Always dry: maintenance-free stainless steel chains from iwis

The new b.dry precision chains are useful wherever relubrication is undesirable or not possible. They are hygienic and run completely dry: thanks to the high-performance plastic friction bearings in their links, they need no lubrication of any kind, which also eliminates the need for relubrication.

Made from a high-performance polymer, the sleeves are heavy-duty, low-friction and FDA-compliant. Contact with foodstuffs or hygiene products is safe. The stainless-steel bushes are thin-walled, seamless and ball-drifted. The CF base chain is made from austenitic stainless steel, making it highly resistant to aggressive media. The wear life of the b.dry chains is significantly longer than that of comparable chains: in test runs at iwis, it proved two times better in dry conditions and as much as four times better with initial lubrication.

In a dry state, the chains are free from paint wetting impairment substances (PWIS), which is important, for example, in painting lines in automobile manufacture. b.dry chains are made in length tolerances compliant with ISO 606. They can be used in a temperature range from -100 to +200degC. They are also available as roller chains with attachments or extended pins. Custom-developed chains and ANSI chains are also available on request.
