Triple Eccentric Drive
The Triple Eccentric Drive (
see Figure 4 below
) used in the Innova Shakers employs
the same proven technology which has driven New Brunswick Scientific’s shakers for
over 30 years.
This drive mechanism utilizes a counterweight system to stabilize the rotary motion
produced during operation. When the workload moves in one direction, opposing
forces are generated to stabilize the shaker. This action will help eliminate the
problem of “walking” which may occur with less precisely balanced instruments.
Vibration is minimized and the life of the unit is extended.

2.8 Bearings
Innova shakers employ shielded lubricated ball bearings of the highest quality.
Shielded bearings minimize the generation of airborne particulates which may be
disadvantageous in clean rooms or controlled environment areas. These bearings
require no maintenance.
