Heavy Duty Lambda Chain NP Series

NP Series Heavy Duty Lambda Chain

NP Series offers plates and rollers with a special nickel plating for light corrosion resistance

Special sprockets required.

We reviewed the material and processing that go into our special oil-impregnated bushes, and improved the lubricant, giving it more than twice the wear life over previous products.


Achieves the same strength as standard roller chain
Achieves the same strength as RS Roller Chains, even with double-strand chains, by increasing the thickness of the outer and inner plates by one size.
Attractive appearance, light corrosion resistance
Plates and rollers have a special nickel plating for an attractive appearance and light corrosion resistance.
Improved the lubricant used in the special oil impregnated bushes.
