Deep Groove Ball Bearings

Deep groove ball bearing with snap groove & snap ring on outer ring

Description：

The deep groove ball bearing with a snap groove and snap ring on the outer ring is a specific type of ball bearing designed to facilitate easy assembly and disassembly. The presence of the snap groove and snap ring simplifies the mounting and dismounting process of the bearing, as it eliminates the need for additional components or tools to secure the bearing in place. This design is particularly useful in applications where frequent maintenance or replacement of bearings is necessary, as it allows for quick and easy access to the bearing arrangement.

Deep Groove Ball Bearings Industry knowledge

Basic structural features of Deep Groove Ball Bearing with Snap Groove & Snap Ring on Outer Ring

1. Inner and outer ring structure
Deep groove ball bearings are mainly composed of inner ring, outer ring and balls. The inner ring fits tightly on the shaft and usually rotates with the shaft. The outer ring is installed in the bearing seat or housing to play a supporting and positioning role. The inner and outer rings are machined with arc-shaped grooves, which are used to accommodate balls. The radius of the inner ring groove is slightly smaller than the ball radius, while the radius of the outer ring groove is slightly larger than the ball radius. This design allows a certain amount of clearance between the ball and the groove to adapt to dimensional changes caused by factors such as thermal expansion, axial displacement or manufacturing errors.

2. Ball and cage
The ball is the core component of the deep groove ball bearing. It is located between the inner and outer ring grooves and bears radial and axial loads. The ball is usually made of high-hardness, high-wear-resistant materials to ensure that it can still maintain good performance under long-term high-load operation. In order to keep the balls in the correct position in the groove and prevent them from colliding with each other, a cage is usually installed in the bearing. The cage is usually stamped from steel plates, and its shape and size are precisely calculated and designed to ensure the uniform distribution and stable operation of the balls in the groove.

3. Buckle groove and outer ring snap ring
Deep groove ball bearings with buckle grooves and outer ring snap rings have a unique design in structure. The buckle grooves are usually located on one or both sides of the outer ring, and their shape and size are precisely designed to ensure that the snap ring can be tightly embedded in them. The snap ring is a single-mouth ring with a constant cross-section, and its material is usually an elastic material such as spring steel or stainless steel. During installation, the snap ring is compressed and embedded in the buckle groove, and then the bearing is fixed to the housing or bearing seat by its elastic restoring force. This design not only simplifies the installation process of the bearing, but also improves the axial stability of the bearing.

4. Sealing and dustproof structure
In order to further improve the performance and service life of deep groove ball bearings, some bearings are also equipped with sealing and dustproof structures. These structures are usually made of rubber or metal, and their shapes and sizes are customized according to the specifications and application scenarios of the bearing. The sealing and dustproof structures can effectively prevent dust, moisture and other contaminants from entering the bearing, thus keeping the bearing clean and dry. At the same time, they can also reduce the leakage and volatilization of lubricants, ensuring that the bearing remains in a good lubrication state during long-term operation.
