Welded-steel conveyor chain
Engineering-class welded steel chain (Permaweld) for heavy bulk-handling mill and drag conveyors, built with press-fit pins in punched side plates and welded bushes. Type W and Type WD construction gives tight dimensional control and a wide attachment range, with medium-carbon components that can be heat treated and case-hardened bushes for strength and wear. SES holds the range as an authorised Renold distributor, covering pins/plates Medium-carbon steel, heat-treatable; bushes Carburising grade, case-hardened; pin fit Press-fit into side plates to limit wear; type wd bushes Formed for capacity, shock and yield strength. Executions include type w (permaweld mill), type WD (permaweld drag), straight and cranked link, wide attachment options. It is specified most often into bulk material handling and cement and aggregate plant. 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 Welded-steel conveyor chain in the parts of a plant where this particular duty actually occurs. In practice that means bulk material handling, cement and aggregate plant, steel mills, and equally foundries, sawmills and wood yards, mining and quarrying. What links them is the duty rather than the machine name — class: Engineering / welded steel. 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. Heavy dragging load with shock — Type WD drag build with formed case-hardened bushes General mill conveying — Type W Permaweld cranked-link chain Severe abrasion at high temperature — Heavy-duty hard-faced drag chain instead 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.
Made-to-order engineering chain, not shelf stock — quote by pitch, series and attachment against the customer's conveyor drawing. Send the designation off the failed part and we will confirm the Renold equivalent and stock position.
