Sizing Industrial Shock Absorbers for
Motor Driven Mass
When a moving mass is driven by a motor, correct industrial shock absorber selection becomes even more important to handle higher speeds and greater kinetic energy. At Shockbuffer, we offer expert sizing of shock absorbers for motor-driven loads to ensure safe deceleration, protect equipment, and prevent vibration and shock-related damage. Our mid-size industrial shock absorbers are specifically designed to slow down motorized movements smoothly, improving machine reliability and extending component life. Choosing the right shock absorber for machinery keeps production lines efficient and helps reduce maintenance costs.
Formulae
E1 = W · v · 0.5
E2 = (1000 · Pm · ST · s)/v
E3 = E1 + E2
E4 = E3 · c
vD = v
We = (2 · E3 )/vD

Example: Sizing Industrial Shock Absorbers for Motor Driven Mass
W = 500 kg
v = 0.5 m/s
ST = 2.5
Pm = 5 kW
c = 100 /hr
s = 0.050 m
E1 = 500 · 0.5 · 0.5 = 62.5 Nm
E2 = (1000 · 5 · 2.5 · 0.05) /1.5 =1212.9 Nm
E3 = 62.5 + 1212.9 = 1275.4 Nm
E4 = 1275.4 · 100 = 127540 Nm/hr
We = (2 · 1275.4) / 0.5 = 10202.8 kg

Applications of Industrial Shock Absorbers
Typical shock absorber applications in this category include:
-
Automated linear transfer units and shuttles driven by servo motors
-
Rotary indexing tables that rotate quickly and stop precisely at fixed positions
-
Pick-and-place robots and gantry robots with motor-driven axes
-
Packaging machines where driven slides move products at high speed
-
Automated assembly equipment with powered movement of tooling or parts
-
Motorized sliding doors or gates that must decelerate safely at end of travel
In all these cases, a mid-size industrial shock absorber must be carefully sized to match the driven mass, velocity, and cycle rate—absorbing the kinetic energy efficiently to protect machinery and ensure smooth operation.
