Rotary Cooler Riding Ring & Trunnion Contact Stress Calculator

Calculate Hertzian peak contact compressive stress ($sigma_H = sqrt{rac{F (1/ ho_1 + 1/ ho_2)}{pi L (rac{1- u_1^2}{E_1} + rac{1- u_2^2}{E_2})}} < 45,000 ext{ PSI}$) between forged alloy steel riding rings (tires) and support trunnion rollers: eliminate surface spalling, pitting fatigue, and mechanical failure yields.
