Make a careful installation on bearings.The expected result might be hard to obtained if some mistake is made in installation regardless of the accuracy of bearing.Always pay attention on following points(reference):
1、Always maintain a clean bearing working postion and surroundings.Keep in your mind that even a speck of dust will e a hidden peril.Do your best to minimize the effect of dust on bearings.
2、Always avoid bearing from stong collision or impact to prevent bearings from dent or damage.which will become a hidden peril.Warning:bearing might be cracked or broken in heavy cillision or impact.
3、Always use proper assembly tools and rough assembly is forbidden.
4、Always protect bearings from rusting.It is better to ure tools to handle bearings to prevent bearings from corrosive gas and sweat stain
Installation
A correct installation of bearings will affect accuracy,service life and performance.it is necessary to work out a correct installation procedure and implement following working rules:
1、Parts related to bearings.
2、Inspect dimension and finishing of related parts.
3、Installation.
4、Inspect after installation of bearings. It is prefrable to unpack the bearing immediately before installation.The installation procedures depend upon the bearing structure and fitting condition.It needs an override fitting for rotary shaft inner race.When it is mouted on the outer casing,a general gap is acceptable in fitting with override on the outer race.Normally,it uses press to press it in.
Inspection for a correct installation
A trial running is required to check if it is a smooth rotation.Inspect it for any unsmoothed rotation caused by any foreign matter,scar or dent.
Inspect it for any uneven fotary torque caused by any incorrect installation or bad machining of seat.Inspect it for too big torque caused by too small gap,installation error or sealing friction.
Disassembly
Always use special puller to disassemble the bearing and the claw of puller must clamp the side of inner race securely.
