The old fashioned way machine hollow shaft mounting rolling bearings is to be processed into the inner diameter of the hollow shaft for the bearing, bearing heating device, bearing parts, the inner bearing ring outer Covered sets, set against out of the feed screw top tube (or out of liner material ) bolted to the hollow shaft be pressed. During the grinding operation, access to materials spiral tube, often loose mounting bolts, resulting in a top cover and a hollow shaft displacement, dust will air from the gap between the shaft and the top of the sleeve into the bearing box, the grease dirty, It has occurred leading to poor lubrication, resulting in damage to the phenomenon of the bearing.

To overcome these several disadvantages, we have gone through years of practice and exploration, devised a new method of installation, and in some manufacturers use to get a good application.

The method is: the site of installation Rolling mill hollow shaft diameter bold, hollow shaft of light oil is cooled in turn transmitted to the hollow shaft bearing temperature falls within the normal range of 60 degrees or less.

The advantage of bearing the following aspects:

1. The oil lubrication grease lubrication superior to that minimize bearing friction coefficient, better energy-saving effect. {HotTag}

2. The normal operation of the bearing temperature, than dry oil lubricated bearings temperature is much lower, extending bearing life.

3. Bearing Xiazuo has oil sight oil standard, the operator can always see the oil level, it is possible to replenish the oil, and prevent starvation and poor lubrication, avoid the occurrence of bearing damage accident.

The oil content of oil bearing compartment, can be mounted rolling bearing reduced outer diameter (in and out equipment installation to ensure there is enough strength and torque strength of the premise), hollow shaft and out of the end surface of the material to set up a spiral tube coupling flange, and access to materials spiral tube flange connection. In the hollow shaft by the rough surface of the tapered end, set up a pinch collar flange bearings prevent bearing axial sprang.
