2 Benefits Imroved erformance Tsubaki P chain offers a cleaner and longer lasting alternative to stainless steel chain, for alications where corrosion and a lack of lubrication are a roblem. Being far lighter than stainless-steel chains an additional benefit is lower noise. Lower maintenance costs Dimensionally Interchangeable with BS and ASI chain sizes, Tsubaki P chain benefits from reduced chain wear and the good news for customers - less maintenance. Lube-Free Long wear life - without lubrication Features Lube Free oeration Longer wear life Light weight Wide range of materials including Food Grade Low oise Environmentally Friendly Wide range of attachments Wide range of alications Available with a wide range of configurations, and with a full comliment of attachments (A-1, K-1, SA-1, SK-1, D-1 and D-3) there is a P chain for virtually any alication. Industry Alications: Food rocessing Packaging Pharmaceutical Healthcare Light electronics Small conveyors...and many more besides 1

3 Light weight Suitable for clean environments Tsubaki ASI & BS standard P chain Engineering Plastic ombination hain (P) uses stainless steel outer link lates and ins for strength, it also emloys resilient engineering lastic inner links to reduce weight and imrove wear life, without lubrication. Tsubaki is the ioneer of this chain secification having first launched the ASI series over ten years ago with it often being referred to as Poly Steel chain by many satisfied customers. Resilient to outdoor conditions, detergents and steam as well as food ingredients such as oils and lactic acid, this roduct can rovide an ideal solution for avoiding corrosion in a wide variety of machinery alications.

7 Solution roviding Innovations in lastic have created the erfect line-u of Tsubaki lastic chains and now solve roblems such as friction, static electricity build-u, chemical corrosion, hygiene roblems and others. Environmentally friendly Environmental rotection is one of the most imortant issues within the Tsubakimoto hain grou. Therefore this new line-u of lastic chains addresses the needs of the 21st century, roviding for energy saving, easy recycling and lower demands on nature s materials. Bacteria and mould in humid areas Short wear life ur solution: MWS hain Unstable conveying due to oor sliding Excessive line ressure Toling bottles Short wear life High running cost Exensive lubricant ur solution: UMW hain Damage by hot water and high temerature Damage by sterilizing Wear from high seed conveying ur solution: KV hain orrosion in acid and alkaline environment ur solution: SY hain eration under UV light ur solution: UVR hain Inclined conveying in dry environment Damage by imact Damage by high temerature ur solution: DIA hain Moist environment Damage by imact orrosion in chemical environment eration under UV light ur solution: DIY hain These are just a few examles of roduct suitability.

10 orrosion Resistance Guide When selecting an aroriate chain for your alication, lease consult the guide below to ensure that your chain is sufficiently resistant to the corrosion induced by substances with which it will be in contact. The results in this guide were observed during tests in an environment of 20º. As actual substance reactivity is subject to a wide variety of factors (ie ambient temerature, exosure time, etc.) This guide is offered no guarantee, but as an aid in selecting the most suitable chain for your oerating conditions. = Highly resistant = Partially resistant x = ot recommended - = ot tested hain sec.
