Sliding Bearing Sliding Washer Selection Sleeve Bushing And Flanged Bearings Press Fit

We are leading Manufacturers of Dry Bearing, sliding bearing, boundary lubrication Bearing, Dry Bearing, Bronze Bearing, Bimetal Bearing, PTFE Bearing. Our Manufacturing Unit is located in china. The following are some of the specific applications of sliding bearings, Due to the combination of material properties and performance, VIIPLUS products have been more widely used and promoted than ordinary self-lubricating bearings. Thin-walled structure, small size, lightweight, easy to use PTFE sleeve BUSHES. Based on the material properties of the wear-resistant layer of PTFE mixture PLAIN BEARINGS products for difficult maintenance can not be refueled or difficult to refuel, with no oil lubrication and less oil lubrication occasions. During use, the PTFE mixture forms a transfer film that protects the grindstone shaft from biting. PTFE blends offer excellent wear resistance and low coefficient of friction, as well as moderate elastoplasticity, which distributes the stress across a wide contact surface and thereby increases the load-carrying capacity of sliding bearings products. Therefore, PTFE BUSHES products are suitable for rotating, Swing, axial sliding, and other occasions.

WASHER SIZE CHART

Bearing Press Fit
Roll Sleeve Bushings Detection

In the free state, there is a certain opening seam in the rolling shaft sleeve, so it is not possible to measure the outer diameter and inner diameter accurately.Therefore, the inner and outer diameters of rolling bearings should be equipped with professional measuring tools and equipment
Outside diameter detection
The shaft sleeve is forced into the ring gauge through gauge (maximum adding force 250N)
Use the same method and the same force to press the ring gauge end without passing
Inside diameter detection
When the shaft sleeve is pressed into the ring gauge, the through end of the plug gauge is applied with a small force, and the end of the plug gauge is applied with a greater force not exceeding 250N
Note: bushing pressure ring gauge, bushing outside diameter may be permanently reduced
Wall thickness measurement
Shaft sleeve wall thickness measurement: according to the height of the shaft sleeve in the shaft upward measurement point, two points or three points.
