Feeder stroke is the distance the bowl surface travels in one complete cycle of vibration. This is measured from the forward, upward limit of the vibrating stroke to the downward, backward limit of the stroke. The operating stroke of EB-00 Parts Feeders ranges between .015 inches and .060 inches, depending on the size of the bowl and

For example, a unit with a 1" stroke would use a stroke plate with a 1″ diameter circle. With the unit in operation, two circles will appear when looking at the moving stroke plate. When the two circles are exactly tangent in the form of a figure 8; the unit is set to its proper natural frequency speed.

the vibrating speed of the feeder during the contact time t B and because the take-off point does not coincide with the highest horizontal speed, the product speed never reaches that of the vibrating speed. The achiev-able feeder throughput is different for each product and depends on the vibrating frequency and amplitude.
