The Diamond NP series roller chain is a power transmission component used to link shafts and transmit motion between sprockets. It is used in a wide variety of industrial machines, from conveyors to production equipment. MR Accesorios Industriales sells this line for the Argentine market, with technical advice to choose the right chain according to the application.
The NP series designation is read with a number indicating the chain pitch, followed by the letters NP. For example, 25NP, 35NP, 40NP, 50NP, 60NP, 80NP, 100NP and 120NP correspond to different pitch sizes. The higher the number, the greater the pitch and, in general, the greater the transmission capacity. The NP suffix identifies this particular line within Diamond's offering. To select the correct model, it is essential to know the pitch and the type of sprocket it will work with.
These chains are used in industries such as food, metallurgy, cement, mining and agriculture, among others. In Argentina, they are commonly found in material conveyors, machine tools, packaging equipment and transmission systems in manufacturing plants. Their robust construction makes them suitable for demanding environments, with the presence of dust, humidity or variable loads. MR Accesorios Industriales sells them to supply both workshops and large industrial plants.
To correctly choose a roller chain, take into account the pitch, the number of strands, the roller type and the working environment. If there is exposure to dirt or humidity, it is advisable to evaluate options with sealing or specific lubrication. Assembly requires aligning the sprockets and verifying proper tension to avoid premature wear. Periodic lubrication is key to extending service life. If space is limited, it may be necessary to opt for finer pitch chains.
Roller chains from different brands can be interchangeable if the pitch, inner width and roller diameter match. However, it is not enough for the pitch to be the same: the standardized dimensions must be verified. Diamond is a recognized brand in the market, and its products usually have equivalents in other firms. If you have the code of another brand, we can help you find the corresponding Diamond chain. It is always advisable to confirm the measurements before replacing a chain.
If you need a quote for a Diamond NP series roller chain, write to us on WhatsApp with the code or the measurements you require. At MR Accesorios Industriales we give you a prompt response and advise you so that you choose the right option for your equipment. We can also guide you if you are looking for a specific variant within the line.

Frequently Asked Questions
- What does the number mean in a Diamond NP series chain?
- The number indicates the chain pitch: the higher the number, the greater the pitch. For example, 40NP has a smaller pitch than 80NP. The NP suffix identifies the line. To select, compare the pitch with that of the existing sprocket.
- How do I know which chain replaces the one I have?
- Measure the pitch (distance between roller centers), the inner width and the roller diameter. With that data, or with the code of the original chain, we can quote you the Diamond equivalent. Write to us on WhatsApp.
- What lubrication does a roller chain need?
- It depends on the speed and the load. In general, oil or grease specifically for chains is used. Frequent lubrication reduces wear and elongation. Ask us about the right lubricant for your application.
