New Bearing design
The maintenance interval has doubled
Service-free cardan shaft

Beginning October 2013, Spicer GWB will introduce a “new”, innovative, sealing process for the 390.60 and 392.55 series cardan shafts. Following an evaluation period, plans are in place to make additional series available as well.

This new design will decrease annual maintenance interval by 50%, requiring bearing lubrication every 12 months, verses 6. 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.

Together with one of the leading steel manufacturers for heavy plates – Dillinger Hütte GTS – long-term tests were carried out at a turning roller table. After more than 2.5 years, there were no failures of the journal cross bearings. An in depth inspection of the grease as well a visual evaluation confirmed that the bearings were functioning as designed. Other customers in the steel industry have also confirmed the positive experiences for continuous caster rolls.

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.
