INA bearings early damage much more common than the bearing burnt, so INA bearing early damage prevention is important. INA bearing the correct maintenance are effective ways of reducing bearing early damage, is also a reliable guarantee for extended bearing life. Therefore, routine maintenance and repair of engines, must be taken to INA bearing alloy surface, the back, the appearance and shape at the tip and edge angles, such as abnormal or appear half an indication of wear, they find out the cause, and take the appropriate measures to improve the working conditions of INA bearing, attention to the prevention of early damage of sliding bearing
(1), improved INA bearing design and manufacturing processes
Design or when selecting bearings, taking into account the thermal balance to control the temperature of the bearings.
(2), improving the INA bearing maintenance and Assembly quality
Improving the quality of bearing hinge equipped with to ensure smooth no spot on the back of the bearing, position bump intact; amount of bounce off itself as 0.5-1.5mm, which is guaranteed to assembling rear axle w elastic through itself and the housing bore is close
(3), rational choice and add oil
In the use process to choose small surface tension of oil film of lubricant, forms a bubble collapsing oil flow reduces impact, can be effective in preventing cavitation INA bearing
(4), the correct use and maintenance of the engine
When installing the INA bearing should be specified in the movement of the shaft and bearing surfaces coated with grades of clean engine oil. After the engine bearings, refitted, before its first launch you should first turn off the fuel switch, starter drive the engine idling times, displayed when the engine oil pressure gauge and connect again, open the fuel switch and the throttle reset low speed, start the engine to run observation.
