OLI – OR – Pneumatic Rotational Vibrators – Roller

In the OR series, high frequency vibration is generated by a roller that describes an epicycloidal movement inside two housings made of hardened and ground steel. The OR series is characterized by high speed, great centrifugal force (up to 783 kg) and low air consumption.

Categories: ,


OR rotational roller vibrators are used on silos, hoppers, pipes and chutes, as well as in compacting concrete.
The installation does not require drilling the walls of the application, for this reason they are particularly suitable for integration on existing systems and machinery.


The body of the OR series products is made of anodized aluminum while the covers are made of brass.
Lubricated air supply is required, with operating pressures from 2 to 6 bar (29 ~ 87 PSI). Noise at full speed does not exceed 90 dB (A).
The OR roller vibrator series consists of 4 sizes and able to operate in environments with temperatures up to + 200 ° C (+ 392 ° F).


  • High centrifugal force
  • Easy to install
  • Suitable for high temperatures
