Replace the bearing technology
 

(1) power works together as much as possible through the axis of the SKF bearing, which requires the screws evenly symmetry and smooth, by spherical or parallel to the axis force application.
(2) the size of the wire should be smooth and uniform, unfavorable impact, this request can use hydraulic or use steady pull or pressure tool, it had to use hammer, also want to through soft without exfoliation metals such as copper sleeve to buffer, tapping force as gently as possible. It is best to use copper or copper hammer hammer.
Separated type thrust ball bearing is a bearing, shaft ring, can seat and cage, ball component separation. Shaft is made to match the shaft ring, a circle is to match the bearing hole of the ring, and there are gaps between shaft.
(1) the basic thrust ball bearings
Basic thrust ball bearing can be divided into: one-way thrust ball bearing with flat; Bidirectional thrust ball bearing with flat; One-way thrust ball bearings with spherical radial load; With a spherical seat one-way thrust ball bearings; Bidirectional thrust ball bearing with spherical seat.
Thrust ball bearings can only carry axial load, one-way thrust ball bearings can only carry axial load in one direction, two-way thrust ball bearings can withstand axial load in two directions.The installation of thrust bearing h t t p:/ /fagbearings.over-blog.c o m/2014/05/the-installation-of-thrust-bearing.h t m l
Thrust ball bearing can't limit shaft radial displacement, limit rotational speed is low. One-way thrust ball bearing can limit the one direction of the axis and shell of axial displacement, two-way bearing can limit the axial displacement of two direction. When the shaft and bearing hole axis misalignment, will cause the steel ball component radial runout on the ring channel, make the premature bearing failure. Don't point that we need to pay special attention to SKF bearing leads to premature failure, not what, lost what's the use effect, you just have a piece of gold lost its effect also will become a waste. And you are not gold, but sooner or later, if you really gold will shine, like SKF bearing, SKF bearing light all over the world now.
Thrust ball bearing in the operation, due to the effect of inertia force of the steel ball and cage, cause the relative sliding between the ball and the channel edge, increase the bearing temperature rise, affect the bearing of the normal operation. In order to prevent excessive sliding occurs, must keep bearing in operation often have minimal axial load Famin.
(3) avoid by applying pressure roller, which requires inner ring (circle) shaft installation when applying pressure through the inner ring and outer ring installation) by outer force application.
(4) the degree of drag force continued to be, for example, when installing a bearing in the bearing fit into the correct position to stop work, to ensure that the rings (washers) face rely on a hole or shaft shoulder end, neither packed too tight, nor does not reach the designated position.
