Sizing Industrial Shock Absorbers for Cylinder-Driven Horizontal Rotary Load

When a horizontal rotary arm or mechanism is driven by a hydraulic or pneumatic cylinder, it creates quick rotational movement and kinetic energy that must be absorbed to prevent shock and protect machinery. At Shockbuffer, we provide precise industrial shock absorber selection and expert sizing of shock absorbers for these cylinder-driven horizontal rotary applications. Our miniature industrial shock absorbers are designed to manage fast, repetitive, small-scale rotations, delivering smooth deceleration, reducing vibration, and extending machine life. Choosing the right shock absorber for machinery is essential to ensure reliable, efficient, and quiet operation in automated systems.

Formulae

V = (A · K) / t

F = 0.78 · D · p · Rc / RS

E1 = 0.5 · W · V

E2 = F · S

E3 = E1 + E2

E4 = E3 · c

Vs = (A · RS) / t

We = (2 · E3) / VS

Example: Sizing Industrial Shock Absorbers for Cylinder-Driven Horizontal Rotary Load

D = 0.060 m

p = 550000 Pa

RC = 0.4 m

W = 410 kg

K = 0.70 m

RS = 0.50 m

A = 1.57 rad

t = 3 sec

s = 0.025 m

c = 100 / hr

V = ( 1.57 · 0.70) / 3 = 0.37 m/s

F =0.78·0.060 · 550000·0.40 / 0.50 = 1235 Nm

E1 = 0.5 · 410 · 0.37  = 28 Nm

E2 = 1235 · 0.0254 = 31 Nm

E3 = 28 + 31 = 59 Nm

E4 = 59 · 100 = 5900 Nm/hr

VS = (1.57 · 0.50) / 3 = 0.26 m/s

We = (2 · 59 ) / 0.26  = 1746 kg

Application of Industrial Shock Absorbers

 

Typical shock absorber applications in this category include:
 

  • Compact pivoting arms powered by cylinders for part positioning

  • Small rotary indexing units in assembly or inspection stations

  • Pneumatic or hydraulic cylinder-driven diverter arms on conveyors

  • Quick-acting horizontal gates or flaps guiding products on production lines

  • Testing rigs with cylinder-actuated rotating fixtures

  • Lightweight handling systems moving components sideways into place


In each case, a miniature industrial shock absorber must be carefully sized to handle the kinetic energy generated by the horizontal rotary motion, ensuring smooth stops and protecting delicate machinery from impact and excessive wear.
