Maintenance Tips for Pressed Steel Bearing Units

1. Ensure the cleanliness of the installation surface and environment

If there are objects such as iron shavings, burrs, and dust entering the bearing, it will cause noise and vibration during operation, and even damage the raceway and bearing body. So, before installing bearings, we must ensure that the installation surface and environment are clean.

2. Proper cleaning

The surface of the bearing is coated with anti-rust oil. You must carefully clean it with clean gasoline or kerosene, and then apply clean, high-quality or high-speed high-temperature lubricating grease before installation and use the bearings. The cleanliness has a significant impact on the lifespan and vibration noise of bearings. But we would like to remind you that fully enclosed bearings do not require cleaning.

3. Fill in Suitable Grease

When lubricating bearings, the more grease you apply, the better, which is a common misconception. Excessive grease in bearings will cause excessive stirring of the grease, resulting in extremely high temperatures. The amount of lubricant filled in the bearing should fill 1/2 to 1/3 of the internal space of the bearing, and when the bearings run at high speeds, the grease should be reduced to 1/3.

4. Take Precautions When we install the Bearings

When we install or reassemble thermoplastic housing and bearing units,please take appropriate preventive measures to avoid damaging the bearings.To ensure that all surfaces in contact with the bearings are clean and free of debris. And we should use appropriate tools and techniques to secure the bearings in the right place and prevent them from becoming loose or damaged during we use them.

Process of Pressed Steel Bearing Units

1. Material selection

It is the first step in ensuring that a bearing will perform correctly and meet the operational requirements.

2. Cutting the steel pipe

The first step in producing ball bearings is cutting the steel pipe. Steel is an essential material for making ball bearings because it is strong and durable. The steel pipe is cut into small pieces known as blanks. These blanks will eventually become the spheres that are the most important part of a ball bearing.

3. Machining

It includes the processes of lathe and grinding. Lathes are used in the initial processing of the bearings by removing material from the object while grinding machines are used in the finishing process. We have the High precision machines to achieve tight tolerances and measurements which are required in producing quality bearings.

4. Heat treatment

After machining, the ring is heat-treated to improve its hardness, strength, and wear resistance. This is usually done through a process of quenching and tempering, which involves heating the ring to a high temperature and then rapidly cooling it.

5.Cleaning the rings

It is very important to clean the rings before assembling, as 1.Prolong the lifespan of the bearing.2.Prevent corrosion.3. Maintain the efficiency of the bearing 4. Reduce the risk of machine failure

6. Assemble bearings

When the rings are ready, we assemble with steel balls and a cage to form the complete bearing unit. The balls are between the two rings, to create a smooth and friction-free rotation.

7. Lubrication

Finally, the bearing is lubricated with grease or oil to reduce friction and wear.

8. Testing

After finished bearings, we will do various quality control tests to ensure bearings’ performance and durability. These tests can include measuring vibration, noise, rotation speed, load capacity and so on.

9.Marking items and brand

When the bearings are tested, we will mark items and brand on the rings, both customers' brand or our CTS brand are ok. We do the brands according to our customers' need.

10. Assemble bearing and housings

Assembling bearings and housings is a crucial step in the installation process. A poorly executed installation can lead to issues such as premature failure, increased friction, and noise. We have a team of professional workers who are experts in assembling these components to ensure that the whole bearings units are assembled with utmost accuracy and efficiency.

11. Making package

This process is extremely important as it ensures the safety and integrity of the mounted bearings during transportation and storage.

12. Delivery

we have a powerful system in place to ensure smooth and timely delivery of our products. We work with trusted shipping partners to ensure that our bearings reach our clients in the shortest possible time. We also offer various packaging options to ensure the safety of our products during transit.

Common Problems of Pressed Steel Units

Q: What steel is used for ball bearings?

A: 440C stainless steel and GCR15 chrome steel are the most common materials for precision miniature and instrument ball bearings.

Q: Is bearing steel stainless steel?

A: Chrome steel is the most commonly used material for bearings. It has slightly better low-noise characteristics than stainless steel. In addition, its hardness means that it has better load capacity than stainless steel bearings.

Q: What type of bearing lasts the longest?

A: Based on lifespan, the service life of ceramic ball bearings may be ten times that of steel bearings in the same motor. As compared with steel bearings, ceramic balls are less prone to expansion and vibration.

Q: Which bearing brand is best?

A: In 2023, the top ten bearing manufacturers in the world are Sweden SKF, Germany FAG, TIMKEN-USA, Japan NSK, Japan NTN, Japan NACHI, Japan KOYO, Japan NMB, and Japan IKO, accounting for approximately 75% of the world's harvest market.

Q: What is the strongest type of bearing?

A: Spherical roller bearings.
They usually have greater load-bearing capacity and stiffness than ball bearings. The spherical roller type can handle both axial and high radial loads.

Q: What is the purpose of a bearing housing?

A: Bearing housings support the bearings and protect them from contaminants while keeping in lubricant, and they can also house monitoring equipment. Essentially, they can help maximize performance, service life and cost-efficient maintenance of the bearing in it.

Q: Why are bearings made of steel?

A: Most ball bearings are made of chrome steel. This is because of cost and durability reasons. But bearings are also made of other materials, such as stainless steel, ceramics, and plastics.

Q: Does bearing steel rust?

A: Chrome steel ball bearings may rust. This is why bearings' outer surfaces are coated with protective oil when they leave the factory. Stainless steel bearings are more corrosion-resistant, but they still rust when in contact with certain substances.

Q: Do pillow block bearings need grease?

A: Pillow block bearings are important components in machinery that ensure smooth operation and minimize friction. However, having the correct amount of grease is crucial for its optimal performance and lifespan.

Q: Why use pillow block bearing?

A: Pillow block bearing supports shafts which run parallel to the installation surface. They are very simple but crucial components for conveying systems, industrial fans, farm equipment, boom cranes, car washing machines and more.
