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.
