Yoga takes you into the present moment. The only place where life exists.

Bronze bearing is wrapped by bronze strip. The material is made of particular formulation with high specific gravity and on its surface may be incorporated with spherical or diamond shaped indentations or oil grooves as required by customers.It is of high load capacity and long life.It can act as substitution of traditional bronze bushing for low cost and performance of anti-higher compact.It is widely used in hoisting machines, construction machines, automobiles, tractors, trucks, machine tools and some mining industry.

Self-lubricating Bearing Bushings Designs

Intentions are perfect. It started with customer needs and finally in customer satisfaction!
Quality – gaining confidence in the weight is the key to winning the competition, and is the starting point for infinite demand, value, and dignity.

Choose the bushing design material & environment

The most important factors to take into account when choosing the material and the surface finish of the counter surface on which the ring slides are the load conditions such as the load, the angle of oscillation, the type of movement and environmental influences.
If there is a risk of corrosion, the counter surface should be sufficiently resistant. Corrosion scars on the counter surface and, for example, abrasive particle contamination as a by-product of corrosion increase the surface roughness and accelerate wear. In these cases, the use of stainless steel or a surface treatment such as hard chrome, nickel plating, or electrolytic oxidation should be considered.

Related Self-lubricating Bearings Design PV value bearings

 Load Pressure P: Load pressure equals to the result gained by making the value of load pressure divide the vertical shade projected by the load-shouldering surface of the
bushing (Unit N/mm2).
Running Velocity V: Defined running velocity as the relative linear velocity against the mating surface (Unit: N/mm2).
PV Value Define PV value as the result gained by multiplying the load value P and the velocity V (Unit N/mm2-m/s).
Permissible PV value:Max permissible value shall be smaller than the value gained by multiplying the max permissible pressure and the max permissible velocity(Unit N/mm2-m/s).

2、Max permissible PV value
 The bushing can run for a short time when achieves its max PV value. It*s the running service ife requirement
that decides the requirement for tbe value. In bushing design, we require that the max permissible PV
value shall be smaller than the value gained by multiplying the max permissible load pressure and the max
permissible running velocity;

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.

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

Calculation assembled diameter

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

Maintenance after assembly

For the first running after bushing was fixed the bushing shaM be worked under situations of light load and low speed, which will have the following benefits:

1) Smooth the surface of the bushing and its mating axis and smooth the partial convex part that shoulder load.

2) Rectify fixing tolerance caused by bushing deformation; smooth the surface and increase contact surface.

Here are some situations in which self-lubricating and pre-lubricating bearings should be considered by a designer. The need to reduce maintenance or increase reliability is often encountered in practice. Inaccessible bearings in all types of equipment are ready candidates for self-lubrication, as are pieces of equipment in remote locations. By replacing metal bearings with self-lubricating bearings, substantial savings can be achieved. Likewise, self-lubrication can improve the useful life of equipment that should be neglected, such as consumer appliances.

Intentions, perfect. It began in customer needs, and finally customer satisfaction!
