After calculating P10, comparison with the specific load rating C10 (table Specific load rating C10 and suspension R10) will show whether the rotary stroke bearing is dimensioned correctly.
Requirement: P10 ≤ C10
The deflection A is calculated as specified in the section Radial load as pure moment.
Load of the most heavily loaded ball zone
Uniform radial force
PR = 1000 N
l = 300 mm
Contact path e = 200 mm
Distance between the ball zones Ii = 100 mm
P10 = g · M + h · PR
M = PR · I
M = 1000 N · 0.3 m = 300 Nm
g = 2 m-1 (in the diagram contact path e / torque factor g)
h = 0.11 (in the diagram contact path e / radial force factor h)
P10 = 2 m-1 · 300 Nm + 0.11 · 1000 N
P10 = 710 N
