The Diamond Duralube LIVE roller chain is a power transmission chain from the Duralube line, designed to work in equipment where continuous lubrication is critical. It is used to drive shafts and mechanisms in industrial plants, production lines and agricultural machinery. MR Accesorios Industriales sells it in Buenos Aires, Argentina, and quotes it by WhatsApp according to the pitch and number of strands.
The designation of this series combines the nominal pitch with the letters DLR. In the examples, 40 DLR, 50 DLR, 60 DLR and 80 DLR indicate single-strand chains, while 40-2 DLR, 50-2 DLR, 60-2 DLR and 80-2 DLR correspond to the double-strand versions. The number identifies the chain pitch and the -2 suffix the number of strands. Duralube LIVE is the brand's line intended for applications where lubricant plays a key role in service life.
These chains are used in low and medium speed transmissions in industries such as food, cement, mining and agriculture. In Argentina they appear in conveyors, bucket elevators, mills, mixers and bottling equipment. Also in road machinery and in production lines that need robust transmission with predictable maintenance. The Duralube LIVE series is aimed at equipment where access for lubrication is limited or where extending service intervals is desired.
To select the correct chain, take into account the pitch, the number of strands, the number of teeth on the wheels and the center distance. Verify that the sprockets are aligned and in good condition, because worn teeth accelerate chain elongation. Adequate lubrication and periodic tension checks are key to service life. If the equipment works in a dirty or humid environment, choose the version with the treatment that corresponds to that condition.
Roller chains are identified by their pitch and number of strands, and different brands use equivalent designations for the same sizes. If you bring the part number of another brand or a sample of the chain, we indicate the compatible equivalent. The brand does not have to match: what matters is that the pitch, width and number of strands are correct for your transmission.
To request a quote for your Diamond Duralube LIVE chain, send the complete part number by WhatsApp, for example 60-2 DLR, or the pitch and number of strands you need. MR Accesorios Industriales responds promptly with the quote and the alternative that best suits your equipment. If you have doubts about the designation, write to us with the machine model and we will help you identify it.

Frequently Asked Questions
- What does the -2 suffix mean in a Duralube LIVE chain?
- The -2 suffix indicates that the chain is double-strand. For example, 50-2 DLR has two rows of rollers in parallel, which allows it to transmit more power than a single chain of the same pitch. If your original equipment uses single strand, the part number does not carry the -2.
- How do I know what chain pitch my machine needs?
- The pitch is measured between the centers of two consecutive rollers and is expressed in inches or in the standard number. If you do not have the data, send us a photo of the chain and the part number on the equipment plate. We will indicate the pitch and number of strands required.
- Can I replace a chain from another brand with a Diamond Duralube LIVE?
- Yes, as long as the pitch, inner width and number of strands match. Roller chains from different brands are interchangeable when they comply with the same size standard. If you send us the part number of the original chain, we will quote the Diamond equivalent.
