The Diamond S series roller chain is a power transmission component made up of plates, pins and rollers that mesh with sprockets to transmit motion between shafts in a synchronized way. It is used in equipment that requires positive drive, good tensile strength and continuous operation, from production machines to conveyors and industrial drive systems in plants in Buenos Aires, Argentina and throughout the country.
The S series designation is read by its number: S25, S35, S40, S41, S50 and their variants. The number indicates the ANSI/ASME pitch of the chain, and the -2 or -3 suffix indicates whether it is double or triple strand. Thus, S40 is single, S40-2 is double and S40-3 is triple. The pitch and the number of strands define the width, the load capacity and the compatible sprocket. Send the complete part number so we can quote it for you.
In Argentine industry these chains appear in roller conveyors, elevators, bagging machines, mixers, blowers, packaging lines and material handling equipment. They are also used in the food, chemical, ceramic and metallurgical sectors, where positive drive and synchronization between shafts are critical. The Diamond Sapphire series covers small and medium pitches for these applications.
To select correctly, take into account the pitch, the number of strands, the power to be transmitted, the speed and the working environment. In places with dust, moisture or washing, it is advisable to evaluate lubrication and protection; in fixed drives, sprocket alignment and correct tension extend the life of the assembly. Mounting requires sprockets of the same pitch and a check of runout and parallelism between shafts.
ANSI/ASME roller chains are interchangeable between brands by their pitch and number of strands: an S40 single chain can be replaced by another of the same pitch and configuration. The differences are usually in the treatment of plates, pins and rollers, and in fatigue resistance. If you bring the part number of another brand or a sample, we will tell you the compatible equivalent.

Frequently Asked Questions
- What does the -2 or -3 suffix mean on an S40 chain?
- The suffix indicates the number of strands: S40 is single, S40-2 is double and S40-3 is triple. The more strands, the greater the transmission capacity for the same pitch. Provide the complete part number when requesting a quote.
- How do I request the chain I need?
- Message us on WhatsApp with the chain part number or the pitch and number of strands. We will quote the exact reference and, if needed, advise you on the compatible sprocket and lubrication.
- Which sprocket goes with an S series chain?
- The sprocket must have the same ANSI/ASME pitch as the chain and the number of teeth suitable for your transmission ratio. Send the chain part number and we will tell you the compatible option for your equipment.
