calculation of slide shoe bearing
Optimal Performance Design Guidelines for Thrust Slide …
Williamson are applied to calculate the resultant lubrication performance for a given value of the friction area of the thrust slide-bearing, thus determining the friction coefficient for the thrust slide-bearing. With increasing friction area, the friction coefficient was found to decrease gradually, due to the larger oil film force.

Sliding Bearing
Journal bearings. Peter R.N. Childs, in Mechanical Design Engineering Handbook (Second Edition), 2019 5.2 Sliding bearings. The term sliding bearing refers to bearings where two surfaces move relative to each other without the benefit of rolling contact. The two surfaces slide over each other and this motion can be facilitated by means of a lubricant which …

Our bearing service and repair specialists find that 50 percent of the bearings submitted to us haven't reached their calculated lives. In some cases, the cause is contact fatigue (inclusion origin, point surface origin, geometric stress concentration and micro-spalling). In 90 percent of the cases, the cause is non-fatigue factors, including:

How to Calculate a Bearing. To calculate a bearing, find the angle clockwise from north. Start by drawing a vertical line representing north at the first location. Draw a line connecting the start location to the end location. Measure the clockwise angle between the north line and this line. For example, the bearing from A to B is 100°.
