CEROBEAR hybrid spindle roller bearings open up a significant improvement in the design of spindle systems. They present the optimal solution for the floating bearing side of a spindle shaft. Therefore they are an ideal supplement to spindle ball bearings which require a large amount of engineering efforts if used on the floating side.

Their numerous advantages over conventional spindle bearings make CEROBEAR hybrid spindle roller bearings an economic and high-quality solution in a number of fields of use.

The bearings are produced according to highest precisions. They consist of rings manufactured from high-grade rolling bearing steel and rolling elements made from silicon nitride. Various high-performance plastics such as PEEK or PI are used for the cages.

CEROBEAR hybrid spindle roller bearings are characterised by the following properties:

■ high speeds ■ high reliability ■ high precision ■ high stiffness ■ low friction ■ simple design ■ long service life ■ low operating costs

CEROBEAR hybrid rolling bearings open up whole new fields of different applications for rolling bearings. Their numerous advantages over conventional rolling bearings make them an economical and high-quality solution in a number of fields of use.

CEROBEAR Ceramic bearings

CEROBEAR ceramic bearings make it possible to apply rolling bearings in a variety of circumstances. Cerobear ceramic bearings offer new opportunities of application, especially in extreme technical domains, which have been inaccessible up till now.

The inner and outer rings of the bearings are made of high-performance ceramics such as silicon nitride or zirconium oxide. The rolling elements are also made of silicon nitride. For the production of cages and gaskets a variety of materials, such as PEEK or PI, are available.

CEROBEAR ceramic bearings set themselves apart through the following characteristics:

■ High corrosion resistance ■ Qualify for extreme temperatures ■ Qualify for dry running conditions ■ Low weight ■ Absolutely amagnetic ■ Qualify for media- and starved lubrication ■ High stiffness ■ High reliability ■ Low abrasion ■ Low operating costs
