This is one of the most popular reciprocators used in multi-needle embroidery machines. This is the reciprocator only, which is the part that generally wears out or breaks on the reciprocator assembly.
This component can be fitted on the following machines according to the documentation available. However, manufacturers often change components on the same model number across serial numbers. Please compare the images to the reciprocator on your machine to make sure it matches. The jump bar (the long post on the side) is 2 inches long.
