Selecting preload - skf
Depending on the application, there may be a need to preload a bearing arrangement. For example, if a high degree of stiffness or positional control is required then preload may be suitable. Similarly, where there is a very light or no external load on the bearing in operation then preload may be required to ensure a minimum load.Get Price

Diamond Drill Bit Drilling Techniques
If the tip is ever more than just warm, it is generally an indication of too little lubrication (or possibly too much speed or pressure). When drilling in hard, abrasive materials such as limestone, sandstone, hard ceramic and porcelain tiles, marble or granite, it is critical to have lots of lubrication.Get Price
Rolling processes - Al-Mustansiriya University
Rolling processes 5-1 introduction: Rolling is the process of reducing the thickness or changing the cross section of a long workpiece by compressive forces applied through a set of rolls, as shown in figure (5-1).

CalcTool: Centrifugal force calculator
The acceleration required to keep an object on a circular path is ω²r, where ω is the angular speed (=linear speed/r). This centripetal acceleration is directed towards the center of rotation, and the corresponding force is given by the Newtonian equation F=M⋅a. The ("ficticious") centrifugal force balances this force.Get Price
