Product Details

Construction machinery bearings have the following characteristics and scope of application:

High strength and wear resistance: Construction machinery bearings usually need to withstand high speed and high load, and work in harsh environments, so they need to have high strength and wear resistance.

High temperature resistance: Construction machinery bearings usually work in high temperature environments, so they need to have good high temperature resistance to ensure that bearings can still operate normally at high temperatures.

High rotation accuracy: Construction machinery bearings require high rotation accuracy, which can stably support and rotate rotating parts and reduce vibration and noise.

Good sealing and lubricity: construction machinery bearings need to have good sealing performance, which can effectively prevent the intrusion of foreign bodies such as dust and moisture, and need to have good lubrication performance to reduce friction and wear.
