The precision bearing is mainly used in the light load and high speed rotating situation, which requires the bearings with high precision, high speed, low temperature rise and low vibration andlong service life. What should we pay attention to when installing precision bearings? The service life of high speed precision bearings is closely related to installation. The following matters should be noted during installation: 1. Bearing installation should be carried out in a dust-free, clean room.The ring for the bearing should be ground; in the condition of maintaining the inner and outer ring same height, the parallelism of the ring should be controlled below 1um; 2. The bearing should be cleaned before installation. When cleaning, the slope of inner ring should be upwards, and it should be rotated flexibility with no sense of stagnation. After drying, we should put into the delineated amount of grease, such as oil mist lubrication should be put into a small amount of oil mist oil; 3. Bearing installation should use special tools. The force should be average. Beating is strictly prohibited. 4. Bearing storage should be under clean ventilation, no erosive gas, and relative humidity not more than 65. Long-term storage should be rust-proof. View Details

ZYS clutch bearing  installed between the ZYS clutch bearing and the gearbox, separate loose sleevesealed angular contact ball bearings on the transmission of the first axis of the tubular extension of the bearing caps, by the return spring to release bearing shoulder always against the release fork, and retreat to the final position maintain the separation lever ends (separation means) about 3 ~ 4mm gap. The ZYS clutch bearing pressure plate, release lever and the engine crankshaft synchronous operation, and the separation ZYS clutch bearing fork can move axially along the output shaft, with the release fork to direct dial release lever is clearly not enough, by separating the bearing can release lever while rotating an edge ZYS clutch bearing output shaft axial movement, thus ensuring the smooth Super precision ball bearings to engage, separation soft, reduce wear and extend ZYS clutch bearing life and the entire drivetrain.

The outer ring raceway take special processing methods to prevent the emergence of creaks , the choice of the bearings if necessary or appropriate to reduce the bearing radial clearance , excellent performance grease and improve the rigidity of the bearing mating parts .( 1 ) improper installation,  bearings for use is bearings for printing machine very important. I hope we can use the correct installation method in future use.( 2 ) the installation , according to their type and size selected mechanical , hydraulic , or other methods of heating . Force the installation of bearing imposed by the rolling elements must not be passed from one to the other bearing ring bearing ring , or it may be caused by damage to the raceway . But in any case , are not directly tap the bearing ring , cage , rolling or seals View Details

So, why would the bearing vibration it? Today, it is for me to explain something simple for everyone, please read carefully!When changes in the number of rolling  loads, will produce excitation when a radial load on a load of imported bearings, its load bearing rolling element number will be some changes in the operation, which caused the load shift direction . The resulting vibration is inevitable, however, now  Wind turbine bearing seems to have a bearing vibration and noise are reduced, which is why? Nsk bearings due to the current use of the design to  reduce the pre-load, rolling   load at all, thereby reducing vibration, but also reduces the noise. Although the use of the pre-loaded, but can not completely relieve the vibration and noise problems. So, how to further reduce the noise it?1, to prevent resonance excitation components and between the components of the vibration excitation.2, change the stiffness, and to achieve the purpose of changing the critical frequency.3, remove the critical excitation vibration.                 View Details

The role of the stuffing box is mainly to seal the gap between the pump casing and the pump shaft, high speed bearing so that the pump flow not flow to the outside to the pump without the air to enter. Always maintain the vacuum pipeline pump, when the pump shaft and packing friction heat generated is depends on water seal on the curb water to fill the cooling seal circle. Maintain the normal operation of pipeline pump. So in the pump running circuit inspection process of the stuffing box is particularly attention, radial clearance in the run for about 600 hours to replace the filler. View Details
