Sizing Industrial Shock Absorbers for
Rotary-Driven Horizontal Mass Propelling Torque

When a horizontal mass is propelled by torque from a rotary actuator or motor, it generates significant kinetic energy that must be carefully controlled to ensure safe, precise stopping. At Shockbuffer, we provide specialized industrial shock absorber selection and expert sizing of shock absorbers for these torque-driven applications. Our medium industrial shock absorbers are engineered to handle the impact forces produced by propelling torque, helping protect equipment, reduce vibration, and ensure smooth operation. Choosing the right shock absorber for machinery keeps automated systems reliable, safe, and efficient.

Formulae

E1 = 0.5 · W · v

Vs = (v · Rs ) / K

F = P / vS

E2 = F · S

E3 = E1 + E2

E4 = E3 · c

We = (2 · E3) / Vs

Example: Sizing Industrial Shock Absorbers for Rotary-Driven Horizontal Mass Propelling Torque

W = 408 kg

K = 0.7 m

V = 1.2 m/s

Rs = 0.7 m

s = 0.050 m

C = 100 /hr

P = 745 W

E1= 0.5 · 408 · 1.2    = 294 N-m

Vs = (1.2 · 0.7) / 0.7 = 1.2 m/s

F= 745 / 1.2 = 621 N

E2 = 621 · 0.05 = 31 Nm

E3 = 294 + 31 = 325 Nm

E4 = 325 · 100 = 32500 Nm/hr

We = (2 · 325 ) / 1.2   = 451 kg

Applications of Industrial Shock Absorbers​

 

Typical shock absorber applications in this category include:

​

  • Horizontally pivoting arms driven by electric or pneumatic rotary actuators

  • Rotary transfer devices that move products quickly between conveyor lines

  • Torque-driven indexers repositioning pallets or fixtures in production cells

  • Fast-moving horizontal pushers or diverters powered by rotary drives

  • Small turntables on assembly or packaging equipment requiring gentle stopping

  • Testing rigs with horizontal elements rotating under applied torque

 

In each case, a medium industrial shock absorber must be sized accurately to absorb the kinetic energy created by the propelling torque, delivering controlled deceleration and protecting mechanical systems from shock and wear.
