Welded Steel Mill Chain - WR111PLUS - Connecting Link
Welded Steel Mill Chain (Offset Side Bar)
Designed to replace cast steel chains and offer a higher strength and lower wear rate. These chains can accommodate a wide array of attachments and are commonly found within the wood and paper processing industries where there are demanding conditions.
The offset/crank link design allows the chains to be easily lengthened, shortened or repaired when required.
WR – Welded steel chain – offset style with through hardened pins and case hardened bushes.
WH – Welded steel chain – offset style with all components fully heat treated.
Welded Steel Mill Chain (Offset Side Bar)
Welded steel mill chains have an offset or cranked link and are an extremely versatile bush only chains which are usually used in abrasive and tough applications, often elevating and conveying. They offer an extremely tough rollerless chain, with the bushes secured to the link plates by fully welding around the bushes on the inside face of the link plates, which prevents the bushes becoming loose and rotating over time. With various heat treatment regimes available along with a wide array of standard and nonstandard attachments, these chains offer a cost-effective solution in many mill, bulk handling and washing applications.
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.
