Heavy-duty drag chain
A welded steel drag chain for the most severe abrasive and high-temperature conveying, such as hot clinker and hot lime drag conveyors running up to around 1000 degF. Special heat-treated, induction-hardened pins give fatigue life, and a bead of hard-face weld down both sides resists sliding wear against the trough. SES holds the range as an authorised Renold distributor, covering pins Special heat-treated, induction-hardened; wear resistance Hard-face weld bead on both sides; temperature Rated to approx. 1000 degF; construction Welded steel drag type. Executions include welded steel drag series, hard-faced variants, multiple pitch / strength classes. It is specified most often into hot clinker drag conveyors and hot lime conveying. Every part is genuine Renold through official channels, with designation, specification and options confirmed against your duty before it ships — supplied from Kolkata and our branch network, with breakdown cover that does not sit in an inbox.

Where it runs.
You will find Heavy-duty drag chain in the parts of a plant where this particular duty actually occurs. In practice that means hot clinker drag conveyors, hot lime conveying, cement plant, and equally ash handling, foundry and smelter duty, mineral processing. What links them is the duty rather than the machine name — duty: Severe abrasion + high temperature. If your installation is not on that list it matters less than you would think: the operating condition decides the specification. Send us the load, the speed, the running temperature and the environment it runs in, and we will match it to the right execution in the Renold range and confirm what is in stock.
Specify it against the duty.
Specification here follows the operating condition, not the catalogue. Material is hot and severely abrasive — Heavy-duty drag chain with hard-facing Sliding wear against the trough dominates — Both-sides hard-face weld bead Ambient bulk handling only — Standard welded-steel conveyor chain Where two of those apply at once, specify for the harsher of the two — under-specifying is what puts the part back on the bench a month later. Send us the duty and we will confirm the execution.
Ordering this from SES.
Very high wear item — sell with a realistic wear-life expectation and encourage the customer to hold a spare length; long lead engineered product. Send the designation off the failed part and we will confirm the Renold equivalent and stock position.
