Lead free bearing(s) fit

[email protected]

In another article in this issue of RET-Monitor, I have given what I hope is an insight into crankcase main bearing split design (keyword: heads-blocks). Background is the accuracy of the main bearing split line geometry, primarily focused on the roundness of a main bearing bore. Since the crankshaft system does not directly rotate in the bearing bore, we will look at the bearing shells in between. As John Coxon wrote in the May 2010 issue of Race Engine Technology magazine (issue 46),...

Bearing the load

[email protected]
In most motorsport applications, bearings have had to cope with increasing loads as the requirements for higher performance of engine, gearbox and suspension components continues to increase. Recalling his days at Tyrrell, Renault's Formula One chief designer Tim Densham says, "Normally you would just open the SKF book and pick out standard bearings for most of the shafts." Things have moved on somewhat from those days, although even then some companies did make custom bearings...

Getting the best from rolling element bearings

[email protected]
Once problems with rolling element bearing reliability have been chased in NASCAR Sprint Cup Series competition, is it worth trying to gain performance improvements? The rolling element bearing does consume some power. While mechanical losses are worth a little more than you might think, there are actually two gains made for every reduction of mechanical loss implemented. Every horsepower retained through eliminating loss is a horsepower of extra power available from the engine. But there...

Rolling contact bearings

[email protected]
The terms rolling contact bearing, anti friction bearing and rolling element bearing are used to describe that class of bearing in which the main load is transferred through elements in rolling contact with each other. Friction in a rolling element bearing is present, but it is negligible when compared to the starting friction of a journal type bearing. The load, bearing speed and the viscosity of the lubrication all affect the friction within the bearing. Although it is not technically...

Bi-metal Journal bearings: Materials and construction

[email protected]

Traditional main bearing construction is based on a three-layer bearing made of a steel backing, a hard mid layer and a thin overlay of a soft material. The bi-metal bearing is constructed of only two layers, consisting of a steel backing with an inlay of an aluminium alloy. Typical bearing materials used in the construction of bi-metal bearings are a combination of the following materials: Tin, silicon, lead, copper and aluminium. The bearing material may sometimes be described as...
