New Bearing design for series GWB™ 390.70 and 392.65
The maintenance interval has doubled
Service-free cardan shaft as an option
Dana now offers GWB 390.70 and 392.65 series cardan shafts with new and innovative bearing design. Plans are in place to make additional series available.
This new design will decrease annual maintenance interval by 50%, requiring bearing lubrication every 12 months, verses 6 under consideration of the enviroment, adjustment according to experience. As an alternative, the new design can also be installed as a service-free (lube for life) product. This means, no required lubrication maintenance for a defined period of operation, and thus, no lubrication costs.
The new GWB journal cross design has performed impressively in extensive laboratory tests, including, among others, the mud bath and grease loss analysis test and it has proven itself, in the harshest real world conditions.
The service-free bearing design can be built with central or 4-point lubrication, on request. For guaranteed top performance, it is imperative that the GWB recommended special grease be used at every lubing.
