What is Chain Supply UK - CSUK?

BS & ANSI Roller Chains British Engineered Excellence Since 2005 UK manufacturer & supplier of British Standard (BS) and American Standard (ANSI) roller chains, shaft mounted gear units (SMGU/SMSR) & industrial drive solutions. Serving Mining, Food Processing, Agriculture & Manufacturing from Rotherham, South Yorkshire.

What chain types are best suited for underground mining conveyors?

For underground mining conveyors we recommend drop forged rivetless chains or heavy-duty welded steel chains. These offer tensile strengths of 300–600 kN and are designed to withstand high shock loads, abrasive material contact and the dusty environments common in coal and ore mining. We stock multiple pitch sizes from Rotherham with fast UK-wide delivery.

How often should mining conveyor chains be lubricated?

In abrasive mining environments, we recommend lubrication every 100–150 operating hours under normal loads. In particularly dusty or wet conditions (such as underground coal faces), interval should be reduced to every 60–80 hours. Automatic lubrication systems are strongly recommended for inaccessible conveyor runs. CSUK can advise on compatible lubricants including extreme-pressure (EP) greases approved for mining use.

Do you supply chains to BS or ANSI standards for quarrying equipment?

Yes. CSUK supplies both BS (British Standard ISO 606) and ANSI (ASME B29.1) roller chains and engineering class chains for quarrying equipment. Many quarrying conveyors and bucket elevators in the UK use BS-standard chains, whilst equipment from US or Canadian manufacturers may require ANSI-spec chains. We can cross-reference your current chain number and supply the correct standard.

What is the lead time for heavy-duty mining chains?

Standard roller chain and many engineering class chains are held in UK stock at our Rotherham warehouse and can be dispatched same-day or next working day. For very large bore drop forged chains or bespoke lengths, lead times are typically 5–10 working days. We offer emergency stock holding agreements for high-usage customers in the mining sector.

Can you provide chain for bucket elevators in aggregate processing?

Yes. We supply central chains, JKE series chains and mill chains specifically designed for bucket elevator applications in aggregate and mineral processing. These chains are engineered for vertical loading, shock resistance and resistance to fine dust ingress. We can calculate the correct chain specification based on your elevator capacity, bucket pitch and operating speed.

How do I calculate the correct chain size for a mining conveyor?

Chain selection for mining conveyors involves: (1) calculating the conveyor's running tension in kN, (2) applying a service factor for shock loading (typically 1.5–2.0 for mining), (3) dividing by the number of chain strands to get the load per strand, and (4) selecting a chain with a minimum breaking load at least 5–8× the working load. CSUK's engineering team offers free chain selection support — contact us with your conveyor dimensions, material, and duty cycle.
