SY 08B-1 SLR Self-Lube BS Simplex Roller Chain Offset Link (Half Link), 1/2 in Pitch

SY offset links (half links) let a length of self-lube BS simplex roller chain be made up with an odd number of pitches. Each size here matches the SY chain of the same number, so select the link with the same chain number, strand count and series as your chain.

Made in Japan by Sugiyama Chain Co., Ltd. AIMS Industrial supplies these links individually. This listing covers 4 sizes (08B to 16B). Where possible, choose a chain length with an even number of pitches so that no offset link is needed.

Where this product is used

• Drives and conveyors where regular relubrication is difficult

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.

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.

Fitting and use

An offset link is handy where the chain needs an odd number of pitches, but Sugiyama notes it is at least 35% lower in fatigue strength than the chain itself and recommends against it where frequent impact loads at high speed are involved. A two-pitch offset link is available for that duty.

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.
