SS metal (polished)/0.02 - 0.035
Quenched metal/ 0.01 - 0.015

-- Load used
Specifications tables show the figures of rest loads. It is recommended to follow the formula below to calculate the loads used. (The figures may vary depending on specification conditions, i.e. speed, deflection load, impact, etc.)
