KCM 40SB ASA Side Bow Roller Chain Simplex, 1/2 in Pitch, 10 ft Box
Available
ASA side bow simplex roller chain from KCM. Bows sideways, so the chain can run around horizontal curves on standard sprockets.
AIMS Industrial supplies it in boxed lengths of 10 ft (3.05 m). This listing covers 3 sizes (40SB, 50SB and 60SB). KCM's published dimensions and strength figures for each size are in the table below.
Where this product is used
- Curved-track conveyors
- Conveyors with horizontal bends
- Chain that must flex sideways
Features
- Bows sideways, so the chain can run around horizontal curves on standard sprockets
- KCM lists a minimum horizontal bending radius for each size (350 to 600 mm)
- Attachments can be fitted to build curved conveyors

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 side bow chain where the chain has to curve in the horizontal plane. Keep the curve radius at or above the minimum horizontal bending radius for the size.
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.
