oilless bearings CB85-2220

The benefits of oil-free bearings mainly include wide application, no need for oil supply device, environmental protection, reduced requirements for wear parts, and high and low temperature resistance. ‌

The five major advantages of oil-free bearings can be summarized as follows: ‌Applicable occasions‌: No oil lubrication or less oil lubrication, suitable for places where refueling is impossible or difficult, no maintenance or less maintenance during use, avoiding the risk caused by insufficient oil supply. ‌No need for oil supply device‌: No special oil supply device is required, saving a lot of installation and operation costs. Oil-free simplifies design and structure, reduces costs, and saves design time. ‌Environmental protection‌: No waste oil recovery and treatment is required, which is beneficial to environmental protection.

‌Reduced requirements for wear parts‌: The hardness requirements for grinding shafts are low, and shafts that have not been tempered can be used, thereby reducing the difficulty of processing related parts.

‌High and low temperature resistance‌: High and low temperature resistance, the applicable temperature range of some products is from -200℃ to 600℃.

In addition, oil-free bearings have other advantages, such as:

‌Good wear resistance‌, low friction coefficient, and long service life.

‌Can distribute stress on a wider contact surface‌, thereby improving the bearing capacity of the bearing.

‌The static and dynamic friction coefficients are similar, which can eliminate creeping at low speeds, thereby ensuring the working accuracy of the machine.

‌Can reduce vibration, reduce noise, prevent pollution, and improve working conditions.

‌A transfer film can be formed during operation to protect the grinding shaft without biting the shaft.

‌Thin-wall structure and light weight‌ can reduce the size of the machine. 

‌The back of the steel can be electroplated with a variety of metals‌, can be used in corrosive media, and is widely used in the sliding parts of various machines. 

These advantages make oil-free bearings unique in many special environments, especially in places with strict environmental requirements and under harsh conditions such as high temperature, high speed, and high load, oil-free bearings can still maintain stable performance‌
