Sizing Industrial Shock Absorbers for Rotary Index Table Without Drive Torque
Rotary index tables sometimes rotate under the momentum of the load itself rather than an active drive torque, yet still build enough kinetic energy to require careful damping. At Shockbuffer, we provide specialized industrial shock absorber selection and accurate sizing of shock absorbers for rotary index tables without drive torque, helping prevent uncontrolled stops and mechanical damage. Our medium industrial shock absorbers are engineered to handle these passive rotational motions, delivering smooth deceleration, reducing vibration, and protecting machinery. Choosing the right shock absorber for machinery ensures precise stopping, improved safety, and longer equipment life.
Formulae
E1 = W · v · 0.25
E2 = 0
E3 = E1 + E2
E4 = E3 · c
Vs = (v · Rs) / RT
We = (2 · E3) / Vs

Example: Sizing Industrial Shock Absorbers for Rotary Index Table Without Drive Torque
W = 408 kg
v = 1.2 m/s
C = 100 /hr
Rs = 0.7 m
DT = 1.8 m
RT = 0.9 m
Vs = Vel.@ Rs (m/sec)
E1 = 0.25 · 1.2 · 408= 147 Nm
E2 = 0
E3 = 147,+ 0 = 147 Nm
E4 = 147 · 100= 14700 Nm/hr
Vs= ( 1.2 · 0.7 )/0.9 = 0.9 m/s
We = (2 · 147 ) / 0.9 = 363 kg

Applications of Industrial Shock Absorbers
Typical shock absorber applications in this category include:
Rotary tables that rotate freely and stop at mechanical end stops
-
Indexing turrets moved by inertia from previous operations
-
Tables that rotate under the load’s own weight rather than motor power
-
Light-duty pallet turntables in automated systems
-
Slow-moving manual or gravity-assisted rotary fixtures
-
Testing systems where parts rotate freely and must stop gently
In each case, a medium industrial shock absorber must be sized to absorb the kinetic energy of the rotating mass, providing safe, controlled stopping and protecting the machine from impact.
