Polymer bearings used in oscillatingpendle axles for semi-trailers

Problem:

Bronze bearings were initially to be used in the oscillating axles of the semi-trailer. However, as these require additional lubricants, maintenance and servicing would have become very time-consuming.

Solution:

The use of iglide® G300 plain bearings as well as iglide® T500 thrust washers made the use of additional lubricants unnecessary and reduced maintenance and servicing to a minimum.

Working at a depth of 65 meters

Ets Payant, a French company, produces a pulley module which is attached under an excavator boom and moves earth out of pits up to 65 meters deep. All components must withstand weather conditions, dust and severe impacts. That is why the design engineers used igubal® W300 double joints, iglide® P fixed flange bearings, iglide® G300 thrust washers, and drylin® R aluminum shafts.
 
The pulley module is designed for a conventional 40-ton hydraulic excavator and consists of a winch module and a hose reel. It weighs just under 7 tons and is attached to the boom of the excavator with a quick coupling system. In addition, there is the guide roller module, which is also attached to the end of the shovel of the bucket with a quick coupling system.
