Rollers load with force 'P' applied on the rail axle

P, P 1 = Applied forces (N) F r = Radial load (N) F a = Axial load (N)

F r = F a = F · ( ––––– ) (N) 1 2

F = P · ( ––––– ) (N) 1 2· 2

Fig. 158

Rollers load with 'P 1 ' force applied at 'L' distance (mm) from rail centerline

P, P 1 = Applied forces (N) F r = Radial load (N) F a = Axial load (N)

F r = F a = ––––– (N) F+F 1 2

F 1 = ––––– (N) P 1 · L 2 · d

F = P 1 · ( ––––– ) (N) 1 2· 2

Important : the load on most loaded rollers must be, for each roller type, less or equal to the corresponding rated load on the catalogue.
