Stainless SDss chain
A standard-duty stainless steel roller chain for wet, hygienic and chemically aggressive environments where carbon-steel chain would corrode. The enhanced SDss range spans 162 products across BS and ANSI in simplex, duplex and triplex, so a stainless option exists for most standard drives. SES holds the range as an authorised Renold distributor, covering bs sizes 04B to 32B; ansi sizes 25A to 160A; strands Simplex, duplex and triplex; range 162 products. Executions include 04b–32b british standard, 25a–160a ANSI, simplex, duplex, among others. It is specified most often into pharmaceuticals and canning and bottling. 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 Stainless SDss chain in the parts of a plant where this particular duty actually occurs. In practice that means pharmaceuticals, canning and bottling, food and drink processing/packaging, and equally water and wastewater treatment, chemical processing, paper/pulp and textiles. What links them is the duty rather than the machine name — material: Stainless 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. Acidic, alkaline or wash-down environment — SDss stainless for corrosion resistance Non-magnetic or hygienic requirement — SDss stainless grade Corrosion resistance wanted at lower cost / higher strength — Hydro-Service treated carbon 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.
Stainless is lower tensile than carbon chain of the same pitch — size on breaking load, not pitch, and flag that to customers switching from SD. Send the designation off the failed part and we will confirm the Renold equivalent and stock position.
