Stainless Steel Bearings

How to identify the quality of stainless steel bearings?   There are many manufacturers selling stainless steel bearings on the market now, and the quality of each manufacturer is also uneven. Faced with so many choices, how can we choose to buy high-quality stainless steel bearings? Let me explain to you how to choose good stainless steel bearings.   1. Look at the material. The stainless steel of stainless steel bearings can be seen from their hardness and precision. In this regard, good stainless steel bearings are much higher than inferior stainless steel bearings.   2. We can observe the stainless steel bearings with the naked eye to see whether the inner and outer raceways are in the shape of an arc groove, whether there are signs of peeling, and whether there are cracks and peeling on the rolling surface, and whether the entire structure is loose.   3. Identify by feel. Generally, the gap between the inner and outer rings and rolling elements of normal stainless steel bearings will not be too large. When we shake the inner race in our hands, see if it shakes significantly. If so, it is an inferior stainless steel bearing.   4. Rotate the stainless steel bearing. If it is not flexible enough and feels blocked during the rotation, or if the stainless steel bearing shakes during the rotation, it is also a low-quality stainless steel bearing.   5. As for the price, we must always believe in the saying that you get what you pay for. We cannot make our losses greater because of greed. If the price of the stainless steel bearing is much lower than the normal market price, then you should be careful. This may be a shoddy product, because the cost of stainless steel bearings is relatively high. If the price is too low, even the basic cost cannot be achieved. How can it be a truly good and high-quality stainless steel bearing?

Stainless steel bearings have the advantages of high temperature resistance, corrosion resistance, and greater stability. However, due to the different types of stainless steel bearings, the temperatures they withstand are also different. Today, we will mainly introduce the situations that will cause the temperature of stainless steel bearings to exceed the use range. 1. The stainless steel bearing and the journal are not evenly fitted or the contact surface is too small (the clearance is too small), and the specific pressure per unit area is too large. This situation mostly occurs after the new machine is tested or the bearing is replaced; use the coloring method to scrape the bearing to make its contact surface meet the requirements and improve the specific pressure per unit area; 2. The stainless steel bearing is skewed or the crankshaft is bent or twisted; adjust its clearance appropriately, check the bending and twisting of the crankshaft, and replace the crankshaft or repair it as appropriate; 3. The bearing quality is poor, the lubricating oil quality is inconsistent (low viscosity), or the oil circuit is blocked. The oil supply pressure of the gear oil pump is too low, and the oil supply is interrupted, causing the bearing to lack oil and produce dry friction; use bearings that meet the quality requirements, check the oil pipeline and gear oil pump, use lubricating oil that meets the quality requirements, and check and adjust the oil pump to make the pressure meet the requirements; 4. The stainless steel bearings have debris or too much lubricating oil, or the lubricating oil is too dirty. It is necessary to clean and replace new engine oil, and adjust the engine oil pressure; 5. The bearing has uneven excessive wear and needs to be replaced; 6. When the compressor is installed, the main shaft and the motor (or diesel engine) main shaft coupling are not aligned, and the error is too large, causing the two shafts to tilt. The concentricity of the two machines must be correct, and the leveling tolerance value must meet the value specified in the machine manual. When the compressor and the motor are connected with a rigid connection, more attention should be paid to alignment.
