In many cases; the inner bore dimension of the bearing has been limited by the layout of the machine or equipment. Regardless of the number of operating life; the static load safety factor and the economic function are all at the demand; before the other dimensions and layout of the bearing are selected at the end; It must be scaled. The calculation involves comparing the bearing practice load to its load.
The static load of the rolling bearing means that the bearing is stopped after loading (no relative movement between the inner and outer rings) or the rotation speed is very low. In this case, the safety factor of excessive plastic deformation of the raceway and the rolling body is calculated.
Most of the bearings are subjected to dynamic loads; the inner and outer rings are used for relative motion; the scale calculation is used to check the safety coefficient of early fatigue damage of the rolling races and rolling bodies.
As long as it is in special circumstances; the nominal life calculation is performed on the number of operational lifespans that can be reached according to DIN ISO 281. For the depiction of economic function; the bearing capacity of the bearing should be fully utilized. The use of bearings; then the accuracy of the calculation of the bearing scale is more important.

Maijin outdoor WPC has the same processing performance as the log. It can be nailed, drilled, cut and bonded. It is connected and fixed with nails or bolts. The surface is smooth and delicate without sanding and painting. The paint has good adhesion and can be painted according to personal preference. The product has better physical properties than log, better stability than traditional wood, no crack, warpage, no wood scar, twill, adding colorant, film or composite surface can be made into colorful products, without time-consuming maintenance.

Maijin decking is divided into single extrusion board, co-extrusion board and soft clad board; the inner core is divided into round hole, square hole and solid; the grain is divided into horizontal grain and wood grain.
