NEP CHAINSUPERIOR CORROSION RESISTANCE
TSUBAKI
Patent Pending
NEP Chain is a tough coated chain with two different optimized coatings for its different parts. (See below.) These special coatings have high corrosion resistance and protect the chain from corrosive environments.
NEP Surface Coating Structure
No rust appeared on the NEP Chain even after 700hrs in a salt spray test. (JIS-Z-2371)
Superior Corrosion Resistance

Tsubaki is eliminating all surface coated chains that contain designated hazardous chemicals* and working towards reducing our environmental load.* Hexavalent chromium, cadmium, lead, etc.
In order to reduce our environmental
load, Tsubaki has developed a
unique eco-friendly surface coating,
featured on our new NEP Chain.
NEP Chain (New Environmental
Plating Chain) has superior corrosion
resistance than our WP or DP Chains,
reducing its load on the environment.

The individual parts of NEP Chains are surface treated - and unlike chains treated after assembly, even the inner parts of NEP Chains are treated.

Chain strength (part hardness) is unaffected thanks to low treatment temperatures.Thus, NEP Chains have the same tensile strength and allowable load as our standard Roller Chains.

■BS/DIN Drive Series is available. Please contact TSUBAKI representative.
■Selection/Handling:
-10˚C − 150˚C(Use a high temperature lubricant when using above 60˚C. Contact a Tsubaki representative when using in temperatures beyond the ranges given.)
Refer to the Tsubaki Drive Chains catalog for information on selection and handling.Catalog No.120
Electrical corrosion may occur when steel chains are used with stainless steel sprockets, promoting premature wear. Avoid mutual contact as much as possible. In-house tests have shown that the middle links of multi-strand chains have slightly less corrosion resistance than with single-strand chains.
