Before the machine tool spindle bearing has axial, if after the bearing outer ring and shell holes with no clearance, compensation is not caused by temperature change spindle scalability;
If the outer ring and shell holes cooperate with clearance, will cause the spindle runout, affect the machining precision lathe.
After the repair will not produce in the process of using metal fatigue wear, on the premise of normal equipment maintenance, the service life of repaired even higher than the service life of the new parts.
Rolling bearing, by contrast, is greater than sliding bearing radial size and vibration reduction ability is poorer, machinery and equipment under a state of high speed rolling bearing is less than the life of the sliding bearing, noise is high among them is the main purpose of centripetal bearing under radial force, its composition includes parts, namely, inner and outer ring, rolling body and rolling body cage.
Due to pump failure is more, often need to artificial and manually adding grease, fatliquoring quantity statistics is not accurate, the outlet pressure of the pump should be above the MPa, the pressure is insufficient, pipe distributor will not action.
Contact Angle is optimized, can provide specific preloading and under specific wheel load conditions for the new HBU design unit, orbital forming after assembly can be installed on the vehicle when the axial preloading - as needed
Has nothing to do with the final vehicle assembly condition.
Dust cover shields is an annular cover, usually composed of sheet metal stamping, fixed on the bearing ring or washer, and extends toward another ring or washer and obscure bearing internal space, but not contact with another ring or washer.
For use on both ends of large motor bearing seat, can be placed between the bearing and metal base insulation spacer, for rolling mill bearing for wear and tear, tell everyone about roller press bearing wearing repair steps of related knowledge.
See appearance: grease regardless of what kind of pigments present appearance, fat body should have dense paste body, if you open the packing, see surface oil, grease, surface colour depth or skin sclerosis or consistency decreased significantly, or mixed with water and emulsion white fat surface, or grease on the surface of seal cause qualitative change, the fat are unavailable.
Printing professionals know the height of the relief for, but long stored in humidity, temperature less than % about ℃ under the condition that stored in the cm above the ground shelf is advisable.

Used in high speed, high rotating accuracy of rotation mechanism, such as precision machine tool spindle bearings, precision instruments and meters of the main bearing, etc.
When in pneumatic sweep, shaft sleeve, pitting problems fitting surface is point contact repair process, is not a surface contact, leaving long-term safe operation of the equipment, lead to the main shaft of cone and the handle of the cone can't cooperate, mechanical spindle maintenance: reduce the working temperature of bearing, frequently used way is to lubricating oil.

Small said the hole tolerance, capital letter said shaft tolerance)
