Cone hole TIMKEN bearing can be directly mounted in the tapered shaft neck, and can also use tight set as a medium of removal, installed in cylindrical shaft neck, but in any case, tapered hole of the circle over surplus quantity can according to bearing clearance of the reduction is to determine.

Radial clearance reduction is namely bearing before and after installing radial clearance of the poor. Before installation should first know bearing the original radial clearance, install frequently measuring clearance, until it reaches to the ideal over surplus quantity of the corresponding radial clearance reduction is

Radial clearance reduction is measuring NSK bearings can also be used in the tapered shaft neck measurement of the quantity instead. So for the standard taper, radial clearance reduction is about equal to the amount of the axial 1/15, in this ratio, for solid shaft is concerned, with a surplus quantity of only 75% to 85% within a circle to the role of expansion.

Large spherical roller bearing and cylindrical roller bearing radial clearance reduction is usually with a feeler, pay attention to spherical roller bearing must respectively from two end measurement two columns roller in radial clearance, only two columns roller place clearance value is at the same time, to guarantee the inner ring and outer ring is relative.

Small cone hole for its SKF bearing radial clearance is too small and can not use a feeler, dial indicators can be used to measure the bearing shaft or contact with the ascension of the advancing volume, this time the attention is paid to the radial clearance quantity change, rolling body and groove elastic deformation will not add consideration, promote bearing or housing in the use of the force, and their weight should be roughly equivalent.

 
In large bearing them into remove set, can not only greatly saving, and particularly suitable for status restricted cannot use big hook spanner occasion. Specific operation is: will quench pad S at end of removal, nuts M lightly tighten, again will all along the circumference of cloth of hardened bolt K evenly tight until to obtain the clearance reduction is. Because of the cone by its removal from the friction locks, so even if the device is also does not take down loose, so that it is safe to take down nut M, convert fixed nut to replace, and will remove the set of pressure.
