The Lund A series roller chains for transmission are characterized by high strength and long-lasting fatigue resistance. The chains comply with ANSI standards and are interchangeable with any other chains that meet this standard. A series roller chains can be assembled into single-strand, double-strand, and multi-strand configurations to suit the transmitted power and different spatial arrangements. Experimental data indicate that chain wear is related to the choice of lubricating oil. In the initial stage of leaving the factory, Lund provides an anti-rust oil film on the surface, which offers long-lasting lubrication and friction reduction. The quality of Lund chains complies with the EU REACH regulations, making them more environmentally friendly.
