Ball Bearings in Chemically Corrosive Environments

Although the movie processing trade is in its inevitable decline with the appearance of digital pictures, the trade created some applied sciences which might be just too helpful to permit to fade. Premier amongst these is the ball bearing for chemical environments. A singular mixture of supplies permits these bearings to function fully non-lubricated in low to medium speeds and lightweight to medium masses in all kinds of harsh chemical environments usually deadly to conventional bearings. New supplies beforehand by no means thought of for anti-friction bearings at the moment are not solely commonplace but additionally discovering new and distinctive functions.

The first bearing materials utilized in movie processing options was Acetel copolymer, (POM) which due to its hardness and self-lubricating properties made it wonderful within the acidic movie processing chemical substances. Couple this materials with chemically inert glass balls, and a great bearing to function submerged in liquid transporting movie at excessive speeds by way of the answer baths was created.

This ball bearing mixture of Acetel rings and cage with glass balls can also be very helpful for a lot of functions moreover movie processing. In lots of industrial processes utilizing corrosive chemical substances these bearings are excellent. Additionally meals processing functions in such mixers and stirring equipment, beverage bottling equipment, and different functions the place rotating gadgets involved with corrosive environments the place sealed and lubricated bearings aren’t sensible. For example, meals conveying functions that should be frequently steam cleaned for sanitation. One other wonderful utility for these non-metallic ball bearings is for MRI, CT Scan, X-ray and microwave machines the place no metals could also be used.

316 Chrome steel bearings are one other outgrowth of the movie processing trade that has discovered their means into different corrosive atmosphere functions. Non-lubricated stainless-steel ball bearings are perfect for marine, salt spray environments and are used on ship hatches, doorways, deck equipment, industrial fishing tools, submersible tools and plenty of different locations round ships. These are additionally excellent for chemical processing services, chemical loading tools and conveyors, and different locations the place a closely loaded non-lubricated bearing is required to keep up a correspondence with chemical substances or supplies that should be stored clear and lube free.

Plastic bearings with glass, or stainless-steel balls even have one other function that makes them very distinctive and completely different their extraordinarily low weight. In a compact utility corresponding to a surveillance digital camera, this low weight means very low inertia, in order that very low energy motors are wanted to slew the cameras about. Extremely low beginning and rotating friction and a no lubrication implies that these can be utilized in functions needing a large temperature vary additionally.

Each time uncommon chemical environments are encountered, conventional greased and sealed ball bearings create the potential for a fast failure resulting from corrosion. Additionally they run the chance of introducing contaminants into the world when the grease, or the oil contained throughout the grease is launched into the neighborhood of the bearing. By substituting plastic or stainless-steel bearings into the appliance, there isn’t a necessity to lubricate the bearing, so no contaminants are current and if the fabric is correctly chosen, no corrosion happens, significantly decreasing upkeep and unscheduled system failures.
