Schaeffer's Moly Roller Chain immediately goes to work penetrating and lubricating pens, bushings and metal surfaces without attracting dust. Moly Roller Chain Lube forms a solid, longer lasting film that rejects abrasive particles and moisture. This protective layer is capable of withstanding pressures up to 500,000 psi and reduces friction for longer equipment life. Schaeffer's Moly Roller Chain Lube is formulated to lubricate high speed or medium speed roller chains found in automotive, industrial, farming, construction and mining applications.
