Our #50 Roller Chain is made of high quality carbon steel and meets or exceeds all ANSI/ASME standards for durability. Pre-stressed and manufactured with solid rollers, you’ll be pleasantly surprised by the long life and strength of our industrial and premium roller chains. All chains are pre-lubricated with high quality wax-type grease and come with a necessary connecting link to join the ends. Offset links (used to shorten or lengthen a chain strand by 1 pitch) are also available and sold separately. This chain is packaged in a 10ft box. Industrial and Premium Grades are available.
