How deep groove ball bearings work

Deep groove ball bearings mainly bear radial load, and can also bear radial load and axial load at the same time. When it is only subjected to radial load, the contact angle is zero. When the deep groove ball bearing has a large radial clearance, it has the performance of an angular contact bearing and can bear a large axial load. The friction coefficient of the deep groove ball bearing is very small, and the limit speed is also high.

Bearing characteristics

Deep groove ball bearings are the most commonly used rolling bearings. It has a simple structure and is easy to use. It is mainly used to bear radial load, but when the radial clearance of the bearing is increased, it has a certain performance of angular contact ball bearing and can bear combined radial and axial loads. It can also be used to bear pure axial load when the rotational speed is high and the thrust ball bearing is not suitable. Compared with other types of bearings with the same size and size as deep groove ball bearings, this type of bearing has a small friction coefficient and a high limit speed. However, it is not resistant to impact and is not suitable for bearing heavy loads.

After the deep groove ball bearing is mounted on the shaft, within the axial clearance range of the bearing, the axial displacement of the shaft or the housing can be limited in two directions, so it can be axially positioned in both directions. In addition, this type of bearing also has a certain self-aligning ability. When it is inclined 2' to 10' relative to the housing hole, it can still work normally, but it has a certain impact on the bearing life.

Post code for self-aligning roller bearings

Install the tapered hole self-aligning roller bearings with the rear codes K and K30 on the matching locking sleeve to become the K+H and K30+H type bearings with the rear codes. This type of bearing can be installed on an optical shaft without a shoulder, and is suitable for occasions where frequent installation and disassembly of bearings are required. In order to improve the lubrication performance of the bearing, there is an annular oil groove on the outer ring of the bearing and three evenly distributed oil holes are drilled, with the post code W33.

What are the types of Deep Groove Ball Bearing?

Deep Groove Ball Bearing is mainly used to bear radial load, but it is also commonly used to bear radial and axial combined load. Especially when the speed of mechanical equipment is high and thrust bearings are not suitable, this bearing can be used to withstand bidirectional pure axial loads without maintenance during operation, making it a low-cost and widely used bearing. Deep Groove Ball Bearing models include: Deep Groove Ball Bearing (60000);

What are the characteristics of Deep Groove Ball Bearing?

After the Deep Groove Ball Bearing is installed on the shaft, the axial displacement in both directions of the shaft or housing can be limited within the axial clearance range of the bearing, so the axial positioning can be made in both directions. In addition, this type of bearing also has a certain degree of centering ability. When tilted 2 'to 10' relative to the casing hole, it can still work normally, but it has a certain impact on the bearing life.
