K48kæder

K48kæder is a Danish term used to describe a family of heavy-duty roller chains employed for power transmission and material handling in industrial settings. The designation K48 is used by several manufacturers to identify a chain with a relatively large pitch and robust construction, suitable for high-load applications, such as conveyors, agricultural equipment, and packaging lines.

A K48kæde typically consists of inner links, outer links, rollers, pins, and bushings assembled into a continuous loop. The chains are produced in various materials, most commonly carbon steel, alloy steel, or stainless steel, and may be zinc-plated or galvanized to improve corrosion resistance. Variants include standard roller chains and reinforced versions with thicker plates or strengthened pins.

Performance depends on pitch (the distance between adjacent pins), the width of the chain, and the materials used. Selection factors include load per link, operating speed, environmental conditions, lubrication, and required durability. In use, proper lubrication, tensioning, and alignment are essential to reduce wear and elongation and to prevent premature failure. Regular inspection should monitor wear on pins, bushings, and rollers and check for stretching beyond manufacturer guidelines.

K48kæder are typically governed by general roller chain standards rather than a unique Danish specification. Industry catalogs and distributors provide model-specific data covering dimensions, tensile strength, and compatible sprockets. See also Roller chain, Conveyor systems, Chain maintenance.
