From the color of the coupling can see the material and quality of the coupling

Porous metal material: Porous metal is a powder material, it has a porous tissue, if it is immersed in the lubricating oil, so that the pores filled with lubricating oil, has become a self-lubricating oil bearing performance. Porous metal materials, small toughness, only suitable for smooth impact-free load and medium and small speed situations.
Coupling plastic: commonly used plastic bearings are phenolic plastic, nylon, PTFE, plastic bearings have greater compressive strength and abrasion resistance, available oil and water lubrication, but also self-lubricating properties, but poor thermal conductivity. Bearing the appearance of color can fully reflect the bearing product material situation, for most counterfeit bearing products, are generally in the steel selection of the context. As we all know, the price of steel is also an important factor that determines the price of bearing products. Therefore, some unscrupulous merchants use the following articles in the steel industry. For example, it is to reduce the type of steel to shoddy goods. The use of ordinary steel, carbon steel, steel and other materials Ma, what is more, will use iron pipe to replace steel products. Therefore, the color of the coupling with the authentic product is very different, most of these low-cost materials in the appearance of white color, green with the bearing steel has a more obvious difference.
Before and after the bearing is installed, the method of measuring radial internal clearance with a feeler gauge is suitable for large and medium-sized spherical and CARB bearings. It is best to measure the clearance between the outer ring and the unloaded roller. Measuring the locking nut's tightening angle is a proven and effective method that can be used to determine the correct over-centering of small and medium-sized bearings on tapered journals. Tightening angle a guideline values have been established to help accurately locate the bearing on the tapered journal.
