Bearing construction

Deep groove ball bearings have a simple structure and are easy to achieve high manufacturing accuracy compared to other types, making them easy to produce in series and in large quantities. The manufacturing cost is also low, and their use is extremely common. In addition to the basic type, deep groove ball bearings also have various variant structures, such as: deep groove ball bearings with dust covers, deep groove ball bearings with rubber sealing rings, deep groove ball bearings with stop grooves, deep groove ball bearings with large load capacity with ball loading notches, and double row deep groove ball bearings.

Bearing type

Deep groove ball bearings are mainly used to withstand radial loads, but they are also commonly used to withstand combined radial and axial loads. 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. The models of deep groove ball bearings include: deep groove ball bearings (60000 type); Deep groove ball bearings with stop grooves on the outer ring (60000N type); A deep groove ball bearing with a dust cover on one side and a stop groove on the outer ring on the other side (60000-ZN type); Deep groove ball bearings with dust covers on both sides and stop grooves on the outer ring (60000-2ZN type); Deep groove ball bearing with dust cover on one side (60000Z type); Deep groove ball bearings with dust covers on both sides (60000-2Z type); Deep groove ball bearings with sealing rings on one side (60000-LS and 60000-RZ types); Deep groove ball bearings with sealing rings on both sides (60000-2LS and 60000-2RZ types); Flange outer ring deep groove ball bearing (F60000 type); Flange outer ring deep groove ball bearing with dust cover on one side (F60000-Z type); There are 11 types of flange outer ring deep groove ball bearings (F60000-2Z type) with dust covers on both sides.

According to the size of deep groove ball bearings, they can be divided into:

(1) Micro bearings - bearings with a nominal outer diameter range of less than 26mm;

(2) Small bearings - bearings with a nominal outer diameter range of 28-55mm;

(3) Small and medium-sized bearings - bearings with a nominal outer diameter size range of 60-115mm;

(4) Medium and large bearings - Bearings with a nominal outer diameter size range of 120-190mm

(5) Large bearings - bearings with a nominal outer diameter size range of 200-430mm;

(6) Extra large bearings - bearings with a nominal outer diameter range of 440mm or more.

Processing form

The processing form of deep groove ball bearing parts is as follows:

1. Multi process processing: Generally, bearing production requires 20-40 processes, with more than 70 processes.

2. Forming processing: The working surfaces of bearing parts are all rotary forming surfaces, suitable for processing using the forming method.

3. Precision machining: The vast majority of the surfaces of bearing parts need to be ground, and the grinding dimensions and geometric accuracy are based on μ M is the unit.
