7007 bearings and 6007 bearings are both commonly used in mechanical equipment, representing different bearing structures. In daily use, a small number of users cannot tell the difference between these two types of bearings and think that the two types of bearings can be used interchangeably. Is this really the case? As a senior bearing application engineer, Maxwell will analyze the differences between these two bearings in detail.
Can 7007 bearings and 6007 bearings be used interchangeably?
The answer is: not universal.
The dimensions of 7007 and 6007 bearings are the same, both are 35mm*65mm*14mm, but the structures are different. 7007 can be used in the occasions where 6007 is generally used, but 6007 cannot be used directly in the equipment that uses 7007 bearings. Due to various factors, VKUKEN does not recommend using 7007 bearings instead of 6007, which will increase the operation and maintenance costs of the equipment.
What are the differences between 7007 bearings and 6007 bearings?
Structural Differences
The 7007 bearing is a single-row angular contact ball bearing . An angle is designed on the inner and outer ring raceways. This raceway design determines that the 7007 bearing can bear radial and axial loads at the same time, and is more suitable for occasions that require axial positioning and high rigidity. The 6007 is a deep groove ball bearing, which mainly bears radial loads and has limited axial load bearing capacity. It is generally used in equipment with small loads and stable working conditions.
Applicable to different working conditions
7007 bearings can adopt different contact angles, such as 15°, 25° or 40°, and the models are 7007C, 7007AC, and 7007B respectively. Different contact angles have different bearing speeds and load bearing capacities, and they can still maintain good axial support capabilities at high-speed rotation. They are commonly used in high-precision mechanical parts such as CNC machine tool spindles, electric spindles, and power tool holders. However, 6007 bearings use smooth raceways and are not very adaptable to positioning accuracy and rigidity. They are more suitable for installation in ordinary industrial equipment such as motors, fans, and pumps.
Different prices
7007 Bearings have high requirements for craftsmanship and need to go through multiple grinding and super-finishing processes to ensure the contact angle and precision standards of the bearings. However, 6007 is different. The manufacturing process is simple and the cost is also low. Generally, the price of 7007 bearings is much more expensive than 6007. Unless the equipment needs to be modified , it is generally not recommended to replace the two .
7007 bearings and 6007 bearings are not interchangeable. The bearing structures of these two types are quite different, and their adaptability to working conditions is also different. In comparison, 7007 is more suitable for high-precision and load-carrying equipment, and is also an ideal choice for many important equipment.
Conclusion
When choosing bearings, you must follow the advice of the equipment manufacturer or bearing manufacturer, and do not make your own decisions. Two bearings that seem to be similar in model may have completely different structures and performances. If you cannot make an accurate judgment yourself, please contact us , and a professional bearing application engineer will help you.
