NSK bearings prove reliable in bucket-wheel excavator

The selection of NSK spherical rolling bearings in one of the world’s largest bucket-wheel excavators has proven to be an astute decision. Despite six years of heavy duty operation at RWE Power’s opencast mine in Hambach, Germany, the bearings are still going strong – without any relubrication.
NSK spherical rolling bearings have been operating for six years in Excavator 290 without relubrication
Every day, ‘Excavator 290‘ at the Hambach mine moves up to 240,000 tonnes of coal or, using its 130-tonne bucket-wheel, excavates large volumes of overburden which is then transported to a spreader on conveyor belts in its upper structure. The four central conveyor belts located here have to work hard, not only due to the volume of material transported, but because they operate 24/7 in an adverse environment heavy with dust and moisture. This is where two NSK spherical rolling bearings are helping the mine operator maximise the operational uptime of Excavator 290.
The idea of using NSK bearings was driven by the need to reduce maintenance costs on the mine’s largest machines. Excavator 290, which is 240m long, 40m wide, 100m high and 14,000 tonnes in weight, has been in service since the end of the 1970s. With this in mind, the RWE Power product managers responsible for the conveyor belt drums set up a pilot project that involved installing a sealed, dual row NSK spherical roller bearing with tapered bore inside the drive drum of belt 2 on Excavator 290.
