A, correct installation precision SKF bearing
For installation precision SKF bearing products it, install a to note that some up things, if not installed well, can make the SKF bearing life not long. So if you want to install a good SKF bearing, so should understand the method of installation SKF bearing, so that we can guarantee SKF bearing in the installation process damaged. The following me introduce SKF bearing installation precision calibration method integrated:
1, measuring axis and the size of the hole SKF housings, to determine with precision bearing SKF, cooperate requirement as follows,

(1) inner circle take over surplus with shaft, a surplus quantity of 0 ~ + 4 μ m (in light load, high precision for 0);

(2) the bearing outer ring and SKF hole take clearance fit, clearance is 0 ~ + 6 μ m (but in the free SKF bearings use Angle contact ball bearing, still can increase clearance);

(3) axis and a hole surface roundness error in 2 μ m

(4) used every lap SKF bearing surface parallel degree in 2 μ m

(5) shaft shoulder end in foreign end of the 2 μ m jump

(6) the bearing hole to block SKF shoulder axis beat μ m in April

(7) the front cover the face in the main shaft axis beat μ m in 4,

Second, rust method
The surface of the thing be rust pretreatment methods:

1) surface cleaning: cleaning must depend on the nature of the surface is antirust things at that time and conditions, select the appropriate methods. General commonly used a solvent method, chemical cleaning dealing with cleaning method and mechanical cleaning method.

2) surface dry clean available dry after filtering compressed air blow dry, or use 120 ~ 170 ℃ dryer drying, also can use clean dry gauze.
Apply the method of temporary

1) soaking method: a few small SKF bearing by soaking in the rust of oil, make its surface adhesion on a layer of rust the method of grease. Oil film thickness can control the temperature of the rust or viscosity oil to achieve.

2) brush besmear of soaking or spraying shall not apply for the outdoor construction equipment or special shape of products, brush besmear is to pay attention to when do not produce accumulation, also want to pay attention to prevent leakage coating.

3) spray method and some big things can't rust by soaking method with oil, general use of about 0.7 Mpa pressure filtration of compressed air in the air clean place spraying. Spray method XiShiXing solvent for temporary or temporary thin layer, but must use perfect fire prevention and labor protection measures.
SKF bearing installation is correct, affecting precision, long life, a performance. Therefore, design and assembly department for the installation should fully SKF bearing. Hope according to the standard installation work. The project operation standard usually are as follows:

(1), cleaning SKF bearing and SKF bearing connection parts

(2), check the related parts size and finishing

(3), the installation of

(4), the installation of check after good SKF bearing

(5), supply lubricant

Hope that in the coming before installation, have open SKF bearing packaging. General grease lubrication, not to clean, direct filling grease. Lubricating oil, also need not ordinary cleaning, but, with the instrument or by SKF bearing etc, to wash with clean oil, remove coated in the bearings SKF rust. Remove rust SKF bearing, easy to rust, so cannot place no heed. Moreover, already sealing grease into the SKF bearing, not to clean use directly.

SKF bearing installation method, SKF bearing structure, cooperate because, conditions and different, generally, it is because for axis rotation, so inner circle over surplus to cooperate. Cylindrical holes SKF bearing, multi-purpose pressed into the press, or use hot charging method. Cone hole occasions, installed directly to the taper axis, or with the sleeve installation.

Installation to shell, with general clearance, outer ring had surplus quantity, usually with pressed into the press, or have after cooling method of installation with cold. With dry ice for cooling agent with the occasion of installation cold, moisture from the air will be condensed in the surface of the SKF bearing. So, need appropriate antirust measures.
