Self Aligning Ball Bearing

TFL supplies all types of self aligning ball bearing, types: linear self-aligning bearings, flange self-aligning bearings, thrust self-aligning bearings; optional brands include: SKF, NTN, NSK, KOYO, TIMKEN, etc., or according to customers The application of customized non-standard size self-aligning bearings.

What Are Self Aligning Ball Bearings?

A self-aligning ball bearing is equipped with spherical balls between the inner ring of two raceways and the outer ring, whose raceways are spherical.

The curvature centre of the outer ring raceway surface is consistent with the bearing centre, so it has the same centring function as the self-aligning ball bearing. When the shaft or housing is deflected, it can be adjusted automatically without increasing the bearing burden.

What Are Self Aligning Ball Bearing Used for?

Features of self aligning ball bearings:

  • When the shaft and housing are deflected, it can be adjusted automatically and has self-alignment without increasing the burden on the bearing.
  • The self-aligning ball bearing has a large radial load capacity. It is mainly suitable for the phenomenon of heavy load and shock load.
  • Good shock resistance and long service life.
  • Better sealing function
  • The concentricity error caused by machining, installation, and shaft deformation can be compensated.

These bearings have the function of self-aligning. The so-called alignment mainly refers to the automatic adjustment between the roller and the spherical track in shaft misalignment. To achieve a process of maintaining regular operation under a certain misalignment angle, Japanese bearing brands also adjust the alignment Ball bearings are called self-aligning bearings.

The self-aligning (automatic centring) function of self-aligning bearings is mainly used for adaptability to vibration conditions. Because of its automatic centring process, when the machine and the shaft vibrate, the roller and the raceway can be Automatically adapt to changes in angle, thereby reducing damage to shafts and bearings. At the same time, during installation, the centring requirements are also lower. Absolute centring is not required (that is, the radial section of the bearing and the shaft are at a 90-degree right angle close to complete), which is convenient for installation.

Application fields: Self aligning ball bearings are mainly suitable for those bearings that can cause considerable shaft deflection or misalignment and are used in pleasing appearance, low-noise motors, transmission shafts of automobiles, motorcycles, woodworking machinery, textile machinery, and mines. Machinery, electromechanical equipment, plastic machinery, work equipment, medical equipment, fitness, sports equipment, general machinery, etc.

In the final analysis, the most significant advantage of self-aligning bearings is their self-aligning function, which adapts well to misalignment conditions.
