Slewing bearings (also known as slewing supports) are crucial rotating components in large machinery, widely used in cranes, excavators, construction machinery, wind power equipment, robots, metallurgical equipment, and automated production lines.
Due to their ability to withstand heavy loads and impact loads while maintaining precise rotation, proper daily maintenance not only extends the service life of slewing bearings but also effectively reduces failure rates and improves overall equipment operating efficiency.
This article will comprehensively analyze slewing bearing maintenance methods, lubrication techniques, and usage precautions based on actual working conditions, helping companies to perform equipment maintenance more scientifically.
Why is routine maintenance of slewing bearings crucial?
Slewing bearings are exposed to various factors during long-term operation, including dust, moisture, corrosion, load impact, and poor lubrication. If maintenance is not timely or standardized, it can easily lead to:
Increased operating noise
Slewing jamming or instability
Accelerated raceway wear
Decreased load-bearing capacity
Frequent malfunctions, impacting production
Significantly shortened service life
Establishing a standardized routine maintenance system is an effective means to ensure stable equipment operation and reduce downtime.
Routine Maintenance Methods for Slewing Bearings
Regular inspection and cleaning are fundamental.
Regularly observe the operating status and appearance of the slewing bearing, focusing on:
Abnormal wear or cracks
Lubricant leakage
Smooth rotation and any unusual noises
Loose mounting bolts
During daily cleaning, use a clean brush or compressed air to remove dust and impurities, preventing foreign objects from entering the raceway and affecting rotational accuracy.
Lubrication Maintenance
1. Rolling Element Raceway Lubrication
Lubricant Selection:
High-quality, heavy-duty, extreme-pressure lithium-based grease is typically required.
The manufacturer’s recommended model and specifications should be strictly followed. Special operating environments (such as high temperature, high humidity, or extreme cold) may require specialized greases.
