The installation of deep groove ball bearings will affect the accuracy, life and performance of sundry deep groove ball bearings. Therefore, please fully study the installation of deep groove ball bearings, that is, the installation of deep groove ball bearings in accordance with the operating standards including the following items.

1.Cleaning deep groove ball bearings and related parts 

　There is no need to clean the grease lubricated deep groove ball bearings and two sides with oil seals or dustproof covers. 

2.　There is no need to clean the grease lubricated deep groove ball bearings and two sides with oil seals or dustproof covers. 

3. Installation method 

The installation of deep groove ball bearings should be based on the structure of deep groove ball bearings, size and the matching nature of deep groove ball bearing components. The pressure should be directly added to the end face of the tight fitting ring, and the pressure should not be passed through the rolling body. The following method is generally adopted in the installation of deep groove ball bearings. 

A. pressure entry coordination 

The inner ring and shaft of the deep groove ball bearing are tightly matched. When the outer and deep groove ball bearing seat holes are loose, the deep groove ball bearing is first pressed on the shaft by the press, then the shaft is loaded with the deep groove ball bearing into the hole of the deep groove ball bearing seat, and the assembly sleeve is made of a soft metal material on the deep groove ball bearing. (copper or soft steel), the inner diameter of the assembly sleeve shall be larger than the Journal diameter, and the outer diameter shall be slightly smaller than the inner ring flange of the deep groove ball bearing to avoid pressure on the cage. Deep groove ball bearing outer ring and deep groove ball bearing seat tight matching, when the inner ring and shaft are loosely matched, the deep groove ball bearing can be pressed into the hole of the deep groove ball bearing seat first, and the outer diameter of the assembly sleeve should be slightly smaller than the diameter of the seat. If the deep groove ball bearing ring is matched tightly with the shaft and the seat hole, the inner ring and the outer ring should be pressed into the shaft and the seat hole at the same time. The structure of the assembly sleeve should simultaneously tighten the end face of the inner ring of the deep groove ball bearing and the outer ring. 

B. heating coordination
By heating the deep groove ball bearing or deep groove ball bearing block, the tight fit is transformed into a loose fit installation method by thermal expansion. It is a common and labor-saving installation method. This method is suitable for the installation of deep groove ball bearings with large interference amount. Before hot loading, the deep groove ball bearing or detachable deep groove ball bearings are evenly heated in the tank for 80-100 degrees, and then removed from the oil to the shaft as soon as possible to prevent the inner end of the inner ring and the shaft shoulder close after cooling, and the shaft of the deep groove ball bearing can be reacted again after the cooling of the shaft. Tighten. When the deep groove ball bearing is tightly matched with the deep groove ball bearing seat made of light metal, the heat loading method of the deep groove ball bearing seat can be used to avoid the abrasion of the matching surface. When heating deep groove ball bearings with the tank, there should be a net gate at a distance from the bottom of the box, or the deep groove ball bearing is suspended with a hook. The deep groove ball bearing can not be placed on the bottom of the box to prevent the impurities entering the deep groove ball bearing or uneven heating. The thermometer must have a thermometer in the tank, and the strict control of the oil temperature shall not exceed 10CTC. There is a tempering effect, which reduces the hardness of the sleeve.

C.Installation of deep groove ball bearing with conical hole 

The conical hole deep groove ball bearing can be directly mounted on the cone with a taper, or on the conical surface of the tight set and the retreating sleeve. The tightness of the match can be measured by the reduction of the radial clearance of the deep groove ball bearing. Therefore, the radial clearance of the deep groove ball bearing should be measured before installation, and the clearance should be measured frequently in the installation process to meet the needs. The clearance should be reduced to a minimum. When installing, the lock nut should be installed normally, and the heating installation method can also be used.

D.Installation of thrust deep groove ball bearing 

The coordination of shaft ring and shaft of thrust deep groove ball bearing is generally transition. The coordination of seat ring and deep groove ball bearing seat hole is usually clearance coordination, so this kind of deep groove ball bearing is easy to install, and the middle axis of the ball bearing of double direction thrust deep groove ball bearing should be fixed on the axis to prevent the rotation of the shaft relative to the shaft. The installation method of deep groove ball bearing, in general, is the majority of the axis rotation, so the coordination of the inner ring and the shaft is interference fit, the outer ring of the deep groove ball bearing and the deep groove ball bearing is the coordination of the gap.
