Customized rolling bearings
Apart from ISO series bearings, CEROBEAR also manufactures custom-made hybrid spindle roller bearings for your specific application case. These bearings are also available in low quantities.
Following, a selection of possible adaptations and special shapes:
Free choice of the bearing dimensions
Apart from standard DIN sizes, the dimensions of Cerobear rolling bearings can also be individually adapted to our customer's requirements. This means that bearings with different overall dimensions can be manufactured.
Adjustment of the bearing tolerances
CEROBEAR hybrid spindle roller bearings are usually manufactured in the tolerance class SP. However, we are also able to manufacture the bearings with tolerances adapted to specific customer requirements.
Adjustment of bearing play
CEROBEAR hybrid spindle roller bearings are manufactured in the bearing play class C1 specified in DIN 620. In addition it is also possible to manufacture the bearings in bearing play class C2 or individually adjust the radial bearing play to the requirements of the specific application. If the bearing play is non-standard, this is identified with the suffix CX in the bearings match code.
Adjustment of the bearing stiffness
The stiffness of the bearing can be adjusted to the requirements of the respective application by varying the number of rolling elements in bearings of the same type.
Use of special materials
Different and special materials can be used for the various bearing components while taking into account the operating conditions. This permits an optimum adaptation of the bearing to the application.
Adjustment of the bearing seal
CEROBEAR manufactures bearings with various seal solutions as required. For example, it is possible to manufacture sealing washers with an overlap or gap to the counter surface of the bearing ring.
Bearing with oil duct
If the bearings are directly lubricated with oil, suitable oil ducts and grooves can be manufactured in the outer ring as required by the customer. Different positioning of bore holes is also possible.
Various types of anti-rotation devices are available to fix the bearing to the mating parts or associated components.
Bearings with steel rolling elements
If ceramic rolling elements cannot be used, bearings with steel rolling elements can also be supplied, if allowed by the operating conditions.
Integrated sensors and actuators
The behaviour of rolling bearings will be increasingly monitored by sensors and actively influenced by actuators in the future. The pressure and temperature are measured directly in the rolling contact patch by means of thin-film technology. CEROBEAR is actively involved in the development of such systems.
Our technical support service will be pleased to be of assistance in designing a customized CEROBEAR hybrid spindle roller bearing for your application case.
