Installation method:
1. Bearing inner ring and shaft tight fit, outer ring and bearing hole is a loose fit, available press the bearing pressure equipment in the shaft first, then the shaft together with the bearing load bearing hole, when pressed on the bearing inner ring end face, cushion the assembling casing made of a soft metal material (copper or mild steel), bearing outer ring and bearing hole tight fit, inner ring and the shaft is a loose fit, the bearing can be pressed into the bearing hole first, then assembling casing diameter should be slightly less than the diameter of a hole. If the bearing ring and shaft and hole is a tight fit, install an indoor ring and outer ring to pressure into the shaft and hole, at the same timeThe construction of the assembly sleeve shall be able to fasten the end faces of the inner and outer rings of the bearing at the same time.
2. By heating bearing or bearing, using thermal expansion will fit into a loose fit installation method. The installation method is a kind of common and energy saving. This method is suitable for interference quantity larger the installation of the bearings, the bearing before hot charging type or separable bearing ring into the fuel tank even heat 80-100 ℃, and then loaded on the shaft, as soon as possible out of the oil to prevent inner ring after cooling end face and the shoulder joint is not tight, to axial bearing cooling can then tighten. Bearing outer ring and light metal bearing seat tight fit, by heating the hot charging method of the bearing, can avoid the mating surface scratch. Heating tank with bearing and should be at a certain distance from the bottom of a mesh, or hanging hooks in the bearings, bearing on the bottom, in case of heavy impurities into the bearing or uneven heating, fuel tank must have a thermometer, strictly control the oil temperature shall not exceed 100 ℃, in order to prevent the tempering effect, reduce the hardness of the ring.
Usage
1. Electric Motors
Quiet operation realized by proper clearance, recommend the fitting practice. Lower noise lubricants.
Suitable for all speed ranges applications requiring low noise.
2. Automotive Alternators
Longer life in vibrations and high-temperature environments
3. Automotive Starters
High reliability in periodic use of vibrations and high-temperature environments.
4. Compressors
Long-life pump rotors which compress air in low temperature and low viscosity lubrication environments.
5. Blowers
Quiet and stable operation on fan motors at high speed, in environments with vibration and high temperatures
6. Transmissions
Compact design for lightweight to achieve high performance
Advantage
1. It is the combination of 2 machined and polished grooved raceways(inner&outer rings), guiding a number of appropriate balls, separated by a cage
2. This type bearings mainly take the radial load as well as moderate axial load
3. The Vibrating grades are divided into Z1V1, Z2V2, Z3V3.
4. Simple design and suitable for high speeds
5. Large size range and less coefficient of friction
6. Less noise
7. Robust in Operation and normally require little maintenance
1. High swiveling accuracy
2. Low noise
3. Low weight
4. Can be customized according to your needs
5. Can provide small & miniature standard and non-standard ball bearings
