Sliding friction will cause fever to cause the bearing heat and damage

When the cylindrical bearing is installed, the mounting is not too tight, and the sleeve can be gently tapped into the appropriate position by a sleeve. The temperature of the open bearing heating should not exceed 120 ° C. The larger the push distance on the conical mating surface, the smaller the radial internal gap of the bearing, the smaller the amount of overcomes by measuring the amount of time or the axial advancement distance.

When you must install in a complex environment, pollution should be lowered. If tight sleeve and reticle sleeve, the oil hole oil tank has been processed, which can also be used to mount the bearing on a tight sleeve or unloading. Bearings after heating by acetylene spray gun, surface becomes black . Trace hammer directly knocking between housing apertures and bearing outer diameter surfaces, mounting the inner ring (or outer ring) non-standard bearing suppliers overbearing bearings, prohibiting the end surface of the bearing (or outer ring) end face with a hammer directly This is easy to knock on the bail.

The oil film separates the fitting surface so that the friction between the fitting surface is significantly reduced. The sleeve should be used on the end face of the inner ring (or outer ring), and the sleeve is tapped with a hammer. Small and medium-sized bearings can use the bearing mounting tool or preferably to advance the inner ring to the appropriate position on the conical axial diameter with a lock nut.

Try to be evenly active as possible when tapping, to prevent the bearing from tilting or skew. In the case of using a tight sleeve, a sleeve nut that can be locked with a hook wrench or impact wrench is used. When the mounting force is passed through the rolling body, the bearing of the inner ring interference fit is transmitted, and the force cannot be transmitted to the inner ring through the outer ring and the rolling.

Sliding friction will cause fever to cause the bearing heat and damage. When the heating temperature exceeds 727 ° C (the phase change temperature of the bearing steel), the metal phase tissue inside the bearing steel will change
