MAINTENANCE SELF-LUBRICATING DESIGN BUSHING’S DIMENSION
1、Inside diameter of the bushing
The inside diameter of the bushing depends on the diameter of its mating axis.
2、Length of the bushing
The length of the bushing depends on the size of the pressure-shouldering surface.
The longer the bushing, the less pressure at the surface, for the longer bushing, the load on the bushing is relatively lessened- But simultaneously, it may result in deviation contact or lower cooling efficiency and thus shorten the service life of the bushing. On the contrary if the length of the bushing is too short, lubricating grease may quickly flow out of the bushing. Therefore, it hardly forms a grease film and capability of the bushing is accordingly debased.
3、Bushing thickness
The main advantage of standard composite self-lubricating bushings rest with their thin wall thickness.
Standard bushings thickness can be 0.5mm, 0.75mm, 1.0mm, 1.5mm, 2.0mm, 2.5mm.
Self-lubricated Bushings Design Design of the Mating Axis
Surface roughness, hardness and plating of the mating axis will have great influence on the capability of the self-lubricating bushing. High-quality surface of the mating axis can prolong the life of the bushing while rough surface will shorten the life of the bushing.
1、Surface roughness of the mating axis When self-lubricating bushings being used in the condition of fluid lubrication and the surface of the mating axis is rough, the convex points on the bushing and its axis will cut the oil film and thus the surface of the axis and the bushing will directly contact with each other therefore, to improve the capability of the bushing, it requires polishing the surface of the mating axis as smooth as a mirror; thus can reduce the clearance of the oil film and make the film work well For most self-lubricating bushings applied in the condition of dry friction or marginal lubrication^ controlled roughness from 0.32 to 1.25 is acceptable and there is no need ta polish the surface of the mating axis as smooth as a mirror.
2、Hardness of the mating axis If there is no hard article in the lubricating condition, good performance can be achieved by using bushing materials and hardness recommended in the following form. If not, it would be better to use the harder material for the mating axis.
Self-lubricating Bushings Design
Interference for bushing fixing
With the exception of being burnt, the service life of self-lubricating bushing depends on the abrasion degree of the bushing’s inner diameter. In conditions like dry friction, boundary lubrication and oil lubrication, the abrasion of the same bushing will be different Main factors that may influence the service life are character and direction of the load, lubrication condition, running speed, environment temperature, hardness of the mating axis, roughness of the mating surface material of the mating axis, air quality around etc Therefore, it’s difficult to calculate the actual abrasion quantity. Regardless the factors like influence from the load and speed, difference caused by running direction, kinds of lubricating oil, mating clearance, roughness and impurities penetration degree, the abrasion W can be calculated by the following formula.

Interference for bushing fixing
Before the bushing is pressed into the housing: as the outside diameter of the bushing is bigger than the inside diameter of the housing, strong pressure can be available in the housing. And also this kind of fixing can assure the roundness of the bushing and make the bushing well fixed avoiding abrasion caused by sliding of the bushing in the housing. The interference can be calculated by the following formula:
Min interference Min OD of the bushing-Max ID of the housing
Max interference Max OD of the bushing-Min ID of the housing
Simplified assembly for self-lubricating bearings
After bushing mounting, providing that there is no expansion of the housing, the calculation can be carried out by the following formula.
Min ID of the bushing d=Min ID of the housing D-2 x Max thickness of the bushing
Max ID of the bushing d=Min ID of the housing D-2 x Min thickness of the bushing
