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.
