"History and Origins Cacao (Theobroma) was first harvested by the Olmecs in Mexico as early as 1000 B.C. At that time it was mainly used for fortifying drinks. Over the years, the Mayas and the Aztecs adopted this use in their cultures. Cocoa became part of ceremonial rituals and cocoa beans were a means of payment. In the 16th century, the Spanish brought cocoa to Europe. In the mid-17th century, it became a popular drink. Cocoa trees were introduced to Asia and West Africa through colonies of various European countries, as there was a rising demand for chocolate in Europe. The cocoa bean is the raw material used in the production of chocolate. These cocoa beans originate from the tropical climates of South America (Ecuador). The Theobroma cacao tree is sacred to the Mayans and Aztecs. The cacao beans from the tree are harvested by hand and the raw beans are then cleaned in natural water and selected for the best quality.

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).
