  Types of Turbocharger Bearings

  What is a turbocharger? Turbochargers, which are common in automobiles, are an air compressor that increases the amount of air intake by compressing air. It uses the inertia of the exhaust gas from the engine to propel the turbine in the turbine chamber. The turbine drives the coaxial impeller. The impeller pressurizes the air sent from the air filter pipe to pressurize it into the cylinder. When the engine speed increa...

  Factors Affecting The Life of Angular Contact Ball Bearings

  The shaft parts of CNC machine tools, such as machine tool spindles, are generally assembled into thrust ball bearings and rotate at high speeds, which sometimes generate high heat. If this heat is not discharged promptly, it will cause angular contact ball bearings to overheat and cause the temperature of the corresponding parts of the CNC machine tool to rise, resulting in thermal expansion. When it is more serious, the sp...

  What Factors Should Be Considered When Selecting Cylindrical Roller Bearings

  Cylindrical roller bearings with spacers and raceways are linear contact bearings. Load capacity, mainly bear radial load. The friction between the rolling element and the collar of the ferrule is small, which is suitable for high-speed rotation. Depending on whether the ring has ribs, it can be divided into single-row cylindrical roller bearings such as NU, NJ, NUP, N, NF, and double-row cylindrical roller bearin...

  Do you know that the earliest bearings appeared more than two thousand years ago?

  An early form of linear motion bearing was a row of wooden poles under a row of skid plates. Modern linear motion bearings use the same working principle, but sometimes balls are used instead of rollers. The most straightforward rotary bearing is a bushing bearing, which is just a bushing sandwiched between the wheel and the axle. This design was subsequently replaced by rolling bearings, which replaced the original bushings...

  Single row cylindrical roller bearings: traditional industry has new wisdom

  We often say that don’t look at each other for three days. The truth is understandable, but when they act, they tend to preconceive inherent stereotypes. This is the case for everyone, and so is the country, and some German industrialists have said firmly: China can never make our cylindrical roller bearings with gaskets. As a result, Professor Neil Ferguson of Stanford University in the United States issued an article a...
