KCM 40NL ASA Self-Lube Roller Chain Simplex, 1/2 in Pitch, 10 ft Box

ASA self-lube simplex roller chain from KCM. Oil-impregnated bushing gives self-lubrication, so no relubrication is needed.

AIMS Industrial supplies it in boxed lengths of 10 ft (3.05 m). This listing covers 3 sizes (40NL, 50NL and 60NL). KCM's published dimensions and strength figures for each size are in the table below.

Where this product is used

• Drives where no lubrication is allowed
• Drives where lubricating in the process is difficult
• Hard-to-reach chain drives

Features

• Oil-impregnated bushing gives self-lubrication, so no relubrication is needed
• KCM recommends chain speeds of 150 m/min or slower
• Operating temperature range -10 to +150 degrees C
• Pin is longer than standard chain because the inner plate is thicker

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 self-lube chain where lubrication is not required or is hard to carry out. KCM says to select it from its chain power transmission table, not by the low-speed selection method. Single strand chain runs on standard sprockets; multiple-strand chain needs an exclusive sprocket.

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.
