How to Install the Roller Bearings

1. Install full roller bearings, generally using auxiliary sleeves. Auxiliary rollers or auxiliary sleeveholding the roll pin do not cause the roll pin to fall out, the shaft neck with its own chamfer will be lifted, with the roller bearing in the shaft neck slowly moving inwards, auxiliary roller or auxiliary sleeve will slowly exit, until installed to the working position. The outer diameter of the auxiliary roller and auxiliary sleeve should be 0.1-0.3mm smaller than the shaft diameter.

2. The rod bearing can also be installed in this way, that is, the auxiliary sleeve outside diameter coated with a thin layer of lubricant, into the bearing outer ring, so that the auxiliary sleeve and bearing outer ring constitute a ring hole, and then in the ring hole to install the rolling needle. After the roll pin is installed, the auxiliary sleeve can be rolled out with the working shaft.

3. For the roller bearing withno inner ring or no outer ring, when installed, the rolling surface of the shaft or housing hole can be coated with a thin layer of grease, and the rolling needle in turn close to the grease of the mounting area. There should be a gap when placing the last rod needle, the size of the gap in the rolling needle bearing on the circumference of 0.5mm is appropriate.

4. For the roll needle bearings with only the punching outer ring, because the outer ring wall is very thin, do not hit the installation with a hammer, should use a press pressure in. Because the pressure is uneven when the hammer is struck, it is easy to cause local deformation of the outer ring of the roller bearing.

When you know how to install the needle bearing, in the course of doing this work, you must be able to do it well. When to use the sleeve, where to coat the lubricant, can you hit with a hammer, how to load the rolling needle, etc. , all this after you understand the above introduction is no longer a problem, you can easily handle. Of course, practice is the most important thing, you only do, you can really learn from it.
