Vibrating Screen Bearings

Vibrating screen bearings are mostly used in mine vibration machinery equipment, vibrating screen machinery, and vibrating motors, and are one of the most critical components of this type of equipment. The working conditions of the bearing are very harsh, not only the environmental humidity is high, the dust particles are large, the speed is high, the temperature is high, but also there is strong vibration and shock, which causes the work load to be very large. The bearing has strong bearing capacity, good impact resistance, high reliability, good lubrication performance, and can overcome the deflection and deformation of the shaft.

1. Vibrating screen bearings are generally symmetrical spherical rollers and cylindrical rollers;

2. Generally speaking, the dimensional tolerance is P6 and the running tolerance is P5. The tolerances are indeed fixed, but there are English and metric systems;

3. Due to the large heat generation, a large clearance is selected. But this clearance can be calculated, mainly considering the original clearance, tolerance fit and temperature rise can be calculated;

4. The application requirements of vibrating screen bearings are very high, and ordinary bearing steel materials are not acceptable. The cage is machined brass and is guided by the outer ring to be suitable for eccentric loads.

Application of Vibrating screen bearings

1. Mainly used for mine vibration machinery equipment, vibrating screen machinery, vibrating motor;

2. Pneumatic tools such as rivet machines, rock drills, wind shovel, etc.;

3. Electric tools such as electric drills, electric saws, chain saws for forestry, grinders, polishing machines, grinders, road maintenance tamping machines, etc.;

4. Diesel locomotives, ships, motorcycles and other transportation vehicles;

5. Agricultural machinery such as tractors, harvesters, and threshers;

Cylindrical Roller Bearings

KZ23 type cylindrical roller anti-vibration and high-temperature bearings can be used for vibrating machines such as vibrating screens, vibrating mills, and vibrating rollers. This bearing not only has the advantages of large carrying capacity of double-row spherical roller bearings, but also high limit speed of cylindrical roller bearings.

Features:

①The carrying capacity of dynamic and static load is 21% higher than that of ordinary bearings, and the service life is increased by 90%;

②The limit speed is 88% higher than that of ordinary bearings;

③The friction torque in the entire speed range is very small, 25% smaller than that of ordinary bearings;

④The running noise is low, because the rolling elements are statically optimized;

⑤Using integral cage, high reliability;

⑥ Allowable axial load carrying capacity is high;

⑦Good thermal stability, because the heat dissipation is optimized. (Within 800 degrees)

⑧ Introduce foreign advanced technology and drawings, and adopt imported steel.

Spherical roller bearing

Spherical roller bearings are bearings with drum-shaped rollers assembled between the inner ring with two raceways and the outer ring with spherical raceways. Divided into: cylindrical inner hole, conical inner hole.

Spherical roller bearings have two rows of rollers, which mainly bear the load of one diameter, and can also bear the axial load in any direction. With high radial load capacity, it is especially suitable for working under heavy load or vibration load, but it cannot bear pure axial load. The outer ring raceway of this type of bearing is spherical, so its alignment performance is good, and it can compensate the concentricity error.
