SD chain
Renold's own standard-duty (economy) roller chain, manufactured in-house rather than bought in, for general drives that don't need premium wear life. It carries the full set of international standards and Renold's manufacturing features — cold-extruded rollers, multiple-hit plate holing and pre-stressing — at an economy price point. SES holds the range as an authorised Renold distributor, covering pitch range 6.35 mm (04B) to 63.5 mm (2.5 in); rollers Cold-extruded for wear performance; plates Multiple-hit holing, pre-stressed for tensile/fatigue; standards European BS, ANSI, DIN 8187/8188. Executions include 05b–20b british standard, 35–160 ANSI, simplex, duplex, among others. It is specified most often into general machinery drives and conveyors. 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 SD chain in the parts of a plant where this particular duty actually occurs. In practice that means general machinery drives, conveyors, agricultural equipment, and equally pumps and fans, OEM equipment, replacement / MRO. What links them is the duty rather than the machine name — duty: Standard / economy. 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. Lightly-to-moderately loaded general drive — SD as the cost-effective standard Drive near its rating or long-life critical — Step up to Synergy Corrosive or lube-free duty — Move to a corrosion grade or Syno 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.

The workhorse stock line — carry BS 08B/10B/12B/16B simplex deep with matching connecting links. Send the designation off the failed part and we will confirm the Renold equivalent and stock position.
