Ceramic ball angular contact ball bearing is a wide application of industrial ceramic at industrial fields, that is, use hot pressed Si3N4 ceramic ball as roller, and the bearing ring is steel too. Ceramic ball angular contact ball bearing is maintenance free and is especially suitable for high speed application.

1. The ceramic ball contact is resistant to high temperature and has a small thermal expansion coefficient. Under high temperature environment, the bearing roller will not expand due to temperature. The temperature of the ordinary bearing is 160 ° C, and the temperature of the ceramic ball bearing is 220 ° C. which greatly improves the high temperature resistance of the bearing.

2, the ceramic ball angle contact, because of the specialty of the ceramic ball, it has self-lubricating property and small friction coefficient. The ceramic ball bearing has a very high rotational speed, the rotation speed of the ceramic ball is more than 1.5 times that of the common bearing.

3, ceramic ball angular contact life is long, because the ceramic ball has self-lubrication property. Comparing to the general bearing grease may dry, the ceramic ball can operate without adding grease; It also improves the service life of the bearing, which is 2 to 3 times longer than that of the general bearing.

4, ceramic ball bearings have insulation property, the ceramic ball separates the inner ring and outer ring of the bearing and the ceramic ball is not conductive, so it can be used in the conductive occasion with normal operation.

Bearing cage

The high-quality cage used by QIBR bearings ensure that the balls are evenly distributed in the bearing rings and can be rotated properly.

The cage has stamped steel wave type, stamped steel rivet type, nylon or phenolic plastic.

QIBR offers a wide range of advice and options depending on the operating conditions.

Type of lubrication

Lubricating oil is the basic lubricant for ball bearings. Previously most of the lubricating oil was extracted from petroleum. Synthetic oils are now acceptable due to improved performance, such as two lipid synthetic oils, silicones and fluorocarbon synthetic oils. In general, lipid synthetic oils have better low temperature properties, lower volatility, and better temperature characteristics and viscosity compared than petroleum refined oils. Essentially all lubricants contain additives to inhibit chemical changes, prevent metal corrosion, and improve physical properties (antifoam, etc.).

The silicone and fluorocarbon synthetic oils that adopted by QIBR have lower volatility and wider temperature/viscosity characteristics.

Service life and the rated load

The bearing life is the number of bearing rotations before the fatigue occurs on the ring or any rolling element (or the rotation time at a constant speed). However, the same set of bearings will not necessarily have the same life under the same conditions. In this case, the rated life is the number of rotations that 90% of the bearings in this group can reach or exceed before bearing weariness (or the rotation time at a constant speed). The service life of QIBR series bearings are 10%-20% longer than other bearings of the same model, through strict production process, high standard material selection, precision control.
