Today, smooth ceramic ball bearings have become quite popular and the introduction of using ceramics has greatly benefited the manufacturing process.

Ancient man used round rollers to relocate the heaviest of items. Present day ball bearings most likely evolved through the use of logs. These rollers were placed beneath anything heavy and the item would be dragged along as the logs rolled forward underneath it. There are even images of ancient Egyptians using this type of system to drag the huge stone blocks used in the creation of the great pyramids. Eventually this concept evolved to the point that the rollers were attached to the item being moved and the first vehicle with wheels was born.

As it turned out, the world would have to wait awhile until the concept was further developed. It was not until very late in the eighteenth century when the first bearings were actually designed. Philip Vaughan was an iron-master in Wales and in 1794 he submitted a patent for a carriage axle. That original design was improved upon through the next century and into the early 1900s. The development process was ultimately accelerated by the emergence of bicycles and automobiles.

The most recent technological advances in this field involve the use of ceramics in the ball bearing manufacturing process. Ceramics has revolutionized the industry with its durability and provides additional advantages when used as the base material.

Ceramic ball bearings are particularly useful when used in high speed systems. Ceramics is the preferred material because the high rigidity and low density are able to dampen friction, heat and vibration when it use. Low friction means the whole system runs smoother.

The same properties that reduce friction also give ceramics an electrical insulation component that is quite useful when used in electric motors, various hand tools and fluid machinery. The ability to perform despite less than ideal operating conditions also makes ceramics a popular material to work with.

One of the biggest benefits of ceramic ball bearings is the durability. Ceramics far outlasts other materials and can be effective up to ten times longer than a bearing made out of steel. Durability is the key to keeping machinery running at optimum capacity. Anything that can be done to reduce maintenance costs and down-time for equipment will allow you to realize a huge cost savings in the future.Centuries ago, the concept of ball bearings was conceived and that concept has evolved over many centuries.

Molly, a seven month old kitten, wandered off from the home of her owner Denise Traynor, of Lyttleton Avenue, Charford, last Wednesday.

After Denise made repeated calls to the RSPCA and animal rescue centres, Molly eventually turned up on Friday evening.

But Denise was horrified when she saw that Molly had a huge swelling to one eye.

She was taken to the vet, who believed Molly had a contracted a serious eye infection, so gave Denise pain killers and antibiotics.

Molly then had to be taken back to the vet later that evening to have what remained of her eye removed.

Denise slept downstairs with the cat that night, to make sure she was comfortable, and was woken by her frantic partner on Saturday morning at 5am.

Denise said: “Molly was lying on the sofa and the lump had completely gone, there was now just the hole where her eye had been, but next to her on the sofa was a massive ball bearing.”

The owner said she felt physically sick when she realised what someone had done to her kitten.

“I can’t believe someone could do this to a tiny defenceless animal. It’s sickening. I hope these people see what has happened to Molly and feel some kind of remorse at their totally inhumane behaviour.”

A police spokesman confirmed the incident had been reported to them and asked for anyone who say anything suspicious between Wednesday and Friday, to call them on 0300 333 3000.
