Vibrating screen bearings in mine vibrating machinery equipment, vibrating screen machinery, and vibrating motors is crucial. These bearings are exposed to harsh working conditions, including high humidity, dust particles, high speed, high temperature, and strong vibration impact. Despite these challenges, the bearings exhibit strong load-bearing capacity, excellent impact resistance, high reliability, efficient lubrication performance, and the ability to withstand shaft deflection.
1. Characteristics
1. Vibrating screen bearings are typically designed as symmetrical spherical rollers or cylindrical rollers.
2. Generally, the dimensional tolerance is P6, and the running tolerance is P5. Although these tolerances are fixed, there are variations between inch and metric measurements.
3. To account for the significant heat generation, a large clearance is chosen. However, this clearance can be calculated by considering factors such as the original clearance, tolerance fit, and temperature rise.
3. Application Fields
1. Primarily utilized in vibrating equipment for mining, such as vibrating screens and vibrating motors.
2. Used in pneumatic tools like rivet guns, rock drills, and air shovels.
3. Suitable for electric tools including drills, saws, chainsaws, grinders, polishers, road maintenance tampers, and other electric tools.
4. Compatible with diesel locomotives, ships, motorcycles, and other forms of transportation.
5. Ideal for agricultural machinery like tractors, harvesters, threshers, and more.
4. Classification
The KZ23 type cylindrical roller anti-vibration and high temperature resistant bearing is specifically designed for vibrating machinery such as vibrating screens, mills, and rollers. This bearing combines the large load capacity of double row spherical roller bearings with the high limit speed of cylindrical roller bearings.
Features:
① The dynamic and static load-bearing capacity is 21% higher than that of regular bearings, resulting in a 90% increase in service life.
② The limit speed is 88% higher compared to regular bearings.
③ The friction torque throughout the entire speed range is minimal, measuring only 2.
