Advanced Engineering Ceramic Project Extends Life of Balls and Bearings

Tests are currently underway on the results of an advanced ceramic project to develop precision balls and bearings for production equipment used by automotive manufacturers.

The application project, which is being undertaken by Jai Engineering, Warwickshire, promises to reduce production line downtime caused by ball bearing failure.

Advanced precision ceramic balls and bearings are replacing bearings made from standard materials, such as tungsten carbide, hardened steel or composites in a wide range of industries.

Their properties are particularly suited to harsh industrial applications such as automotive, chemical pumps, laser-induction welding, and the latest condensing gas boiler technology.

Ceramic materials offers a combination of properties not found in any other material such as: electrical insulation, low density, light weight, high compressive strength and fatigue resistance, superior thermal shock, exceptional resistance to wear, low coefficient of friction, outstanding chemical resistance to acidic or alkaline and excellent corrosion resistance.

All balls and bearings are made either from gas pressured sintered silicon nitride or Yttria-stabilized zirconia.

These bearings can be used up to 800ºC without any lubricants up to 15,000rpm depending on type and size of bearing.

With a background of over 26 years working in research, development and manufacturing, Jai Engineering assists clients with design issues, material selection, cost effective manufacturing and the supply of precision ceramic components and small assemblies
