Speedy Rail

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

A, B C, D

Concentric rollers

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

F r = ––––– (N) P 2

F a = 0 (N)

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

A, B C, D

Concentric rollers

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

F r = 2 F + ––– (N) F 1 2

F a = ––– (N) 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.
