Four Ball Tester - About Tribology

3/12/2019· Four Ball Tester, also known as Shell four ball tester, is used to characterize lubricants properties, such as wear prevention (WP), extreme pressure (EP) and frictional behavior (various testing standards are listed below). The tester consists of four balls in the configuration of an equilateral tetrahedron, as shown in the figure below.

If the plate bearing test is carried out below the groundwater level, it is essential to lower the groundwater level by a system of wells or other measures outside and below the test position. The preparation of the test surface may cause an unavoidable change in the ground stress which may result in irreversible changes to the subsoil properties.

These are the 5 most common C codes for internal bearing play: C1, C2, C3, C4 and C5. If a bearing has a C code, it offers extra internal clearance. C1 offers the least extra clearance, C5 offers the most extra clearance. The extra margin C3 offer is considered ''normal''. Bearings with C3 are in fact the most commonly used.

How do I determine the loads on a bearing? - Bearing Tips

19/6/2017· Those are the three basic load components on the bearing. We have to consider the weight of the component, the force and the drive forces. In this case it was a belt, but it could be chain driven or gear driven. And then you have the fly bills. If we know the distances, we can use stats to determine the load on the bearing.
