Calculation of the permissible load of rubber-metal buffers

Technical information on rubber-metal buffers and rubber-metal rails according to DIN ISO 3302-1 in standard quality: NK (natural rubber)

Determination of the spring travel f_max according to the load type

Load as end stop (impact load) - permanent (max.): f_max = H × 0,50
Load as end stop (impact load) - rare (max.): f_max = H × 0,60
Continuous load - static (max.): f_max = H × 0,15
Vibration damping: f_max = H × 0,05 bis 0,10 × H

Diameter expansion:
f = 0,50 × H / D₁ = 1,40 × D

Impact surface:
D₂ > 1,25 × D

Impact direction:
α_max ± 4°

Round buffer

Please enter the values for diameter and rubber height of your round buffer in the following fields to have the form factor k calculated

Read the value for the modulus of elasticity (Ec) as a function of the form factor k from the diagram in the upper right corner.

Rectangular buffer/rail

Please enter the values for rubber height, width and length of your rectangular buffer/rail in the following fields to have the form factor k calculated.

Read the value for the modulus of elasticity (Ec) as a function of the form factor k from the diagram in the upper right corner.

Ec depending on k

Please read off the value for the modulus of elasticity Ec from the following diagram after the form factor k has been calculated (see left).
