Vibration Screen Bearings

Vibration screen bearings are mostly used in mines vibration machine, vibration screen machine, vibration motor. Vibration screen bearings are the most important parts of these equipments. This kind of bearing working in bad environments, air humidity, dusty fields, high running speed, high temperature and huge vibration impact. All these result the working loads get heavier. This kind of bearings have high capacity of taking loads, well impact resistance, high reliability, well lubrication, can also avoid deformed.

Vibration screen bearings are usually symmetrical special spherical roller bearings and cylinder roller bearings for vibration screen;

Generally, dimension tolerance is P6, running tolerance is P5, the tolerance is regular, but they can be divided as English system and metric system;

Because of vibration screen bearings have high heat, it choose big clearance. But the clearance can be calculated. Mainly consider the original clearance, combine tolerance and temperature raising, it can be calculated;

Vibration screen bearings have a high standard for usage, usual bearing steel doesn't work. Cages are made of machining brass and guide by outer ring, in order to fit the situation of eccentrically loads.

Mainly used in mines vibration machine, vibration screen machine, vibration motor;

Clinch bolt machine, rock drill, air chipper and other pneumatic tools;

Electric drill, electric saw, gasoline chainsaw for forestry, wheel machines, polisher grinder tampers machine and other electric machine;

Diesel locomotive, ships, motorbike and other transfer tools;

Tractors, harvester, threshing machines and other farm machinery.

Vibration screen Cylindrical roller bearing, anti - vibration withstand high temperature bearings can be used in vibration screen, vibration grinding mill, vibratory roller and other vibration machine. This kind of bearings not only have double-row spherical roller bearings' capacity of heavy loads but also have cylinder roller bearings' advantage of high limited running speed.

Characteristics:

1. Running loads are 21% higher than usual bearings, it makes the service life increase 91%;

2. Limited speed is 88% higher than usual bearings;

3. The friction torquein the whole range of spped is small, that's 25% smaller than usual bearings;

4. Running noise is low, because the roller body has been chaged by statics;

5. Use whole cages, hace high reliability;

6. Allow hifh capacity to take axial loads;

7. Well heat stability, because of the optimize of cooling (over 800 degree);

8. Introduce overseas advanced technology, use imports steels.

Vibration screen Spherical roller bearings are bearings installed with tambour roller in the middle of the inner ring with two raceways and the outer ring which use raceway as spheres. They can be divided into cylindrical inner hole and conical inner hole.

Vibration screen Spherical roller bearings have two rollers, mainly take radial loads an also take axial loads from any direction in the same time. With high radial loads, especially apply to the work in heavy loads and vibration loads. But it can not take only axial loads. The outer ring raceway is spherical surface which contribute to aligning function, can fix coaxiality errors.

3. The friction torquein the whole range of spped is small, that's 25% smaller than usual bearings;

4. Running noise is low, because the roller body has been chaged by statics;

5. Use whole cages, hace high reliability;

6. Allow hifh capacity to take axial loads;

7. Well heat stability, because of the optimize of cooling (over 800 degree);

Our vibration screen bearings have the following characteristics:
