As is known to us， the accurate maintenance of the sliding bearing is of great importance for the normal operation of the highway machinery。 If the maintenance of the sliding bearing is satisfactory， its service life can be prolonged。 In contrast， if the maintenance is not good， the service life will be seriously shortened and even the severe incident will happen。 In the normal situation， the working temperature of the lubricating oil can not surpass 50 Celsius degrees。 In addition， in order to ensure the abundant lubricating oil， the oil face should be inspected immediately and regularly。 In order to ensure the cleanliness of the oil， it is advised to change the oil timely。 What´s more， according to specific situations the problems of the sliding bearing should be analyzed in detail and solved immediately。 The common problems and its corresponding solutions are analyzed as follow:

(1) The sliding bearing is too hot。 If the lubricating oil is not enough， people should remember to add the oil and meanwhile remember to check whether the oil channel is unobstructed。 Besides， the bearing should be cleaned immediately and the oil must be replaced by the clean oil。 If the equipment is not in a good condition， the axle neck may be not straight。 For this problem， it is suggested that people should put a gasket under the bearing base。

(2) The axis is too hot。 If the rubber seal ring is too tight， the cover should be closed after the filling material is adjusted。 If there is friction between axis and bearing cover， the clearance between them should be adjusted as soon as quickly。 Generally speaking， the width of the clearance ranges from 0。25 to 0。3mm。

(3) There is oil on the surface。 If the oil pipe is blocked or the oil groove is too shallow， the pipe should be cleaned and the oil groove should be deepened。 What´s more， if the oil temperature is too low and the liquidity is too weak， it is advised to change the lubricating oil。 If the adjustable gasket blocks the lubricating oil， people must remember to inspectPlastic bearing the position of the adjustable gasket。
