6804 High Temperature Resistance Hybrid Ceramic Ball Bearing for Chemical Equipment

Hybrid Ceramic Bearing Detail:

The hybrid ceramic ball bearings have stainless steel rings and ceramic balls. The rings are made from AISI440C, 304 or 316 stainless steel. The ceramic balls are made from ZrO2, Si3N4 or Sic. We can also offer our hybrid ceramic bearings with PEEK or 316 stainless steel cages.

The hybrid ceramic bearing balls has the advantage as below:

1. High speed. The ceramic ball has the properties of oil-free and self-lubricating, and the friction coefficient of the ceramic ball is small, so the ceramic ball has a high speed. According to statistics, the bearing using ceramic balls is 1.5 times the speed of the general bearing.

2. Insulation. Bearings with ceramic balls can insulate the inner and outer rings of the bearing. Because ceramic balls are insulators, using ceramic balls between the inner and outer rings of the bearing can achieve the insulation effect. This enables the bearing to be used in a conductive environment. This is also the biggest advantage of hybrid ceramic bearings.

3. High temperature resistance. The coefficient of thermal expansion of the ceramic ball is small. In a high temperature environment, the bearing ball will not expand due to temperature, which greatly increases the operating temperature of the entire bearing. The temperature of ordinary bearings is about 160 degrees, and the temperature of ceramic balls can reach more than 220 degrees.

4. Long life. The ceramic ball can be added without any grease, that is to say, even if the grease dries out, the bearing can still operate, so as to avoid the occurrence of premature bearing damage caused by the grease dries out in ordinary bearings. According to foreign media tests and feedback from some customers, the service life of bearings after using ceramic balls is 2-3 times that of ordinary bearings.

In 2010s, WI-TECH embarks on the production and supply of ceramic bearings, plastic bearings and hybrid ceramic bearings, and since then we have been a leading manufacturer and supplier of ceramic bearing in China that supports the growth of global industry. At our production plant, which is integrated with advanced technology, we operate the production line for the ceramic bearings and automate everything from processing to quality control.

In addition, the tolerances for bearing finishes are more stringent than the standards of China industrial standards, and our bearings can be fully responsive to demanding conditions such as high-speed rotation. Taking advantage of a specialized manufacturer, Witech ceramic bearings can withstand the severe environment such as heat resistance, corrosion, wearing and magnetic in recent years. In addition, we are highly acclaimed for the production of various types such as stainless steel series and hybrid series.

In contrast with plain bearings, ceramic bearings are easy to install and withstand more severe conditions. We are confident that we will be able to contribute to the industry in a variety of fields. We will continue to create new value for the changing future and to be able to satisfy the user’s needs 100%.
