Abstract
A rail-bearing for the shuttle in a shuttle type sewing machine in which the shuttle housing is provided with a circular rail formed to mate with a circular groove in the shuttle. This rail-groove combination is so arranged as to deter jamming of the shuttle by thread or errant bits of debris. This rail-bearing has inherent high speed capabilities and is easy to lubricate and to manufacture.
