Ball Vibrators
K-8-K-36

Roller Vibrators
R-50-R-120

Roller Vibrators
DAR-2-DAR-7

Useful Suggestions
*Oil Quality:
For the T-,DAR-and FP-Vibrator s= Hydraulic Oils as per ISO VG5 with 5 cSt/40°C for example:
SHELL Tellus Oil C5 ESSO UNTO H5 BP ENERGOL HP5
MOBIL VELOCITE Oil No.4 Warning: Oil with other viscosity will reduce the frequency!

For T-,DAR-and FP-Vibrators use air line lubricator
chean, humid compressed air rust builds up over
a long period

For T-and DAR-Vibrators use water separator and air line lubricator.
oil contaminated
compressed air
silencer slowly clogs
up, pressure build up
loosens endplates
increased friction, reduced rpm ,
can stop unit
increased friction,
reduced rpm,
can stop unit
Use filter
dirt particles in
compressed air
as above, effect will be sooner risk of reduced power
due to blocking of inlet holes
bad working
conditions
Use filter
excessive side
amplitude
ball will go out of track and wear endplates increases wear between rotor and endplates increases wear between rotor and endplates Stiffen mounting plate or bracket to reduce amplitude
excessive radial
amplitude
ball will skip, wearing race good working conditions good working conditions Stiffen mounting plate or bracket to reduce amplitude
ambient
temperature
maximum
100 °C = 220
maximum
140°C = 280°F
maximum
200°C = 400°F
The limiting temperature ranges should be strictly observed
