ABSTRACT:
A relatively low cost, low friction plastic needle bearing assembly uses a unitary plastic circular member with multiple frangibly attached substantially cylindrical needles axially inserted into a cover. A plastic needle separator housing element provides a race and is in axial registration with the frangibly attached needles. A shaft (on which a sprocket of a web feed device or tractor is mounted), upon axial insertion through the member to which the needles are attached, frees the multiple needles from the frangible attachment to the member and ejects the member from the cover leaving the needle bearings captured by the race in the cover.
