What is the purpose of this double offset link?

This double offset link (No. 30) allows you to adjust a chain with an odd number of pitches or connect two inner links securely.

Which chain type is this link compatible with?

It is designed for standard 16B-1 simplex roller chains conforming to BS and ISO standards with a 25.4 mm (1") pitch.

What are the main dimensions of this link?

It features a pitch of 25.4 mm, an inside width of 17.02 mm, a roller diameter of 15.88 mm, and a pin diameter of 8.28 mm.

What is the breaking strength of this chain link?

This link from the Renold Blue range offers a minimum tensile breaking strength of 60000 N (60 kN) for demanding drive applications.

What is the advantage of a double offset link over a single offset link?

A double offset link combines an offset link and an inner link into a single unit, providing greater structural stability in the chain.

Reliable chain adjustment with Renold Blue

Practical benefits

Exact chain length adaptation: You easily adjust roller chains with an odd link count thanks to the precise 1" pitch geometry.
High breaking load strength: With a tensile breaking strength of 60000 N, you handle demanding drive loads safely and consistently.
Smooth and durable transmission: The 15.88 mm hardened rollers and reinforced plates keep your drive system running smoothly under heavy work.

In a nutshell

The right choise for

With the Renold Blue 16B1S30I double offset link, you easily adapt roller chains with an odd number of links. This simplex link (No. 30) is engineered for standard 16B-1 roller chains with a 25.4 mm (1") pitch, a 15.88 mm roller diameter, and an inside width of 17.02 mm. By combining an offset link and an inner link into a single pre-assembled unit, it provides a rigid connection and smooth drive transmission. With a tensile breaking strength of 60000 N, it handles heavy mechanical loads reliably in industrial drives and conveyor systems without requiring a full chain replacement.

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.
