The combined needle roller bearing is equipped with thin and long rollers, so its radial structure is compact. Its inner diameter and load capacity are the same as those of other types of bearings, and its outer diameter is the smallest. It is especially suitable for the support results with limited radial installation size. How to install the combined needle roller bearing? Now let the manufacturer of combined needle bearing give you a detailed introduction!

The combined needle roller bearing should be installed according to the following steps:

1、The fully loaded combined needle roller bearing is generally installed with an auxiliary sleeve. The auxiliary roller or auxiliary sleeve holds the needle roller to prevent it from falling out, and the journal lifts the needle roller with its own chamfer. As the combined needle roller bearing moves slowly inward on the journal, the auxiliary roller or auxiliary sleeve will slowly exit until it is installed in the working position. The outer diameter of auxiliary roll and auxiliary sleeve shall be 0.1-0.3mm smaller than the shaft diameter.

2、The combined needle roller bearing can also be installed in such a way that the outer diameter of the auxiliary sleeve is coated with a thin layer of lubricating oil, the outer ring of the bearing is sleeved, so that the auxiliary sleeve and the outer ring of the bearing form an annular hole, and then the needle roller is installed in the annular hole. After installing the needle roller, push out the auxiliary sleeve with the working shaft.

3、For the combined needle roller bearing without inner ring or outer ring, apply a thin layer of grease on the rolling surface of the shaft or housing hole, and stick the needle to the grease on the installation position in turn. When placing the last needle, there should be a clearance of 0.5mm on the circumference of the needle bearing.

4、For the combined needle roller bearing with only pressing outer ring, as the outer ring wall is very thin, do not use a hammer to knock it for installation, but use a press to press it in. Because the pressure is uneven when hammering, it is easy to cause local deformation of the outer ring of the needle roller bearing.

The above is about the installation steps of the combined needle roller bearing. Zhihua is combined needle bearing manufacturer.
