The advantages of vacuum pump bearing bushings are mainly reflected in the following aspects:

Excellent high temperature resistance: In high temperature environments, the thermal expansion and corrosion of the bushing are significantly lower than those of the bearing, thanks to its material properties and structural design. The shaft sleeve can effectively resist deformation and corrosion caused by high temperature, ensuring the stable operation of the vacuum pump under extreme temperature conditions. Strong anti dust pollution ability: The gap size of the shaft sleeve can be precisely controlled through processing technology, reducing the possibility of dust and other impurities entering the interior of the equipment. In contrast, there is more clearance between the ball of the bearing and the cage, making it more susceptible to dust pollution. This characteristic of the shaft sleeve helps to extend the service life of the vacuum pump and reduce maintenance costs.

Self lubrication characteristics reduce maintenance requirements: Shaft sleeve materials usually have self-lubricating function, which can achieve low friction operation without the need for additional lubricants.

. This feature not only simplifies the maintenance process, but also avoids equipment failures caused by insufficient or excessive lubrication, improving the reliability and operational efficiency of the vacuum pump. Outstanding wear resistance and extended service life: The shaft sleeve adopts a face-to-face contact method, which has higher wear resistance compared to the point to point contact of bearings. During long-term operation, the shaft sleeve can effectively reduce wear, extend equipment service life, and reduce replacement frequency and cost. Accurate and stable positioning and support: The shaft sleeve provides precise positioning and stable support for the shaft, ensuring high-precision operation of the shaft inside the vacuum pump. This characteristic is crucial for maintaining the performance of vacuum pumps, helping to reduce vibration and offset, and improving the overall stability of the equipment.

Significant sealing assistance effect: The shaft sleeve and seal are tightly matched, which can significantly enhance the sealing effect and effectively prevent the leakage of the medium inside the vacuum pump.

. This feature is of great significance for ensuring the safety of the working environment and the continuity of production, while also helping to improve the pumping efficiency and vacuum degree of the vacuum pump. Reduce friction coefficient and improve efficiency: The shaft sleeve is usually made of wear-resistant materials with low friction coefficient, which can significantly reduce the friction between the shaft and other components. This feature helps to reduce energy consumption and heat generation, improve the efficiency of vacuum pumps, and reduce operating costs. Strong adaptability to meet diverse needs: The shaft sleeve is not only suitable for harsh environments such as high temperature and high dust, but also can play a stabilizing role under special conditions such as vacuum and strong corrosion. Its wide adaptability makes the shaft sleeve an indispensable and important component in mechanical equipment such as vacuum pumps.
