Tsubaki’s corrosion protected N.E.P. Chain Offers High Performance in Wet and Corrosive Environments.
BS N.E.P. chain is suitable for use in environments exposed to seawater, acid rain and other adverse weather conditions. Environmentally compliant, N.E.P. chain offers the advantage of not containing any chemically hazardous substances such as Hexavalent Chromium, Lead, Cadmium and Mercury, as regulated by RoHS (Restriction of Hazardous Substances).
BS N.E.P. chain is a standard Tsubaki BS chain that has undergone a special surface treatment process. The link plates, bushes and bearing pins of the chain have a special three-stage coating applied in order to provide the maximum protection from the operating or environmental conditions. In addition, the chain rollers have a special coating designed to resist corrosive conditions, and the severe dynamic contact between roller and sprocket; and the spring clips are manufactured from SUS301 stainless steel.
For operations above +60°C a special high temperature lubricant is required.
A standard box length - 5 metres.

Tsubaki PC Chain

Tsubaki’s light weight lube-free PC chain offers corrosion resistance and extended wear life in wet environments.
Tsubaki’s innovative range of PC chain combines the benefits of stainless steel and engineering plastic to create a lube-free hybrid chain for applications where corrosion and a lack of lubrication are a problem. Available in drive, conveyor and attachment variations, the new PC series chains offer resilience to outdoor conditions, detergents and steam; as well as food ingredients such as oils and lactic acid. The solid engineering plastic inner link design promotes easier cleaning and allows lube-free operation, extending chain life in poor lubrication situations.
Tsubaki’s latest PC chain is up to 50% lighter than BS standard roller chain. The solid engineering plastic inner links are specially formulated to provide lube-free operation; producing a longer lasting alternative to all stainless steel versions, where the metal to metal contact in poorly or non-lubricated conditions create premature and unwelcome wear. Cleaning operations are also improved thanks to this inner link design, making the chains suitable for machinery operating in wet environment or food processing as well as clean room applications where lubrication is not possible.
Dimensionally interchangeable with BS and ANSI SS chain, the SUS304 stainless steel pins and pin link plates ensure chain strength similar to full stainless steel products, and allow chain speeds of up to 70 metres/minute to be achieved. Specification of food-grade materials, and the availability as drive, conveyor or attachment variations, ensures the new PC chains can be used in the broadest possible range of applications across food, packaging, pharmaceutical, healthcare and electronics industries.
The reduced weight and effectively maintenance-free operation of the new chains also reduces wear to drive sprockets, further reducing downtime and costs. With the combination of materials used for PC chain another key advantage, as well as reduced weight, is lower noise levels being 5dB lower than BS standard roller chain.
Machine builders and engineers can achieve overall cost benefits when replacing all stainless steel BS chain, sizes RF06B to RS12B. A standard box length - 5 metres.
