This technology, Molded Oil™, can transform the performance of bearings used in cement plants by replacing existing, and often costly, methods of lubricating machine parts. NSK offers Molded Oil™ technology on standard deep groove ball bearings and spherical roller bearings in outside diameter sizes up to 250mm.
Recycled materials in cement . In 2006, the cements manufactured by Lafarge had an average additive content of 23%. These additives were of natural origin, such as limestone and volcanic rock, or industrial origin, for example blast furnace slag (a steel industry byproduct) or fly ash (from coalfired power plants).
Dec 14, 2016· In this journal bearings a shaft or journal rotates inside the bearing over a layer of lubricating oil, separating the shaft and bearing due to fluid dynamic principal. The two types of journal bearings commonly used are shell and tilting pad. The shell bearing is used in heavily loaded areas.
If a thrust bearing is used, it should be of a tilting pad, selfleveling design. With a doublehelical gear unit, thrust bearings, if used at all, should be on the lowspeed shaft only, to accommodate loads in both axial directions. Journal and thrust bearings must be split for removal and installation without having to remove the coupling hubs.

The steelbacked whitemetals used in the journal and thrust bearings of rotating plant are generally tinbased, SnSb8Cu3 being the most commonly used alloy. Higher strength can be obtained from alloys of more complex composition, but at the expense of loss of ductility. A zinccontaining alloy, SnZn30Cu1, is used in some marine applications.
: Rocker Bridge Bearing. Pin bearing is a fixed bearing that make room for rotation movement through the application of steel pin. It has similar structure and component like rocker bearing apart from the bottom of pin bearing which is flat and fixed to the concrete pier, as can be observed in Figure4.
Portland Cement . Cement: is a material with adhesive and cohesive properties which make it capable of bonding minerals fragments into a compact whole. For constructional purposes, the meaning of the term "cement" is restricted to the bonding materials used with stones, sand, bricks, building stones, etc.
