轴承选择标准
额定
载荷 挑选轴承时，请检查额定载荷。这显示了轴承可以承受多大的力。您需要了解静态和动态负载能力。静载荷能力适用于轴承不运动时。动载荷能力适用于轴承运动时。制造商测试轴承以找到这些额定值。他们使用公式来猜测轴承可以使用多长时间。L10 额定寿命公式可帮助您了解轴承是否能够用于大多数用途。始终将径向和轴向载荷变成一个数字，以获得更好的结果。 - 轴承寿命已计算出适用于大多数用途。
- L10额定寿命公式使用动态容量和负载。
- 静载荷能力适用于轴承静止时。
- 动态负载能力在移动时进行速度和热量测试。
- 测试确保轴承能够承受载荷。
提示： 根据您的需求匹配额定负载，以阻止早期故障。
速度 - 选择轴承时，速度很重要。深沟球轴承可以走得非常快。小型轴承可达 30,000–50,000 RPM。大轴承通常保持在 10,000 RPM 以下，因为它们具有更大的摩擦力。特殊的混合或陶瓷轴承的转速可以超过 100,000 RPM。请务必检查速度等级以确保它符合您的需求。
- 小型轴承：30,000–50,000 RPM
- 大型轴承：低于 10,000 RPM
- 混合/陶瓷轴承：超过 100,000 RPM
注意： 使用轴承太快会使其过热并使其工作更差。
安装空间
您需要测量轴承的放置位置。深沟球轴承有多种尺寸。选择适合您空间的轴承。如果太大，就不适合了。如果它太小，它可能无法承受负载。在选择轴承之前，请务必检查尺寸。 - 测量您的空间。
- 将轴承尺寸与您的需求进行比较。
- 确保它适合以获得最佳效果。
不对中
不对中会损坏深沟球轴承。确保安装平台平整。轴承不应弯曲或倾斜。安装时，检查四个点的对齐情况，看看它们是否与制造商所说的相符。如果发现不对中，请修复表面或移动轴承。修复不对中可以阻止不均匀磨损和早期问题。 - 保持安装平台平坦。
- 检查偏移量。
- 测量四个点的对齐情况。
- 如果需要，修复表面。
提示： 良好的对中使轴承使用寿命更长，工作效果更好。
刚度
刚度是指轴承在推动时的刚度。您需要为需要精确的机器提供高刚性。静态刚度检查轴承在推动时弯曲的程度。动态刚度检查轴承停止晃动的程度。切割刚度着眼于切割时的工作原理。高刚性使弯曲保持较低，因此您可以获得更好的精度。它还可以停止晃动，从而提供更光滑的表面和更长的刀具寿命。 - 静态刚度：推动时弯曲的程度。
- 动态刚性：停止晃动。
- 切割刚度：切割时效果很好。
- 高刚性：精度更高，弯曲更少，刀具寿命更长。
运行噪音 运行噪音
会影响轴承的工作和感觉。您需要安静运行的轴承。良好的材料和光滑的表面降低了摩擦和噪音。精心制作可以保持尺寸正确，零件贴合良好。良好的润滑可降低摩擦和磨损，从而降低噪音。防护罩和密封件可防止灰尘进入和油污进入，帮助轴承安静运行。良好的设计和精心的建造也有助于降低噪音。始终以正确的方式使用轴承以实现安静运行。 - 使用好的材料。
- 仔细制作零件。
- 润滑良好。
- 使用防护罩或密封件。
- 仔细建造。
- 在限制内使用。
提示： C 代轴承使用特殊润滑来降低摩擦和噪音。
准确性 选择轴承时，精度非常重要。查看精度等级和公差等级。更高的精度意味着更好的工作和更少的晃动。较小的公差可提供更好的运行精度。较大的公差会导致空间不均匀和更大的晃动。选择正确的精度和公差等级有助于满足您的需求。选择正确的精度和公差非常重要。它使轴承使用寿命更长，工作效果更好。
| 精度等级 | 描述 | 对性能的影响 |
| P0 | 正常公差 | 标准性能 |
| P6 | 更高的精度 | 更高的准确性 |
| P5 | 更高的精度 | 更少的噪音和晃动 |
| P4 | 高精度 | 更稳定 |
| P2 | Very high precision | Best performance |
| C0 | Normal clearance | Standard load capacity |
| C2 | Less clearance | More load capacity |
| C3 | More clearance | Used for special jobs |
| C4 | Even more clearance | Used for special jobs |
| C5 | Most clearance | For high load jobs |
- Higher precision bearings make less noise.
- Smaller tolerances give better accuracy.
- Good tolerance ranges make bearings last longer.
Note: Picking the right accuracy and tolerance class makes sure your bearing works for you.
Lubrication
Lubrication helps your bearing run smoothly. Pick the right type for your job. Grease keeps out dirt and water and works for most bearings. Oil flows better and cools the bearing, so it is good for fast jobs. Grease thickness and type change how often you need to add more. Heavy loads or fast speeds mean you need to lubricate more often. Always match the lubricant to your job and temperature. | Error Type | Description |
| Misalignment | Wrong tools or crooked bearings cause uneven load. |
| Improper Tools | Using hammers instead of special tools causes mistakes. |
| Fit Issues | Too loose or tight fit hurts bearing work. |
| Identification | Bad wear and trouble turning show installation mistakes. |
- Use the right tools.
- Push with the right force.
- Line up bearing parts.
- Stop uneven wear and shaking.
Tip: Careful installation helps you get the best accuracy and tolerance from your deep groove ball bearing.
Matching Bearing to Application 
Specification Fit
You have to make sure the deep groove ball bearing matches your job. Check every detail before you choose. First, look at how close the parts fit together. You need to check the bearing load and how much it can hold. Make sure the bearing works for the speed you need. High-speed jobs need special accuracy and tight fits. Pick materials that work well where you use them. Always check if the parts fit together right. Use the right tools to put the bearing in place. This helps keep everything lined up. Think about how long the bearing should last. Plan for how you will take care of it. Seals and shields help the bearing work better and stay clean. The kind of lubrication and how much you use matters too. Adding more grease or oil and using special films helps keep the bearing working well.
Check how close the parts fit together
- Pick the right materials for your job
- Make sure the parts fit together right
- Use the right tools to install
- Plan for how long it should last
- Use seals and shields to help the bearing
- Choose the right grease or oil and how much
- Add more grease or oil and use special films
Tip: Always think about load, speed, and where you use the bearing before you pick one.
Environment
Where you use the bearing changes how it works. You need to watch out for heat, water, and dirt. High heat can make the bearing less accurate. Water and wet air can cause rust and hurt the bearing. Dirt and dust can wear out the bearing and make it not work right. Pick materials and grease that protect the bearing in your job. Seals and shields help keep out water and dirt. This keeps the bearing working well and accurate. Look at the table to see how each thing can change how long the bearing lasts. | Environmental Factor | Impact on Lifespan |
| Temperature | Can make the bearing wear out faster if you do not use the right materials or plans. |
| Moisture and Humidity | Can cause rust and damage, making the bearing wear out faster or break. |
| Contaminants | Can wear out the bearing and ruin the grease, making it fail. |
You should always plan for the right fit and accuracy in your job. This helps the bearing last longer and work better.

Common Mistakes
Overlooking Ratings
Some people think all bearings are the same. But ratings are very important. If you ignore load or speed ratings, your bearing may not last long. This can cause problems like: - Material fatigue
- Pitting and flaking
- Too much heat
- Early failure
Always check the load, accuracy, and tolerance ratings. These ratings help you pick the right bearing for your job. If you skip this, your bearing may break early. Your equipment might stop working.
Ignoring Environment
You must think about where you use your bearing. If you forget about the environment, you can hurt your bearing. Dust, water, or heat can lower accuracy and tolerance. Some jobs need special seals or materials. These protect the bearing. If you do not check the environment, you can lose accuracy. The bearing can get damaged. Always match the bearing to your job. Make sure it can handle the conditions.
Neglecting Maintenance
Taking care of your bearing is important. If you do not do maintenance, your bearing will not last as long. You might have problems like: - More money spent on repairs
- More stress from dirt inside the bearing
- Early failure from bad lubrication
- Missing signs like noise or heat
Watch your bearing for accuracy and tolerance. Clean and lubricate it often. This helps keep the accuracy and tolerance you need. Good care means your bearing lasts longer and works better.
Expert Advice
When to Consult
Ask an expert if you are not sure about your bearing. If you notice problems with accuracy or tolerance, get help. Experts check if your deep groove ball bearing fits your job. They look at load, speed, and fit. You might need advice if your bearing is noisy or does not last long. Sometimes your job changes, so you should check your ball bearings again.
