Features

Key specifications

Available sizes

Selecting the right option

For ASA chain the number is the pitch in eighths of an inch: 40 is 4/8 in (1/2 in), 60 is 6/8 in (3/4 in), 100 is 10/8 in (1-1/4 in). The figure after the dash is the number of strands.

Choose stainless steel chain where corrosion, heat or cleanliness rules out carbon steel. KCM publishes a maximum allowable load only, and it is far lower than the same-size steel chain (for example 0.44 kN against 3.63 kN for size 40), so size the chain on that figure. KCM also lists a strengthened AS stainless chain with a maximum allowable load 1.5 times that of standard SS.

Fitting and use

Tensile strength is the load at which the chain breaks in one pull and is not a working load. Use the maximum allowable load for working loads and choose chain with the selection method in the KCM catalogue.

KCM's replacement guideline, based on measured elongation, is 1.5% where the larger sprocket has 60 teeth or fewer, 1.2% for 61 to 80 teeth, 1.0% for 81 to 100 teeth and 0.8% for 101 or more, where take-up is possible. With fixed shaft centres it is 0.5% to 0.7%.

Insufficient lubrication promotes wear of pins and bushings, which leads to elongation. KCM says to lubricate the clearances between inner and outer links and between the rollers and inner links.

KCM says not to replace damaged parts of a chain with new ones. Replace the whole chain, and check the sprockets when changing chain.

Check that a safety cover is fitted before running a chain drive.
