200mm Pitch Block And Bar Chain Connecting Link NF 40200 - 397kN
NF Block and Bar Chain
Bar link conveyor chains or block and bar chains are used for heavy duty applications or within tough environments. Generally supplied with a range of attachments, outboard rollers, through pin lubrication and special lubrication bushes. Most bar link conveyor chains are manufactured to suit our customers requirements, but a general range is shown here.
NF Block and Bar Chain
Block chain, block and bar chain or bar and pin chain is particularly well suited for heavy load, high fatigue, elevated temperature and abrasive applications. In its simplest form the chain consists of two outer link plates and an inner block connected by a pin. This simple form of chain is shown here.
The ‘block’ part of the conveyor chain can be changed to a simple pusher for moving a trolley through a car paint line through to a heavily engineered block with side rollers, tilting dogs, self-lubricating bushings and lubrication ports for cooling steel ingots.
As block and bar chains are generally engineered to suit a specific application, please contact one of our engineers to discuss your requirements. We can manufacture block and bar chains to our customers specifications, design new chains for new applications and offer sprockets to suit all of the chains that we manufacture.
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.
