Attachment are links with one or more link plates or pins modified to perform a special function in conveying, timing, and other. There are various standardized attachments available with SY standard ANSI roller chain and double-pitch roller chain. Other types and variations to the standards can be supplied on a made-to-order basis.

BS and ANSI Standard Attachment Roller Chain

Standard: BS and ANSI

Pitch: Single

Double Pitch Attachment Roller Chain

Standard: ANSI

Pitch: Double

Side Roller Chain

The side roller chain may be staggered or parallel at any given spacing. Roller materials are available with carbon steel or low friction plastic.

Standard: ANSI

Pitch: Single and Double

Top Roller Chain

Top Roller Chain is based on ANSI roller chain with extra roller mounted on top of the chain. Top rollers are installed on the pins that connect SK-1 extended plates. The rollers may be carbon steel, stainless steel or low friction plastic.

  • Higher Maximum Allowable Load
  • Straight Sidebar Connecting Link
  • Longer Service Life
  • Superb Appearance


The Strongest Maximum Allowable Load

Astounding Maximum Allowable Loads

+30% Higher Fatigue Strength

– Higher safety factor is gained

– Downsizing to smaller chain is possible in some applications

– Cost Savings

Significantly longer wear life

Conventional split bushings deform into a barrel shape when side plates are pressed on, leaving only two-point contact area. SBR (Solid Bushing & Roller) chain has extremely cylindrical inside and outside bushing walls resulting in full contact to disperse bearing pressure. Less pressure ensures excellent wear resistance.

Up to 2-3 times longer wear life over curled brushings

The curled, split bushings have a seam where tiny space allows lubricant leakage resulting in shorter wear life. SBR has no seam resulting in lower bearing pressure allowing the bushings to retain lubrication resulting in much longer wear life.

Reliable performance

SBR is cold-forged from steel rod. Cold-forming process also works with the molecular structure (grain) of the steel running lengthwise in the bushings thereby increasing fatigue strength and preventing bushings from breakage. Premium SBR chains improve performance of transmission with lesser elongation for long period of time.
