The Advantages and Disadvantages of Fake and Low Quality Bearings
As the global economy continues to evolve, the cost of goods continues to rise. As manufacturers try to maintain costs, they may be tempted to use counterfeit or low-quality bearings in mechanized products and machines. While the upfront cost savings may seem attractive, counterfeiting and using low-quality bearings in parts can often lead to decreased performance and premature failure. In order to determine whether a bearing is genuine or a counterfeit, the following “Eight Black” features should be verified and examined:
1. Noise: Good quality bearings are very quiet when rotating. This can be checked by a vibration tester. Counterfeit bearings often have uneven rotational noises.
2. Performance: Genuine bearings are guaranteed to meet specific operational requirements and performance specifications as outlined by the manufacturer. Counterfeit bearings often have poorer performance, as the quality and materials used for the bearings are not of the original specs.
3. Dimensions: Genuine bearings are designed to meet specific dimensional specifications and tolerances. Counterfeit bearings may have slight differences in dimensions, including the diameter, inner and outer races, and ball size.
4. Clearance: Genuine bearings are designed to maintain a predetermined clearance at design points, which ensures optimal performance and life. Counterfeit bearings often have much higher clearance than specified, which can cause early failure or substandard performance.
5. Surface Finish: Genuine bearings are designed with a specific surface finish and precision machining. Counterfeit bearings often lack in this area, including poor finish, uneven surfaces, and improper machining.
6. Bearing Materials: Genuine bearings use high-quality materials that endure continuous use, including high quality and low-friction alloys, hardened steel balls, and coating. Counterfeit bearings often use cheaper materials that don’t provide the same quality or durability.
7. Markings: Genuine bearings bear identification markings that match the detailed information specified by the manufacturer. Counterfeit bearings lack in this area and are often not identified at all, or are marked incorrectly.
8. Packaging: Genuine bearings come in a standard package that includes paperwork and labels. Counterfeit bearings often lack any kind of package or labeling.
Utilizing genuine bearings in your products is key to providing years of optimal performance, life, and reliability. Whether you are responsible for specifying the bearing in a high-end sportscar or a local power tool, verifying the “Eight Black” points of bearings is essential in avoiding counterfeits, low-quality merchandise, and premature failure.
假货和劣质轴承的优缺点
随着全球经济的不断发展，物品的价格也在持续上涨。由于制造商试图维持成本，他们可能会被诱惑使用假货或低质量的轴承用于机械产品和机器。虽然一开始的成本节省可能看起来很有吸引力，但伪造和在部件中使用低质量轴承往往会导致性能下降和提前失效。为了确定轴承是真品还是假货，应先核实并检查以下“八大黑”特征：
1. 噪音：好质量的轴承旋转时非常安静。可以用振动测试仪检查。假货轴承旋转时往往有不均匀的噪音。
2. 性能：优质轴承被保证符合制造商指定的特定操作要求和性能规格。假货轴承的性能往往较差，因为质量和轴承使用的材料都不是原始规格。
3. 尺寸：优质轴承设计符合特定尺寸规格和容差。假货轴承的细微差异包括直径，内外圈和球的大小。
4. 清隙：优质轴承的设计保持设计点的预定清隙，以确保最佳性能和寿命。假货轴承通常比规定的更大，这可能会导致早期失效或性能不佳。
5. 表面处理：优质轴承设计时具有特定的表面处理和精密加工。假货轴承在这方面常常缺乏，包括粗糙的表面，不均匀的表面和不当的机加工。
6. 轴承材料：优质轴承采用能够持续使用的高质量和低摩擦合金，硬质钢球和涂层。假货轴承往往使用质量较差的材料，无法提供相同的质量和耐用性。
7. 标记：优质轴承上有与制造商详细规定的信息相匹配的标识。假货轴承在这方面缺乏，往往根本不被识别，或标记不正确。
8. 包装：优质轴承成套包括文件和标签。假货轴承往往没有任何类型的包装或标记。
在您的产品中使用真品轴承对于提供多年优异的性能，寿命和可靠性至关重要。无论您是要在高端跑车或当地电动工具中指定轴承，都需要检验轴承的“
