Key specifications

Choosing the right option

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

SBR is the standard choice for most drives and conveyors. Step up to H, HE or SUP H where loads are heavy or shocked, or to Aqua-Proof, stainless steel or self-lube chain where the environment calls for it.

ASA and BS chain of the same pitch are not the same: for example 12.7mm pitch ASA 40 has a 7.95mm roller width and 7.92mm roller, while 12.7mm pitch BS 08B has a 7.75mm roller width and 8.51mm roller (Sugiyama SBR tables). Match the chain to the sprocket standard.

Tensile strength is the load at which the chain breaks in a single pull and is not a working load. As a rule of thumb, never load roller chain above 50% of its ultimate tensile strength, even for one cycle, and to apply the multiple-strand factor to multiple-strand chain.

Lubrication guide: manual lubrication below 15 m/min chain speed, drip lubrication from 15 to 30 m/min, and oil bath from 30 m/min.

Where a single-pitch offset link is used, the load figures allow for a 35% reduction in fatigue strength.

Chain drives should be guarded. Lock out machine power before removing, installing or servicing chain, wear eye protection when driving or grinding pins, avoid welding or plating assembled chain, and never repair damaged chain by replacing only some of its parts.
