Set-contained bearing

Its outer diameter for sphere, the bearing surface concave spherical inside the corresponding play self-aligning role

The spherical bearing detailed introduction:

The spherical ball bearing is actually deep groove ball bearing of a kind of form, characteristic is its outer diameter for spherical surface, can match the concave spherical bearing corresponding into play the role of spherical inside.

Although it's basic properties and deep groove ball bearing should be similar, but because the bearing mostly application of rough machinery, installation location is not very precise, shaft and seat hole axis to neutral difference, or axial length and deflection under the condition of the big etc, and bearing itself precision isn't high enough, some structure is coarser, therefore performance of actual performance comparison identical norms of deep groove ball bearings to play on a discount. For example: take top of silk ball bearings are used in the sphere of poor deflection big stiffness, the general shaft bearings with seals at both closely, can prevent sewage invaded, factory have reload right amount of lubricant, before installation, do not need to clean, do not need to add lubricant, bearing inner ring bulgy serve the top silk screw fastening on the axle. Allow the axial load must not exceed 20% of the rated dynamic load.

 With eccentric sets of the spherical ball bearings and covered the spherical bearing performance filaments of basic and same, just top silk does not included circle, but rather on the eccentric sets. The spherical ball bearings taper hole for belt of inner hole taper hole taper preached, can be directly mounted on tapered axis, or with tight set bushing installed in shaftless shoulder axis and can fine-tune bearing clearance.

The spherical bearing priority applies to request equipment and parts of simple situations, such as used for agricultural machinery, transport system or construction machinery.

Mainly used to inherit in radial direction load primarily radial and axial union load, should not be commonly alone bear axial load, these bearings can separately installs inner ring (with whole group roller and keep device) and outer ring. The bearing don't allow shaft relative shells tilt, in radial direction load appointment will generate additional axial force. The bearing axial clearance size, on the bearing can normal working relationship is very big, when axial clearance after hours, temperature is higher; Axial clearance is bigger, bearing damage easily. Therefore, in installation and operation to pay special attention to the bearing axial clearance may, when necessary, preloaded mounting, and to increase the bearing rigidity.
