The bearing ring raceway is the surface of the bearing workpiece, and its quality will directly affect the working performance and service life of the bearing. During use, we often find common quality problems on the surface of bearing rings. How do these quality problems arise? Based on years of experience, here are common quality problems and their causes on the surface of bearing rings.1.

Cast iron bearing seatAdvantages:Low cost: Cast iron materials are relatively inexpensive and suitable for situations with limited budgets.High hardness: In ordinary cutting processes, the hard and brittle nature of cast iron makes cutting easier.Suitable for low-speed, light load, and situations that do not require high-precision operation: The brittleness of cast iron may cause it to fracture when impacted, making it unsuitable for high-speed or heavy-duty environments.Disadvantages:Poor toughness: prone to rupture under heavy loads or high-speed operation.Not suitable for harsh environments

Annealing, also known as simmering, code name Th, is the process of heating a steel piece to Ac1 or Ac3 or above (30-50 ℃), holding it for a period of time, and then slowly cooling it (usually using furnace cooling).Normalization, also known as open flame, code Z, is the process of heating steel parts to Ac3 or Acm or above (30-50 ℃), holding them for a period of time, and then cooling them in air at a slightly faster cooling rate than annealing.The main difference between bearing annealing and normalizing is that normalizing is a deformation or special case of complete annealing, and the only

1、 Specific definition of bearingsBearings, known as the "food of the mechanical industry", are indispensable key components in modern mechanical devices. From high-speed cars and airplanes to common household appliances such as refrigerators, vacuum cleaners, and air conditioners in daily life, bearings play a crucial role. Its existence ensures the smooth operation of rotating components, thereby achieving efficient energy conversion and transmission.A bearing is a component that helps an object rotate.

Plastic bearings are very common in multiple application scenarios, including but not limited to the following areas:Automotive manufacturing:In the automotive field, plastic bearings are mainly used in automotive engines, transmission systems, suspension systems, and other parts. They can improve the performance and fuel economy of cars due to their good corrosion resistance, wear resistance, and lower friction coefficient. Especially in wheel and steering systems, the application of plastic bearings can reduce wheel weight and improve handling performance.

The 20th anniversary celebration of the 2024 Shanghai International Auto Parts, Maintenance, Testing, Diagnostic Equipment and Service Supplies Exhibition (Automechanika Shanghai) was successfully held from December 2 to 5, 2024 at the National Convention and Exhibition Center (Shanghai). The number of participating companies and visitors at this exhibition has broken previous records, fully demonstrating the important influence of Automechanika Shanghai as a professional service platform in the industry, and also reflecting the thriving development of the automotive industry.

How to install tapered roller bearingsAdjusting the axial clearance for the installation of tapered roller bearings can be achieved by adjusting the nuts, washers, and threads in the bearing seat holes on the shaft neck, or by using methods such as pre tensioning springs.
