Dec 09, 2016The preload of a linear bearing block is given as the percentage of dynamic load capacity that is induced on the bearing, with common preload amounts being 2, 5, and 8 percent. For example, a bearing block with a dynamic load capacity of 30,000 N and a preload of 5 percent would experience a preload force of 1500 N.

A new method for analysing nonlinear and non-stationary data has been developed. The key part of the method is the 'empirical mode decomposition' method with which any complicated data set can be decomposed into a finite and often small number of 'intrinsic mode functions' that admit well-behaved Hilbert transforms.

The roughness average (Ra) and the root mean square of surface roughness (RMS, σ) ranged from a low of 0.03, 0.05 m to a high of 0.14, 0.20 m, respectively. The number of peaks and valleys per 400 m were measured and calculated. The number of peaks ranged from 11 to 31 (greater than 99.5% Confidence Interval).
