1, selection and control of shaft and housing tolerances: TIMKEN bearings pressure into rotational flexibility should be no block. If there are clearly not flexible rotation, then axis dimensions are too big, the tolerance to cut. If the bearing onto the shaft by hand after turning there is a clear "rustle" sense, the tolerances of the shaft may be too large or the roundness of the shaft well. So when you control the shaft and housing tolerances you want to control the roundness, many domestic manufacturers currently control only tolerance, not to control the roundness.
2, bearing Assembly methods: because the bearings are high-precision products, such as improper Assembly is easy to cause injury to the TIMKEN bearing Raceway, cause damage to the bearing. Bearing Assembly should have dedicated mold, cannot be beat at will, force in pressing axis only small circles, pressing circle only large ring bearing. Assembly call for pneumatic or hydraulic, at the time of pressing die outside to level up or down status, such as tilt can cause mechanical damage of bearing Raceway and the bearing rings.
3, assembling foreign object prevention: TIMKEN bearing when mounted to the rotor dynamic balance easily produced when iron filings into the bearing internal dynamic balance, so it's best to load bearing dynamic balancing before. Some manufacturers for ease of Assembly, Assembly in the bearing room painted with some oil or grease lubrication effects, but in many cases the operator is difficult to control, if oil or grease in the bearing Interior accumulates more easily along the axis of rotation of the bearing into the bearing. Bearing room it is best not to paint oil or grease, such as non-coating is not available to control shall not be bearing Interior accumulates.
4 Prevention of rust, paint: paint and rust is characterized by multiple sealed-type motor, motor Assembly, sounds very good, but after some time within the warehouse, the electrical noise change very large, with serious rust removed TIMKEN bearings. Many manufacturers are considered to be before bearing problems, through our advocacy, motor factory is now aware of the main insulation paint problems. Varnishes used for this issue mainly because of volatile acids under certain temperature, humidity of the formation of corrosive substances, corrosion and cause damage to the bearing TIMKEN bearing Raceway. The problem can only be good choice of insulating varnish, and assembled in the ventilation after drying after a period of time.
