Patent ID: 8771119

Claim:
A chain comprising: alternately connected inner link plate pairs and outer link plate pairs, each pair of inner link plates being connected together with two bushings, each pair of outer link plates being connected together with two pins inserted into adjacent bushings of adjacent pairs of inner link plates, wherein said chain has a lubricant composition adhered to surfaces of said chain, wherein the lubricant composition comprising a paraffin-based mineral oil comprising 95% to 80% by mass of the lubricant composition, the paraffin-based mineral oil being a liquid at room temperature; and a wax comprising 5% to 20% by mass of the lubricant composition, the wax being solid at room temperature and consisting of a first polyethylene wax having an average molecular weight in a range of 1000 to 8000, or a mixture of a second polyethylene wax having an average molecular weight of 3000 and a third polyethylene wax having an average molecular weight of 8000; wherein a penetration of the lubricant composition is in a range from 63 to 210 and a dropping point of the lubricant composition is in a range from 94° C. to 120° C., the penetration being obtained by measuring a depth to which a specified cone penetrates the lubricant composition according to the penetration measurement method for “greases (JIS K 2220).”
