Deep groove ball bearing

Deep groove ball bearings are the most representative rolling bearings. Compared with other types of bearings of the same size, this type of bearing has low friction coefficient, high limit speed, simple structure, low manufacturing cost, high precision, no need for frequent maintenance, large size range and many forms, and it is the most widely used type. Bearing. It mainly bears radial load and can also bear certain axial load. When it only bears radial load, the contact angle is zero.

After the deep groove ball bearing is installed on the shaft, within the axial clearance of the bearing, the axial displacement of the shaft or the housing can be limited, so it can be axially positioned in both directions. When the deep groove ball bearing has a larger radial clearance, it has the performance of an angular contact bearing and can bear a larger axial load. Under high-speed operating conditions with large axial loads, deep groove ball bearings are more advantageous than thrust ball bearings. In addition, this type of bearing also has a certain degree of aligning ability. When it is inclined 2'～10' relative to the housing hole, it can still work normally, but it will have a certain impact on the life of the bearing.

Angular contact ball bearings

Generally speaking, the six types of bearings represented by 36 and 46 type bearings are conventionally called, and the angular contact is generally 15 degrees, 25 degrees, 45 degrees and so on.

Self-aligning ball bearing

A self-aligning ball bearing is a bearing equipped with spherical balls between the inner ring of two raceways and the outer ring whose raceway is spherical. The curvature center of the outer ring raceway surface is consistent with the bearing center, so it has the same centering function as the self-aligning ball bearing. When the shaft or housing is deflected, it can be adjusted automatically without increasing the bearing burden. Spherical roller bearings can bear radial load and axial load in two directions. Self-aligning ball bearings have large radial load capacity and are suitable for heavy loads and shock loads. Bearings whose inner diameter is a tapered bore can be directly installed. Or use an adapter sleeve or a disassembly tube to install it on the cylindrical shaft. The cage is made of steel stamping cage and polyamide forming. Self-aligning ball bearings are suitable for bearing heavy loads and impact loads, precision instruments, low-noise motors, automobiles, motorcycles, metallurgy, rolling mills, mining, petroleum, papermaking, cement, and pressing Sugar industries and general machinery, etc.
