SY 40-1 SLR-TS Self-Lube ASA Simplex Roller Chain, 1/2 in Pitch, 10 ft Box

SY ASA (ANSI) simplex roller chain from Sugiyama Chain Co., Ltd. SLR series chain carries its own lubricant in sintered, oil-impregnated bushings and is lubricated before delivery.

Made in Japan by Sugiyama Chain Co., Ltd. AIMS Industrial supplies it in boxed lengths of 10 ft (3.05 m). This listing covers 4 sizes (40 to 80), and the table below carries Sugiyama's published dimensions and strength figures for every size.

Where this product is used

• Drives and conveyors where regular relubrication is difficult
• Dry, clean-running machinery below about 70 °C
• Hard-to-reach chain drives

Features

• Lubricant held in oil-impregnated sintered bushings, in the pin and bushing contact area
• Black-oxide coated plates
• Lubricated before delivery
• Made in Japan by Sugiyama Chain Co., Ltd
• Dimensions and strength figures taken from Sugiyama's published tables

Selecting the right option

For ASA (ANSI) 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 SLR where relubricating is impractical. Sugiyama lists this ANSI size as SLR-TS, the self-lube chain for drives, which has the same strength as standard carbon steel chain and a longer pin length than SBR, so check clearances. Keep it away from water, chemicals and shock loads.

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

Fitting and use

Tensile strength is the load at which the chain breaks in a single pull and is not a working load. Sugiyama's rule of thumb is to 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.

Service life drops sharply if the lubricant in the bushings is depleted, and the lubricant seeps out quickly above about 70 °C operating temperature.

Wet or dusty environments can lead to premature wear. Sugiyama does not recommend SLR chain where it is exposed to chemicals, water or shock load.

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.
