Characteristics of ceramic self aligning ball bearing

Release time: October 21, 2019 21:20:57 Views: 1202

?? In the development and application of engineering products such as ceramics, ceramics Self aligning ball bearings are widely used in ceramic engineering, The self-aligning ball ceramic bearings, rings and rolling elements are made of zirconia (ZrO2) or silicon nitride Ceramic material, PTFE is used as the standard configuration for retainer. Glass fiber reinforced nylon 66 (grpa66-25), special engineering plastics (PEEK), and stainless steel (AISI) can also be used SUS304) etc., with oil-free self-lubricating, high-speed operation, corrosion resistance, high-temperature resistance, high load, wear resistance, insulation, electrical insulation and other characteristics, can be used in extremely harsh environment and special working conditions. In many countries, the high-speed precision bearings are more widely used in hybrid ceramic self-aligning ball bearings, that is, the hot pressed ceramic self-aligning ball bearings for rolling elements, and the bearing rings are still steel rings. What are the characteristics of ceramic self-aligning ball bearings? Shanghai Yu micro bearing

Feature 1: high temperature resistance. The thermal expansion coefficient of ceramic self-aligning ball bearing is small. In the case of high temperature, the bearing will not expand due to temperature, which greatly improves the service temperature of the bearing. The temperature of ceramic self-aligning ball bearing is as high as 220 ℃.

Feature 2: long life. The ceramic self-aligning ball bearing can be used without adding any grease, which means that the bearing can continue to operate even if the grease is dry. In this way, the bearing damage caused by grease drying out in the ordinary bearing is avoided.

It has three functions: insulation. The bearing made of ceramic self-aligning ball bearing can insulate the inner ring and outer ring of the bearing. Because the ceramic self-aligning ball bearing itself is an insulator, which is used in the bearing to achieve the insulation effect, it can be used in the case of conducting electricity. Rolling bearings are mainly composed of rings, rolling elements, retainers, grease, seals and so on. After using ceramic materials, rolling bearing is also called ceramic self-aligning ball bearing.

Nowadays, ceramic self-aligning ball bearing has been widely used in various fields. From the effect of use, the most prominent is to improve the life and speed of the bearing. In order to develop high-speed and high-precision machine tools, it can provide the most basic parts.
