b.dry Maintenance-free Stainless Steel Chains

Stainless steel redefined: extremely wear-resistant, corrosion-free, and completely dry!

Where re-lubrication is unwanted or impossible, b.dry chains show their full potential: hygienic and completely lubricant-free, they stand unmatched in performance. Their wear life is significantly longer than comparable chains: twice as long in dry conditions, and even four times longer with initial lubrication.

b.dry chains are made from corrosion- and maintenance-free CF stainless steel with an optimized articulated link — the key to b.dry’s precision and success: because "steel on steel" is a thing of the past!

Lubricant-free operation is thanks to our b.dry bushings, made from a special high-performance polymer. This material is undeniably unique in its capabilities:

b.dry products run completely dry while still offering greater wear resistance, corrosion resistance, break strength, and significantly longer service life compared to comparable chains.

Intelligent Chain Bushing

b.dry chains run completely dry because lubrication is not necessary thanks to newly developed high-performance polymer sliding bearings in the articulated link.
The high-performance polymer bushings are FDA-compliant, highly durable, and friction-efficient.

Contact with food or hygienic products is safe and harmless.

Further technical Highlights

Properties of individual parts that are perfectly harmonized with each other reduce chain wear and dramatically increase service life. b.dry chains are extremely reliable, withstand high dynamic loads and are corrosion-resistant.
Stainless steel bushes: thin-walled, seamless and ball-drifted. This gives b.dry chains greater strength and considerably increases their resistance to wear.
CF base chain is made from austenitic stainless steel.
Extremely high resistance to aggressive media.
Temperature range: –100 °C through + 200 °C.
in dry state state PWIS-free

Also available as roller chains with attachments or extended pins and as custom-developed chains. ANSI chains also on request.
