard above normal ambient noise levels.
