Electromechanical Unbalance Vibrators supplied by KJN are used as drives on linear motion vibratory feeders and screens. They can also be used to facilitate material flow in storage containers such as bins and hoppers when certain conditions exist or when Air Vibrators are not possible.

The NAVCO® Magnetic mount and clamp on vibrators distributed by KJN are ideal for use where light duty vibration is needed in multiple locations. The MV vibrator has a magnetic mounting head as well as a ferrous mounting sticker pad so it can even mount on non-ferrous hoppers . The FV vibrator has a screw-clamping mount. The ST is a stud mount and the MP is a pin mount. Each model has several sizes available except the Magnevibe (one size only).
