Bearing manufacturer told you deep groove ball bearing and self-aligning bearing have what differentiation

Bearing manufacturer told you deep groove ball bearing and self-aligning bearing what is the difference between source: bearing | last updated: - 2020 09 - 03 deep groove ball bearing and self-aligning bearing are what is the difference between two kinds of bearing is there a difference in structure and using occasions. Self-aligning bearing outer ring raceway on bearing center as the center of the sphere, so when the inner ring and outer ring even stagger Angle, still on the sphere rolling roller, roller and the bearing center distance will not change, so will not stuck or wear and tear, so is self-aligning bearing. Self-aligning bearing can be applied on both ends of the long axis, and is suitable for the protection and insufficient bending rigidity of shaft. And deep groove ball bearing outer ring rolling is not spherical, so can't automatically self-aligning, so he is suitable for short shaft stiffness is bigger. Deep groove ball bearing has simple structure, easy to use, suitable for high speed, application is very wide, can bear radial force also can absorb a certain amount of axial force. Self-aligning bearing capacity is small, mainly bear radial load, has the very good so can automatically compensate for shaft deflection and alignment errors caused by casing deformation, suitable for bearing seat holes can't strictly to the widget. Three main characteristic: the characteristics of deep groove ball bearing one: it consists of an outer ring, an inner ring, a set of steel ball and a set of cage. Characteristics of the two: it mainly under pure radial load, also can take to load. When subjected to pure radial load, the contact Angle is zero. When it has large radial game, namely with angular contact bearing performance, can withstand a large axial load. Deep groove ball bearing small friction coefficient, high limit speed, so when the axial load at high speed, it is more superiority than thrust bearing. But because of its self-aligning properties limited, so the bearing installed higher concentricity, otherwise it will affect the operation of the balance, increase the bearing stress, so as to shorten the working life. Features three: deep groove ball bearing structure is simple, compared to other easy to achieve a high precision, so can into mass production. In addition to the conventional model, it also has all kinds of structure forms, such as dust cover deep groove ball bearings, deep groove ball bearings with rubber ring and a locking groove deep groove ball bearings, and so on.
