How to Choose the Self lubricating bearing oil?2020-03-31T10:07:09+00:00

How to choose the lubricating oil from the bearing, blind choice of lubricating oil: lubricating oil plays the role of lubrication, cooling, cleaning and sealing. The quality of lubricating oil is directly related to the service life of the engine. Oil blackening is oil deterioration: engine oil is working in a more demanding high temperature conditions, easy to oxidize deterioration, produce acidic substances and superposition into polymer sediments, so as to destroy the lubrication. Diesel car oil: gasoline engine oil and diesel engine oil. Although gasoline engines and diesel engines work under the same conditions of high temperature, high pressure, high speed and high load, they are still quite different.

A bushing is one category of plain bearings.

A bushing is a thin walled bearing metal steel backed alloy layer with lubricated or bronze bushing sleeve that allows relative motion by sliding bearings, as compared to rolling. A bushing might also be called a sleeve bearing. However, the term sleeve bushing would be redundant. Thus, a bushing is a plain bearing, but a bearing is not necessarily a bushing type.

A bearing is the general term for something that allows relative motion between two components, surfaces, etc.

How To Check The Bushing Dimensions & Size?2020-04-03T15:00:43+00:00

Technical reference bearing size inspection, Diameter, thickness,Measure bushings with a flange, Measure bushings. Find your bushing size, ISO 3547/DIN 1494 Steel-bronze-PTFE composite bushing

Bearing size inspection
Rolled products production system determines the life of the seam establishing, make product in unfastened circumstance now not desirable roundness, and collar diameter and hole for surplus, among shaft sleeve to maximize to adapt to the form of hollow, consequently can not be without delay measured below loose state product diameter and must use a unique measuring tool and gadget a good way to detect; ISO3547 well known component 2 specifies the tolerance check for rolled up merchandise, such as:
Test approach A: out of doors diameter of huff gauge;
• inspection technique B: test outdoor diameter with forestall-gauge;
• test method C: take a look at the internal diameter with forestall gauge;
• inspection approach D: the measuring ruler shall be used to look into the outer diameter of large-sized merchandise and the wall thickness inspection approach shall be used in preference to the inspection method c. The wall thickness inspection technique and the inspection approach C shall now not be used on the equal time.

Outer diameter check technique
Take a look at method (iso3547-2)
The upper and lower huff gauge including the right view is used to check out the outer diameter. At some point of the inspection, the open seam of the product faces as much as the huff gauge to apply the inspection load Fch, which enables the rolled axle sleeve to be placed within the inspection mold in a way that meets the necessities. Within the take a look at, the outer diameter of the roll sleeve will decrease because of elastic deformation, however it’s going to no longer produce permanent deformation. The outer diameter of the product can be calculated via checking the change inside the distance between the dies, delta z.
Check technique (iso3547-2)
ring gauges are adopted for inspection, particularly the thru gauge and the forestall gauge. The shaft sleeve can be pushed into and through the through gauge with the maximum pressure of 250N by hand. Not able to go into and skip the stop below the same situations. In some instances, the check accuracy may be affected, as an example, the axle sleeve isn’t always round or the force of the closed open seam itself has handed 250N. Presently, it’s miles endorsed to undertake the test method A or the check technique combining the dimension of compression pressure and wall thickness.
Test approach  (iso3547-2)
Adopt the correct measuring ruler to degree the outer diameter, usually for the large specification of shaft sleeve outer diameter detection.

Diameter test technique
Test technique
Take a look at the internal diameter of the bushing after urgent the bushing into the reference ring gauge. In attention of sensible use, it’s far commonly recommended to adopt the test of via and prevent-plug gauge. At the moment, the via end plug gauge can skip via the inner hole of the axle sleeve when the most thrust of the hand isn’t any more than 250N, and the forestall plug gauge have to now not pass via the internal hole of the axle sleeve underneath the equal occasions. When the bushing is pressed into the reference ring gauge, the outer diameter of the bushing may cause everlasting deformation and can not be used commonly.

Test approach for thrust washer
In addition to the thickness tolerance, the parallelism of the gasket is equally important to the lifestyles of the gasket and the damage. We use a extra powerful take a look at approach to locate the parallelism of the gasket. Of route the parallel block must be larger than the gasket itself.

Wall thickness detection approach
As an opportunity to test approach C, the 2 methods can not be used at the equal time. The wall thickness is measured inside the axial course according to the axle sleeve size.measure bushings Bearing-size-inspection

What is PTFE Polytetrafluoroethylene for Bearing Bushings?2020-04-06T12:30:34+00:00

Polytetrafluoroethylene (commonly referred to as “non-stick coating” or “easy to clean material”); It is a kind of synthetic polymer material which USES fluorine to replace all hydrogen atoms in polyethylene. This material has the characteristics of anti – acid, anti – alkali, anti – various organic solvents, almost insoluble in all solvents. At the same time, polytetrafluoroethylene has the characteristics of resistance to high temperature, its coefficient of friction is very low, so it can be used for lubrication, also became an ideal coating for easy to clean wok and water tube lining.

Ptfe is called “plastics king”, the father of fluorine resin Roy Planck, in 1936 began the study in the United States dupont, substitute of freon, they collected some tetrafluoroethylene stored in cylinders, ready for the next day on to the next step of the experiment, but when the second day after open the cylinder pressure reducing valve, but no gas overflow, they thought it was flat, but will the cylinder weighing, found that the cylinder did not lose weight. They sawed open the cylinder and found a large amount of white powder, which was polytetrafluoroethylene.
They discovered that ptfe was so good that it could be used as an anti-fusion sealing gasket for atomic bombs, artillery shells, etc., that the U.S. military kept the technology secret during world war ii. It was not declassified until after world war ii, and industrial production of ptfe was achieved in 1946.
Chinese name “teflon” (teflon). It is composed of tetrafluoroethylene by polymerization of polymer compounds, its structural short form for – – CF2 – CF2 – n -, it has excellent chemical stability, corrosion resistance, corrosion resistance in the world today is one of the best materials, in addition to the three fluoride molten alkali metals, chlorine, five liquid chlorine and fluoride, fluoride can all other chemicals, boil in aqua regia doesn’t change, is widely used in all kinds of resistance to acid and alkali and organic solvent. Has the sealing property, the high lubrication non-stickiness, the electric insulation property and the good anti-aging ability, the temperature resistance is excellent (can work under the temperature of +250℃ to -180℃ for a long time). Ptfe itself is not toxic to humans.
The operating temperature is -190 ~ 250℃, allowing sudden cooling and sudden heating, or alternating cold and hot operation.
