Shaker Mechanism Photographs


M/RAD Mechanical Shakers are considered the most reliable of the industry. These versatile shakers are designed or a wide range of vibration applications; from design qualification, end product reliability testing and environmental stress screening. Shakers are available to satisfy swept sine, frequency dwell and combined temperature requirements with a choice of options to accommodate any budget. Twenty-six years of continued shaker design and innovation allows M/RAD to offer the largest selection of standard models. Custom shakers are also available for unique applications. Conformance to MIL-STD and commercial requirements is always guaranteed.


Reliability and Fatigue Mechanical Shaker: Vertical
Specifications

The M/RAD Mechanical Shaker with vertical motion is a two shaft machine with eccentric weights usually calibrated in inches. A vernier scale with 1/32 increments is provided with these models. Some shakers are provided with a scale clearly notated in 10 degree increments. Whichever your selection, all M/RAD Mechanical Shakers are provided with self-aligning spherical roller bearings, coil spring isolation and friction dampers to prevent large table specimen excursions during start and stop operation. M/RAD offers pneumatic isolation for applications requiring lower frequency isolation or remote leveling. M/RAD's vertical shakers have been supplied in sizes from 18 inches square to 120 inches square and may accommodate payloads up to 15,000 pounds.


Mechanical Shaker: Elliptical
Specifications

The least expensive shaker in M/RAD's product line, the elliptical shaker is a single shaft machine which generates motion in the vertical and horizontal directions to provide a simultaneous two axes vibration. For applications which may require more than single direction vibration, this shaker is an inexpensive alternative for production line environmental stress screening (ESS). This shaker features a heavy steel gauge welded base, variable speed drive adjustable between 15-60 Hz and a coil spring isolation system. As with all M/RAD shakers, a special foundation is not required so that any solid floor is suitable for machine operation.


Reliability and Fatigue Mechanical Shaker: Vertical/Horizontal
Specifications

This family of Mechanical Shaker offers both vertical and horizontal capability. These shakers are provided in either a three or four shaft configuration. The adjustment from vertical to horizontal motion is easily performed by changing the eccentric mass to mass vectorial relationship. Special tools are not required and change of axis may be completed in less than 10 minutes. All M/RAD vertical/horizontal shakers are equipped with PHASE-LOCK to eliminate the crosstalk which may be encountered due to the height of a product's center of gravity. M/RAD's vertical/horizontal shakers have been supplied in sizes from 24 inches square to 16 feet square and may accommodate payloads up to 35,000 pounds.
