Machine bearings - Import export

Our housings and their respective bearings form bearing units which have proven themselves in machines, plant and other equipment. Bearing housings are usually made of cast iron, on request we can deliver housings in cast steel and nodular graphite cast iron. As the bearings are usually lubricated with grease, and this first lubrication holds for quite a while, most housings don’t have re-lubrication holes. There are however, gates or markings present, so that lubrication holes can be fitted if necessary. When re-lubricating, it must be ensured that excess lubricant can escape. The bearing seating points in the housings are usually machined so that the bearings are movable, so they function as floating bearings. Fixed bearings are achieved by inserting fixing rings, if these are listed in the table. Fixing rings must be ordered separately. Housings without fixing rings are delivered as floating bearing models (L) or fixed bearing models (F).

Dirt, moisture, abrasion and high mechanical loads: driving elements in agricultural machinery and the associated mounted implements are subject to severe strain. The bearings used also have to be tailored to these conditions. It is possible to increase the drive systems useful life by selecting the ideal bearings or using customised engineering. Special attention should be paid to the materials and seals. From the tractor the universal workhorse to combine harvesters, field choppers, beet harvesters and the many mounted implements for jobs such as ploughing, harvesting and fertilising, the drive systems for mobile agricultural engineering machines use bearings. These bearings have to operate in more extreme conditions than those used for many other applications.
