When humidity, washdowns or chemical exposure shorten the life of a standard roller chain, the TSUBAKI NEP series offers a corrosion-resistant alternative. MR Industrial Accessories LLC supplies this chain from Miami to customers throughout the United States and Latin America, and can help you match the right pitch and strand count to your equipment.
Reading an NEP part number is straightforward once you know the pattern. The digits after RS give the ANSI pitch: RS35-NEP-1 is pitch 35, RS40-NEP-1 is pitch 40, and so on. NEP marks the corrosion-resistant version, and the final digit tells you the number of strands—1 for single, 2 for double. Those three elements (pitch, treatment, strands) are enough to identify the chain you need.
These chains suit plants where moisture and cleaning agents are part of daily operation: food and beverage processing, meatpacking, wash bays, surface treatment, and any high-humidity area. They also fit equipment exposed to weather or chemical vapors, where a standard chain would rust and fail early.
Selection depends on pitch, strand count, and the sprocket the chain will run on. Even with corrosion protection, installation matters: check sprocket alignment, set proper tension, and follow the lubrication recommendation for the application. In very aggressive settings, also review sealing and inspection intervals. A chain that is installed and lubricated correctly will last longer, even under harsh conditions.
ANSI roller chains are compared by pitch and strand count, so equivalents exist across manufacturers. But with the TSUBAKI NEP series, pitch alone is not enough—confirm that any replacement carries comparable corrosion protection. If you are unsure, send the full part number and describe the working environment, and we will help you find a suitable option.
To request a quote for a TSUBAKI NEP series roller chain, message us on WhatsApp with the part number or model you use. MR Industrial Accessories LLC replies promptly with the information you need. We can also assist if you are building a new transmission or replacing an existing chain with a more corrosion-resistant version.

Frequently asked questions
- What does NEP indicate in the chain designation?
- NEP identifies the TSUBAKI version for corrosive environments. The number after RS is the ANSI pitch, and the last digit is the number of strands. For example, RS40-NEP-1 is a pitch 40, single-strand chain with anti-corrosion treatment.
- How is it different from a standard roller chain?
- The NEP series is built to resist corrosion in humid conditions, frequent washdowns, or exposure to chemical agents. A standard chain rusts and wears faster in those settings. The NEP keeps the transmission running with less maintenance and a longer service life.
- How do I request a quote for the chain I need?
- Send us a WhatsApp message with the full part number from the chain or equipment, such as RS50-NEP-1. If you do not have it, provide the pitch, the number of strands, and a photo of the sprocket. We will quote you promptly.
