Bearing inner ring and the shaft is a tight fit to the outer shell for more loose with the available press IKO bearings first pressure mounted on the bearing, then the axis together with the bearing into the housing with press-fit bearing face a soft metal material on the pad assembly casing (copper or mild steel pipes). Assembly casing diameter should be slightly larger than the journal diameter, outer diameter should be less than the diameter of the bearing bore diameter of the ribs, so as to avoid pressure in the cage. A large number of bearing installation can add a handle on the casing.

Missing or can not use presses, you can use the assembly casing and small hammer to install the bearing. Impact force should be evenly spread to the entire circumference of the IKO bearing ring seal assembly bushing by hammering the end should be made spherical. Installation of the force required by the roller bearing and the bearing size and with the amount of interference related to the size, the amount of interference in large bearings commonly used in hot charging method. Bearing ring bearing or detachable hot charging into the tank or a dedicated heater uniformly heated to 80 to 100 ° C (should not exceed 100 ° C).

The bearings should be cleaned before installation. Installation, you should use special tools to auxiliary bearing straight and evenly pressed into, do not hand hammer percussion, especially the ban on direct bearing on percussion. When the bearing ring and bore with loose bore shall repair or replacement of IKO bearings, do not use to play in the bearings with surface pitting or pad copper barely. Roller Bearings Demolition should use the appropriate pull bearing Pull out bearing Do not use chisels, hand hammer percussion.

The advantages of the lubricating oil is small frictional resistance, and heat, mainly for speed and working environment of high temperature bearings. Grades of lubricating oil according to vehicle specification requirements to choose from, and then the vehicle maintenance cycle timely replacement, cleaning the organization to release the old oil with new oil, fuel should be added to the marking, or flush with the refueling port (as car specific structural requirements), not more.
Cause of the high bearing temperature: lubricant quality to meet the requirements or deterioration, lubricant viscosity is too high; institutions assembly tight (gap); bearing assembly tight; bearing ring rotation on the shaft or shell; overload ; the IKO bearing cage or rolling body fragmentation.

The reason of the roller bearing noise is more complex, one is the bearing inner and outer rings with surface wear. As a result of this wear and tear, destruction of the bearings and housings, bearings and axes with the relationship, leading to the axis deviated from the correct location, abnormal sound in the high-speed movement of the shaft. When the bearing fatigue, the surface of metal falling off, and also make the bearing radial clearance increases to generate abnormal sound. In addition, the lack of bearing lubrication, the formation of dry friction, and bearing broken and will produce an unusual sound. IKO bearings wear loose roll cage loose damage, also have abnormal sound.

Bearing rollers and outer ring raceway surface are under periodic pulse load, resulting in periodic changes in the contact stress. Reaches a certain value when the number of stress cycles, or the rolling element, the outer ring raceway surface fatigue spalling. If the bearing load is too large, will exacerbate this fatigue. In addition, IKO bearings is not properly installed, the shaft bending will produce the spalling of the raceway.

Roller bearing raceway and the roller contact surface uneven pits, indicating that the IKO bearings plastic deformation. The reason is that the bearings in a large static load or impact loads, the working surface of the local stress exceeds the material yield limit, this situation generally occurs in low-speed rotation of the bearing.
