ABSTRACT:
An improved chain, compatible with food grade lubricants, is capable of use in poultry and other meat processing facilities. The chain comprises pairs of side links alternating with center links, and held together with pins. A pair of lubricating wells is located on each side link, proximate the insertion point of the pins. The lubricating well provides lubricating access to the pins, and is capable of retaining lubricant such that lubricant is continuously provided to the pins and their pivot points throughout the operation of the chain.
