AIMS Industrial supplies it in boxed lengths of 10 ft (3.05 m). This listing covers 4 sizes (08B-16B). KCM's 2017.04 catalogue does not publish dimensions or strength figures for this type, so only the chain number and pitch are listed here.

Features

Key specifications

Available sizes

Selecting the right option

For BS chain the number is the pitch in sixteenths of an inch: 08B is 8/16 in (1/2 in), 12B is 12/16 in (3/4 in), 16B is 1 in. The figure after the dash is the number of strands.

KCM's 2017.04 catalogue does not cover X-ring chain, so no dimensions, strength or temperature figures are shown here. Ask AIMS for the manufacturer's data sheet if you need them before ordering.

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.
