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

Bearings are an important component in contemporary mechanical equipment, whose main function is to support the rotating body of the machinery, reduce the friction coefficient during its movement, and ensure its rotational accuracy. Rolling bearings generally consist of four parts: outer ring, inner ring, rolling element, and retainer. According to the shape of the rolling element, rolling bearings are divided into two categories: ball bearings and roller bearings.

(1) Based on the size and nature of the load     Large load or impact: Select roller bearings (line contact)     Low load or impact: ball bearing selection (point contact)(2) According to the direction of the load     Pure radial load: deep groove ball bearing, cylindrical roller bearing     Pure axial load: selective thrust bearing     Radial axial load: angular contact bearings, tapered roller bearings     Select deep groove ball bearings  when the axial load is not significant (3) Based on th

Recently, a large-scale international bearing exhibition was held in a large exhibition center. The exhibition attracted the participation of bearing manufacturers, suppliers, distributors and professionals from all over the world.Inside the exhibition center, various booths were set up with various types and specifications of bearing products, ranging from common deep groove ball bearings and cylindrical roller bearings to special customized bearings of various brands and models.

To successfully obtain valuable lunar soil, a series of key core technologies such as surface sampling and drilling are essential. Among them, surface sampling refers to using a robotic arm to carry a sampling device to shovel lunar soil or pick up lunar rocks at multiple positions on the lunar surface; Drilling is the process of using a drill rod to drill into the lunar surface at a predetermined depth and collect lunar soil core samples that maintain the "profile sequence".

From September 30 to October 5, 2024, Türkiye Machine Tool Exhibition will be held in Istanbul as scheduled.

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.
