The application of self-aligning roller bearings in mining excavators

The mining excavators are constantly operating in dusty and heavy-load impact conditions. The original matching bearings are prone to early wear and overheating, resulting in frequent shutdowns for maintenance. By choosing self-aligning roller bearings, which have strong resistance to impact, strong radial load-bearing capacity, and the ability to compensate for shaft alignment deviations, the problem can be solved. After installation, the bearings can withstand the continuous impact loads during excavation operations. The dust-proof and sealing structure prevents the intrusion of mine dust. The continuous operation time of the equipment is significantly increased, the service life of the bearings is extended, the downtime for maintenance is greatly reduced, the operation and maintenance costs of the mine are lowered, and the stable and continuous operation of the mining and excavation operations is guaranteed.
