Reliable chain adjustment for ANSI 50-1 drives

Practical benefits
  • Accurate chain length adjustment: You easily adjust odd numbers of pitches in your roller chain assembly using this double cranked link.
  • Dependable high breaking strength: With a breaking load of 21800 N, you maintain safe and continuous power transmission under demanding loads.
  • Standardized simplex chain fit: The exact 15,875 mm pitch lets you integrate the component smoothly into compatible ANSI drive setups.

In a nutshell

The right choise for

With the Renold Blue 50A1S30I double cranked link, you quickly and reliably adjust drive chains without replacing the entire chain assembly. Specially designed for ansi 50-1 simplex roller chains with a 15.875 mm (5/8 inch) pitch, this link number 30 component allows you to accurately connect odd numbers of pitches and achieve proper chain tension. Thanks to a dependable breaking strength of 21800 N, you maintain safe and stable power transmission across industrial machinery and conveyor systems. Featuring a roller diameter of 10.16 mm and a pin diameter of 5.08 mm, it integrates smoothly into your routine maintenance and repair tasks.

Product description:

  • Conveyor chains, like roller chains, can be made to different international standards. The main standards are:

    British Standard (BS):

    • This standard applies to chains made for the British market and for markets where British presence has had a major influence on technical design and buying behaviour. This standard is based on Renold's original conveyor chain design.

    ISO Standard chains:

    • Chains made to the ISO Standard are not interchangeable with chains made to the BS or DIN Standard.
    • This standard is widely used in the European market, except in Germany.
    • Chains made according to this standard are becoming increasingly popular and are widely used in Scandinavia.
    • Renold has a lot of experience in producing conveyor chains.
    • Renold's conveyor chains are based on many years of design and development, allowing us to deliver the optimal product.
    • To ensure that this quality is reflected in the performance of our products, we carry out strict checks on:
      • Materials
      • Heat treatment
      • Processes
      • Fittings
      • Attachment assembly
      • Lubrication
      • Conveyor Chain Exploded View

    Ultimate Renold reliability:

    • The key to the reliability of Renold chains is consistency in design and manufacturing.
    • The chains' maximum strength and wear resistance are achieved by strictly controlling material specification and using state-of-the-art heat treatment processes.
    • The consistent overall tolerability of Renold chains makes them ideal for conveyor systems that require precise alignment of different chain mechanisms.
    • The breaking load is greater than the internationally required minimum.
    • For optimum performance, it is important to choose the right chain.
    • Renold's experienced design team is always at your disposal for free advice on specific products and applications.
    • Standard and Deep Link conveyor chains are available for BS4116 part 4 and for ISO 1977, with both hollow and solid pins.

    Extra strong standard conveyor chain:

    • Complementing our standard range of conveyor chains to British Standard, we offer this extra strong chain suitable for conveyor applications requiring ultimate tensile strength (breaking load).
    • Each chain has the same dimensions as its normal counterpart.
    • For example, an extra strong chain of 11,000 kilos (24000 lbs) has the same dimensions as a normal chain of 5500 kilos (12000 lbs).
    • This chain is frequently used to transport animal feed and unpackaged foodstuffs such as grain, corn, wheat and raw food mixtures.
    • Most of these applications use scraper conveyor systems with large spacing between sprockets. Such systems sometimes move slowly, with little or no shock loading.
