 There are three common installation of tapered bore bearings: 
 A bearing security in the conical journal 
 In this way, you can use the installation for small and medium-sized bearing sleeve can also use the locking nut and hook wrench bearing push the cone. But should preferably be using the lock nut installation, because it can precisely control the tapered bore bearing radial clearance reduction is shown in Figure 2-10.

 This method can take a similar approach, into locknut pressure. Withdrawal sleeves located between the journal and the bearing bore diameter, as shown in Figure 2-11. 
 Bearing mounted on an adapter sleeve 
 Installation, with the adapter nut bearing onto the conical adapter sleeve, as shown in Figure 2-12.

 This type of bearings used for machine tool spindle bearings such as NN3020K (original code 3182120). Its installation and conical bore self-aligning roller bearing installation is basically the same, in principle, with the degree of tightness by the install front and rear bearings radial clearance reduction is achieved. In the installation, the radial clearance reduction is generally by measuring the axial displacement of the bearing inner ring on the shaft instead. Axial displacement is calculated as follows: 
 L = K (eH-en + a) (mm) 
 Where eH - the original radial clearance 
 en - bearing assembly radial clearance 
 a - constant, 0.01 
 k - the scale factor with the hollow shaft wall thickness 
 k value and spindle bearings with diameter d, and the spindle with the journal The average diameter d. Related. K-values ??are shown in Table 2-8, eH values ??shown in Table 2-9, the en values ??shown in Table 2-10. When installing the bearing of the axial displacement can be used micrometer contact with the bearing inner ring face determination. 
 Department rely on two bearings, the outer spacer thickness adjustment. Make sure the two bearings, the thickness of the outer spacer: 
 The first one is the measurement 
 The first bearing on the round seat body, a weight equal to the pressure of A (pre-load), iron, bearing to eliminate the gap, the ball and the raceway to a certain degree of elastic deformation, and then measured with a dial indicator bearing The outer end of the size difference. Bearings installed for the sly back to deal with two bearings are measured within the wide face side of the outer dimension of the difference △ K1; deal with the two bearings are measured inside and outside of the narrow end side of the bearing relative to face to face (narrow end) installation, ring size difference △ K2; when the bearing is arranged in series, measured on a bearing of its wide end side of the inside and outside the ring size, the other bearing measurement side of the narrow end and outside the ring size difference. 
 Back to back installation of the bearing. This a bearing wide end at the outer dimension of the moment of +0. 07mm, the other bearing the wide end at the inside and outside the circle size difference of +0. 08mm inner spacer thickness, the thickness of 25mm, seek outside every other circle . 
 Outside the spacer thickness = 6. 25 + (0. 07 +0. 08) = 6. 40 (mm) 
 Measurement of size, each bearing measurement three times, the interval 120 ° measured once, and finally the mean value. 
 Figure 2-7 for a series arrangement of the installation of a pair of bearings. This measured a bearing wide end at the inside and outside the ring size difference is +0. 16mm, the other bearing the narrow end at the inside and outside the ring size difference is -0. 12mm, within the spacer thickness of 25mm, to seek outside spacer thickness. 
 Is separated from the ring thickness = 25 + (16-0 12) = 29 (mm)

 The second is the feeling of France 
 This method depends mainly on the practical experience to determine the internal and external spacer thickness. Common sense of law; First, the first outer cylindrical surface of the spacer 120 ° drill three diameter 2-3mm hole in both sides of the sleeve and paired according to their installation (back to back, face to face or series of sort) by adding inside and outside the spacer bearing the upper pressure equal to pre-load iron, and then use? small stick about 5mm, sequentially through the three holes touch the spacers, check inside and outside the spacer between both ends of the surface resistance. By hand feeling, both inside and outside spacer resistance should be similar, or grinding the end of the spacer. Second, the left middle finger and index finger pressed the two sets of bearings (approximately equal to 50 pre-load) to eliminate all of its clearance, right hand refers to toggle within and outside the spacer, to determine the resistance is similar. Third, with the thumb and index finger of both hands clenched the two sets of bearings, eliminating all of its gap with one hand middle finger inserted into the bearing bore, toggle to put the original partial within the spacer, and check its resistance and the outer ring is similar.
