THE USE OF THE BEARING
Some tips on use
Rolling bearing is a precise part. Therefore it should be used carefully. No matter how high performance the bearing has, it can be obtained by improper use, the followings are the points for attention to use bearings.
(1) Keep clean the bearing and its surrounding areas
It is harmful to the bearing even by tiny dust which can not be seen by human eyes. Therefore it should always keep clean the surrounding environments in order to prevent the bearing from dust corrosion.
(2) Use bearing carefully
Scar and indentation can essily be produced out of strong impact to the bearing in use and become the cause of accidents. Therefore special caution should be given to its use.
(3) Use the appropriate operating tool
Avoid using a hammer or heavy direct tap on a bearing or sleeve, must use appropriate tools such as press or heating.
(4) Be careful to the rust corrosion of the bearings
The sweat in the hands will cause rust in operating the bearings. Therefore your hands should be cleanly washed and dried before operation. You'd better wear gloves in doing the work. 
(5) Handler should familiar with bearing
(6) Establish bearing handling criteri

Installation Instructions

 Bearing mounting
 Precautions for proper mounting of bearing
1) Bearing preparation
Bearing should not be unpacked until before mounting due to spray anti-corrosion oil and pack anti-corrosion paper. In addition, spray anti-corrosion oil on bearing have good lubricate function. For general purpose, just directly using bearing fill-in grease bearings, without cleaning. However, bearing for instrument or high speed rotating must be cleaned with clean filtered oil in order to remove the anti-corrosion oil. At that time, the bearings are easy to corrosion could not storage long term.
2) Inspection of shafts and housings
Cleaning shaft and housing, confirming no scratched or machine burrs, no abrasive and cutting piece in housing. Secondly comppare with drawing, the shaft and housing of dimension, form and machining quality should be inspected.
chart 1 Measure location for shaft diameter                                                                         chart 2  Measure location for housing bore diameter                       

As chart 1 and chart 2 showing, divided several locations to be measure on shaft and housing bore diameters, It should be careful inspected perpendicular between shaft, housing fillet dimension and shoulder.
Before mounting bearing, it should be sprayed mechanical oil on fitting surface after check out the shaft and housing.


Bearing storage
Before leaving the factory, the bearing is sprayed proper rust-inhibiting oil and packed rust-inhibiting paper. The quality of bearing is guaranteed, if the packing is not broken.
For long-term storage, if the humidity less than 65% and the temperature about 20, it should storage on shelf which is higher 30cm than ground.
In addition, storage occasion should avoid sunshine and contact with cold wall.
