Clevite is the number one name in replacement engine bearings – delivering on the track and in machine shops around the country. With track proven performance in engines with thousands of horsepower, it is obvious Clevite has the strength to handle any light vehicle application.As more and more OE manufacturers shift to aluminum bearings in OE engines, Clevite has introduced a new line of engine bearings designed to be the highest quality replacement bearings in the industry. Clevite Bimetal engine bearings carry on the tradition and reputation that Clevite has built throughout the course of time.Clevite Bimetal engine bearings feature a 100% lead free aluminum silicon bi-metal material, which includes 60% more silicon than the leading competitor’s bi-metal material for better conditioning of journal surfaces. These Bimetal bearings also offer greater wear resistance than the leading competitor’s bi-metal material, as well as greater seizure resistance. Clevite Bimetal bearings feature 100% bored ID’s for precision and surface characteristics and where appropriate – straight shell main bearings utilizing an “umbrella” groove that allows for superior oil control and improved pressure.Clevite® Bimetal engine bearings are of aluminum, tin, silicon Bimetal type of material and construction. These offer the engine rebuilder an Oe type of bearing for engines going into light duty applications. They are only recommended for applications where all engine components have been reconditioned to engine manufacturers original specifications.Bimetal engine bearings are not recommended for Heavy Duty service where heavy demands are placed on the engine or High Performance applications where Clevite TriMetal is still the ultimate performance choice.

Pierburg Pump Technology has mapped out a variety of approaches with a view to ensuring dependable lubrication and reliable regulation of the oil supply system under all operating conditions. The aim is to be able to supply pumps that address all the functional requirements while maintaining maximum efficiency and achieving the slightest possible losses. Pierburg Pump Technology’s design department has highly advanced design and simulation tools as well as extensive expertise in the structural analysis of finite elements (static, modal, spectral and fatigue), computer fluid flow dynamics (CFD) and multi-body simulation. Multi-body analysis were introduced to obtain precise information on the factors affecting moving components. The advantage of vane pumps is that they can be simply and continuously controlled over a large adjustment range with constant efficiency. What’s more, they can be positioned both on the crankshaft and in the oil pan. The solution chosen by Pierburg Pump Technology permits the use of various passive and active forms of control.
