淮安SKF轴承是机械的重要组成部分。为了保证机器的正常运转，轴承是必不可少的。
Huaian SKF bearing is an important part of machinery. In order to ensure the normal operation of the machine, bearings are indispensable.
因此，轴承材料尤为重要，同时也影响轴承的使用寿命。
Therefore, bearing materials are particularly important, but also affect the service life of bearings.
轴承由特殊轴承钢制成。坚硬、耐用、坚固，能够承受比自身尺寸大几倍的部件。
Bearings are made of special bearing steel. Hard, durable, strong, able to withstand parts several times larger than their own size.
轴承钢用于制造滚珠、滚子和轴承环。轴承钢具有较高且均匀的硬度、耐磨性和高弹性极限。轴承钢中非金属夹杂物和碳化物的化学成分、含量和分布均匀性非常严格，是所有钢生产中**严格的钢种之一。1976年，国际标准化组织（ISO）将一些等级的通用轴承钢纳入了国际标准。淮安SKF轴承钢可分为四类：全硬化轴承钢、表面硬化轴承钢、不锈钢轴承钢和高温轴承钢。
Bearing steel is used to manufacture balls, rollers and bearing rings. Bearing steel has high and uniform hardness, wear resistance and high elastic limit. The chemical composition, content and distribution uniformity of non-metallic inclusions and carbides in bearing steel are very strict, and they are one of the most stringent steel grades in all steel production. In 1976, the International Organization for Standardization (ISO) incorporated some grades of general bearing steel into international standards. Huaian SKF bearing steel can be divided into four categories: fully hardened bearing steel, surface hardened bearing steel, stainless steel bearing steel and high temperature bearing steel.
轴承钢的特点是什么？今天，常州轴承代理二瑞小戴将向您介绍轴承钢的特点。
What are the characteristics of bearing steel? Today, Errui Xiaodai, Changzhou Bearing Agent, will introduce to you the characteristics of bearing steel.
一、接触疲劳强度
I. Contact fatigue strength
在周期性载荷作用下，轴承容易发生疲劳损伤，即裂纹和剥落，是轴承的一种重要失效形式。因此，为了提高轴承的使用寿命，轴承钢须具有较高的接触疲劳强度。
Under periodic load, bearing is prone to fatigue damage, that is, crack and spalling, which is an important failure form of bearing. Therefore, in order to improve the service life of bearings, bearing steel must have high contact fatigue strength.
二。耐磨性
Two. Wear resistance
在淮安SKF轴承的工作过程中，轴承环、滚动体和维修机构之间不仅会发生滚动摩擦，还会发生滑动摩擦，使轴承零件始终处于磨损状态。为了增加轴承零件的磨损，保持轴承的精度和稳定性，延长使用寿命，轴承钢应具有良好的耐磨性。
During the working process of Huaian SKF bearing, not only rolling friction but also sliding friction will occur between bearing ring, rolling element and maintenance mechanism, which makes the bearing parts always in wear state. In order to increase the wear of bearing parts, maintain the accuracy and stability of bearings, and prolong service life, bearing steel should have good wear resistance.
三。硬度
Three. hardness
硬度是轴承质量的重要指标之一，直接影响接触疲劳强度、耐磨性和弹性极限。轴承钢在工作状态下的硬度应达到HRC61~65，使淮安SKF轴承获得较高的接触疲劳强度和耐磨性。
Hardness is one of the important indexes of bearing quality, which directly affects contact fatigue strength, wear resistance and elastic limit. The hardness of bearing steel should reach HRC61 ~ 65 in working condition, so that Huaian SKF bearing can obtain higher contact fatigue strength and wear resistance.
四、防锈性能
IV. Antirust Performance
为了避免轴承零件和产品在加工、发送和使用过程中的腐蚀和生锈，要求轴承钢具有良好的防锈性能。
In order to avoid corrosion and rust of bearing parts and products in the process of processing, sending and using, bearing steel is required to have good anti-rust performance.
处理性能
Processing performance
在消耗过程中，轴承零件**须经过许多冷热工序。为了满足小批量、高*效率和高质量的要求，轴承钢应具有良好的加工性能。如冷热成形性能、切削性能、淬透性等。
In the process of consumption, bearing parts have to go through many hot and cold processes. In order to meet the requirements of small batch, high efficiency and high quality, bearing steel should have good processability. Such as cold and hot forming performance, cutting performance, hardenability and so on.
轴承钢除满足上述基本要求外，还应满足适当的化学成分、平均外部结构、较少的非金属杂质、符合外部缺点规范且不超过外部脱碳层常规浓度的要求。
In addition to meeting the above basic requirements, bearing steel should also meet the requirements of appropriate chemical composition, average external structure, less non-metallic impurities, conforming to external shortcomings specifications and not exceeding the conventional concentration of external decarbonization layer.
简要介绍了淮安SKF轴承钢的特点。我相信你对轴承钢有一定的了解。
