6" Pitch Engineered Steel Bush Chain - S859
Engineered Steel Bush Chains
High strength bush chain which is generally used in abrasive environments as either an elevator or scraper chain for bulk materials. A range of attachments and coatings are available for either our standard range or to suit our customers requirements. We can also manufacture special chains if required. Sprockets can also be supplied to suit all chains within this range.
Engineered Steel Bush Chains
Engineered steel bush conveyor chains, which can also be known as steel knuckle chains are a wide width bush only chain. The lack of a roller, increased contact area between the pin and the bush and lighter weights generally sees them applied to elevators and conveyors operating in harsh or abrasive environments, with infrequent or minimal lubrication. One industrial example would be Cement plants.
These wide series engineered steel bush chains are a more durable version of cast combination chains and are often interchangeable. Although straight link plate versions are shown here, cranked or offset link versions are also available upon request.
Challenge also offer nonstandard sizes and materials, a full range of attachments and fabricated sprockets to compliment the range of engineered steel bush chains.
Challenge S102B-C Extra Plus
Many of our customers have asked us to improve upon the standard S102B chain that they have purchased from other suppliers. Although we still offer S102B in its standard form, over 90% of the S102B chain that we supply is to the Challenge Extra Plus standard which includes the following benefits;
• 40x10mm Heat Treated (Normalized) link plates, offering a 20% increase in breaking load to 210kn and a more uniform link plate material with increased toughness.
• Extended wear life which is achieved by carefully controlling our material quality and heat treatments. We also grind our round parts to ensure the strictest tolerances and best possible wear surfaces.
• Interchangeable with standard S102B for easy installation.
• Covered by our Lifetime Guarantee (as are all of our products).
We work hard so that your conveyor chain can too - Premium Manufacturing as Standard
All our conveyor chains are manufactured using the very latest manufacturing technology and techniques. With fully punched and shot peened link plates, CNC machined components, precision component fits, in house heat treatment, fully ground round parts and heavy-duty spin riveting, our standard is designed and proven to outperform other leading brands.
Cropped links from medium carbon steel
Our link plates are precision punched from cold drawn steel. Not only does this limit internal stress, but it also provides a precision hole pitch and increased tensile strength due to grain alignment.
Shouldered or flatted case-hardened bushes
Inserted with a press fit to prevent rotation and produced from on-size chromium-molybdenum seamless tube for minimum distortion, superior concentricity and maximum strength.
Shouldered or flatted case-hardened pins
Secured with a press fit and spin riveting. Selective in-house induction hardening allows deep case depth on wearing surfaces without stressing/cracking the pin ends during assembly and riveting.
Hardened and ground Precision Rollers
Through hardening and a light grind after heat treatment ensures a dimensionally accurate roller with a good hardness even after wearing during operation.
ISO 9001 and full traceability
Strictly manufactured to ISO 9001 with quality checks at every stage of manufacture. Our chains are fully traceable back to their original materials, which are also independently tested upon delivery.
Our Standard range and above features cover; British Standard (Z) Series, M Series and FV Series
Whatever your requirements, we have all the options covered
There are a wide array of nonstandard and heavy-duty conveyor chains used throughout industry today. These chains are often developed to offer extended service lives, increased strength, enhanced reliability and operational speed or perform special duties within the industries that they serve. Challenge has well recognised experience in many of these industries, including;
• Palm Oil
• Timber and Paper
• Steel manufacturing
• Waste and Recycling
• Bulk Material Handling
• Water Treatment
We can cater for a wide range of special requirements, which includes but is not limited to;
• Plasma nitride hardened pins and bushes
• Stainless steel (all grades)
• Sherardized plates and attachments
• Molykote dry lubricants
• Hot dip glavanizing
• Zinc/nickel plating
• Food grade oils
• Nonstandard chain pitches
Sprockets to suit our entire conveyor chain range
Transmission and Conveyor chains are driven by sprockets. The even distribution of power relies on accurate gearing between the sprocket teeth and the chain rollers or bush.
As sprockets greatly affect the life of the chain, all Challenge sprockets from cast through to precision machine cut are manufactured to strict tolerances and quality controls. We also advise all of our customers to replace their sprockets whenever a chain is replaced in order to maximise the chains life.
All lengths/coils of conveyor chain are supplied with a standard connecting link on the end of each length or coil.
