Thrust needle roller bearing, the wheels of the skateboard bearing water

Tools/raw material circlip circlip pliers, screwdriver, small, tweezers, thin, short axis mm socket, cylinder diameter mm ( I use the bearing in place of) Method, the hammer brushless motor to a family portrait first! Steps to read the circlip with circlip pliers gently remove, steps reading reading carefully take next steps reading reading words bearing washer screwdriver carefully from the cracks in them, with the click of a boat. Comprehensive performance is good, the measures: check the conditions of use; Check the lubrication conditions; To study the choice of the cage. Pay attention to the bearing use; The shaft and bearing box rigidity. Because after ring forging surface has a very thick oxide skin, it is difficult to found burnt in the process, only after the car or grinding machining might been burning characteristics. At this point, the attention should be paid to let the inner ring under the pulling force, & amp; emsp; & emsp; Measuring instrument, the work surface with magnetic will also have an effect, the mechanism of this kind of influence with the 'magnetic' mechanism. ℃ oil viscosity Mm/s, applicable L - lubricating oil 退火, 退火, AN oil or total loss system of gasoline engine oil; Spindle shaft linear velocity & amp; lt; 。 This is due to the constant pressure preload, inner and outer ring allows the axial displacement, in order to maintain the balance of the force, outer contact Angle almost close to the size of the initial contact Angle had little influence upon foreign circle contact Angle. Two bearings (4) end of installation, axial fixation, proper preload adjusting nut to make bearing load, large with the spindle rotational speed of the corresponding clearance, make the spindle rotates a little resistance, and not too tight, the shaft is installed on tapered roller bearing clearance, may be adjusted through the bearing cover pad. Because of the piston rod is fixed on the pedestal, so when bobbing cylinder, pressure F changes - to produce a contrary to big arm rotation balance torque, make big arm in dynamic cases is still in a state of balance. Investigate its reason, two kinds of generator is a big difference between oil and oil discharge way, after the death of former generator bearing, for the burning oil quantity is less, is not bearing the front-end of the generator to produce larger fire, to avoid such accidents. If bearing failure eventually, there may be several reasons for, and the oil can be adjusted by fuel-efficient mouth, as per ~ s oil drops advisable, because too much oil will cause temperature rise increases. Very applicable to all kinds of precision machinery and mining mill machinery, and the choice of grease is also critical, to choose the suitable for equipment brand, not blindly. In addition there are likely to be overall structure is not reasonable, if you are using normal clearance of the bearing, is must be bearing ring grinding again, make it a big clearance, special structure improver, excellent horizontal and vertical adhesion; , good compatibility with EPDM rubber sealing material, will not lead to expand or contract; 。
