ceramic spindle bearings

PYC bearing is a specialized manufacturer of ceramic spindle bearings,ceramic spindle bearing.

The ceramic spindle bearings system is one of the most critical and essential component of any high speed spindle design. The spindle provides high rotational speed, transmits torque and power to the cutting tool, and is worthy of reasonable loading and life. The bearing type used in a spindle must be conform with these demands. Otherwise spindle will not operate or perform to its best. Today, a wide variety of high precision bearings is available from a several manufacturers worldwide. In the bearing system of the spindle, the balls roll between the inner and outer steel raceways.

Types of high speed ceramic spindle bearings
The type of bearings available for spindles are as follows:

Angular contact ball bearings: These are the most commonly used bearings today in very high speed spindle designs. Also known as precision ball bearings, they provide the precision, load carrying capacity ( both axial and radial load carrying capacity ) and speed required for metal cutting spindles.

Roller bearings: The roller bearings, also called cylindrical bearings offer higher load carrying capacity and greater stiffness than angular contact ball bearings. They are applicable in spindles with specific rpm requirements and applications.

Tapered roller bearings: These bearings are used, because of their higher load capacity and greater stiffness over ball bearings. But they do not allow the high speeds required by many spindles.

Characteristics of spindle bearings
Axial load supported in one direction only.
Necessary of adjustment against a second bearing.
Compared to deep groove ball bearings, spindle bearings have extended ball complement.
High rigidity and loading capacity.
