OLI Rotary Roller Vibrators OR

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.

OLI Rotary Roller Vibrators OR

With OR-series Roller Vibrators vibration is generated by the movement of rollers inside an eccentric guide. OR generate low amplitude and high frequency vibration. Among others, they are suitable for concrete compacting tables, foundry moulds and hopper emptying due to higher force generated than by ball-type S-series vibrators.

The OR-series, which comes with a black aluminium casing and brass cover, is available in four different sizes.
Operating with oiled air at 2 to 6 bar (29 ~ 87 PSI), the OR-series is suitable for application in explosive environments (ATEX EX II 2DG cT(x)). Operating noise reaches 90 dB(A).
