PRMF 758070. Wrapped bronze flanged bushing. SKF wrapped bronze flanged bushings are suitable for oscillating, rotating and linear movements, and can accommodate radial loads as well as axial loads in one direction. They are an excellent solution for dirty environments where high levels of contamination make relubrication necessary.

Equation (3.2) shows the calculation of wear rate of a material. Eq. (3.2) where t =wear (in), K =wear factor (in 3 -min/ft.lb-hr), P = pressure (psi), V = velocity (ft/min), and T = time (hr). Like PFA, FEP forms a smooth and slippery surface that has many practical applications because of its low coefficient of friction.

The porous aerostatic bearing is a new supporting structure that is widely used in precision and ultraprecision engineering and the aerospace and other fields. The aerostatic bearing has a good bearing capacity and static stiffness. In this work, the numerical and experimental research on the static characteristics of an aerostatic bearing based on a porous SiC ceramic membrane is presented

Factors in Life of Bearing: Standard downthrust on U.S. MOTORS® products is 1 year (8800 hours) minimum and 5 years average per AFBMA B-10 method. Momentary upthrust is calculated at 30% of standard downthrust. Thrust life is normally not a factor since bearings only operate in this condition for a few seconds at start.

Since the pipeline is to be tested at 200 psi, the total thrust is 2 x 9300 or 18,600 lbs. • In the table below, you will find that the bearing power of sand is 2000 lbs. per square foot. Dividing the total force of 18,600 lbs. by 2000 lbs., gives a total required thrust backing of 9.3 square feet or an area slightly over 3 ft. x 3 ft.
