Diamorph Bearings

Diamorph has developed Diabear™, a ceramic roller for bearing applications. The material is a strong, tough, lightweight ceramic material ideal for applications such as rolling elements for bearings. Diabear™ is especially developed for hybrid bearings, where ceramic rolling elements are combined with steel rings, to serve as lighter and more durable alternatives to conventional all-steel counterparts. Numerous advantages over the all-steel bearings make the hybrid bearings a high-quality solution in a number of fields, said advantages including:

• Higher speeds
• Longer service life
• Lower weight
• Higher reliability at high speeds and loads
• Higher stiffness
• Higher resistance to corrosion
• Electrical insulation
• Non-magnetic
• Reduced need of lubrication 

Diabear™ rollers are manufactured in standard dimensions or in customized designs for your specific application. One core competence for Diamorph is to produce a wide variety of roller sizes with the same high quality of the material independent on component size. The Diabear™ material offers the following advantages:

• Strong
• Homogenous microstructure
• Hard
• Pore free
• Tough
• Light weight
• Wear resistant
• Thermal shock resistant
• Corrosion resistant 

One interesting area for Diabear™ is wind power turbines, where long lasting, high quality bearings are highly attractive due to the high wind power plant service costs.
