Abstract
An X-link conveyor chain (10) having a center link (12) assembled to side links (14) by a pin (16) having lubrication grooves (22). Lubrication grooves (22) extend from first and second T-head ends (38) and (40) of the pin (16) which facilitate lubrication of the central portion of the pin (16). Alternatively, lubrication grooves (50) may be provided in first and second ends (24) and (26) of the center link (12). Lubrication grooves (50) may be provided either directly or as a slot (62) formed in bushings (18) which are received in the first and second ends (24) and (26) of the center link (12). A bushing (18) disposed in first and second ends (24, 26) of a center link (12) provides a renewable X-link conveyor chain which may be repaired by replacing the bushings (18).
