Double Row Angular Contact Ball Bearings Loads

Minimum load, equivalent bearing loads

Minimum load

Equivalent dynamic bearing load

F_a/F_r ≤ e → P = F_r + Y₁ F_a
F_a/F_r > e → P = X F_r + Y₂ F_a

Equivalent static bearing load

P₀ = F_r + Y₀ F_a

Symbols

d_m	bearing mean diameter [mm] = 0,5 (d + D)
e	limiting value of F_a/F_r for the applicability of different calculation factors (technical specification for each product, product table)
F_a	axial load [kN]
F_r	radial load [kN]
F_rm	minimum radial load [kN]
k_r	minimum radial load factor (technical specification for each product, product table)
n	rotational speed [r/min]
P	equivalent dynamic bearing load [kN]
P₀	equivalent static bearing load [kN]
X, Y₀, Y₁, Y₂	calculation factors (technical specification for each product, product table)
ν	actual operating viscosity of the lubricant [mm²/s]
