Reliable drive linking with Renold Synergy

Practical benefits

High breaking load capacity: With a 17800 N breaking load, you reliably transfer demanding drive forces without risking link failure.
Precise pitch and fit: The standard 12.7 mm pitch and 7.75 mm inner width ensure seamless operation on 08B-1 simplex chains.
Resilient heavy-duty construction: Robust 1.55 mm thick plates provide you with dependable fatigue resistance during continuous mechanical use.

In a nutshell

The right choise for

With the Renold Synergy GY08B1S30I double cranked link, you can easily close your 08B-1 roller chain whenever an odd number of links is required. During maintenance and repairs on conveyor systems or machinery, it eliminates the need to replace the entire chain, saving you valuable time. Thanks to the 17800 n breaking load and durable 1.55 mm thick plates, you reliably transfer demanding drive forces under heavy use. Featuring a standard 12.7 mm pitch and an inside width of 7.75 mm, this link fits seamlessly to ensure smooth and wear-resistant operation.

Product description:

Renold Synergy - Made to be better:

The Renold Synergy has an outstanding reputation as the only, true high-performance roller chain on the market.
This reputation is based not only on the years of research and testing that preceded its design, but also on the feedback from engineers around the world who have experienced and endorse the wear resistance, fatigue resistance and exceptional longevity of the Renold Synergy themselves.

Improved fatigue resistance:

The design of blade and connector optimises pressure distribution and fatigue performance.
The Renold Synergy performs, on average, 30 per cent better than other brands under repeated shock loads and continuous heavy loads.
Fatigue Comp

Better wear resistance:

Independent tests show that the Renold Synergy performs up to six times better than the competition's highest performance chain.

Made to perform:

Every part of Renold Synergy precisely engineered using state-of-the-art development methods such as Finite Element Analysis (FEA). It all contributes to chain performance that is more than the sum of its parts.

Wide range of sizes:

Renold Synergy chain is available in British Standard dimensions from 06B to 24B in simplex, duplex and triplex construction. In addition, ANSI Standard sizes are available from 35 to 160 in simplex, duplex and triplex construction.

Scale shape:

High blade profile for improved stress distribution; maximised blade thickness within the limitations of the standard.

Bushings:

Solid extruded bushings deliver improved roundness and strength compared to rolled bushings. Chamfered ends improve the bearing section and extend service life.

Hole quality:

'Triple punch holing' techniques ensure correct pin and bushing position for even wear.

Fixed fit:

Optimised to ensure maximum service life.

Fatigue resistance:

Prestressed surfaces increase fatigue resistance.

Wear resistance:

Chamfered parts and special surface coating of the pin increase wear resistance.

Connecting link:

Has a unique design that ensures that all parts of the chain system are equally strong.
