Explanation Of WSBC Self-aligning Ball Bearings

1. What is WSBC self-aligning ball bearing?

   Self-aligning ball bearings are bearings with spherical balls installed between the outer rings of the raceway spherical surfaces of the inner ring boxes of the two raceways. The outer diameter of the self-aligning functional bearing and the inner diameter of the bearing seat are spherical, and there is an active self-aligning function between the two, which can compensate for the misalignment of the axis due to the device error and the deformation of the bottom surface of the device.

2. Two structures of WSBC self-aligning ball bearings

   1) Cylindrical hole

   ①Because it has two rows of steel balls and a curved raceway in the outer ring, self-aligning ball bearings can be actively adjusted.

   ② It can accept the view point error between the shaft and the bearing housing, and is suitable for the simple presentation of shaft deflection and misalignment of the shaft center.

   ③ Friction is the lowest among all rolling bearings.

   ④ Even in the case of high speed, there is still only a small temperature rise.

   2) Conical hole

   ① Tapered bore self-aligning ball bearings have the characteristics of cylindrical bore self-aligning ball bearings.

   ②Because the clearance of the bearing can be fine-tuned, this type of bearing is mostly used in the parts of the double support shaft with large twists under load and the two support seat holes that cannot ensure strict concentricity.

   ③It is mainly used to accept radial load, and can also accept a few axial loads.

   ④ Normally, pure axial load cannot be accepted. The versatility of this type of bearing is second only to deep groove ball bearings.

   ⑤The limit speed is lower than the same standard deep groove ball bearing, but its load bearing capacity is higher than the deep groove ball bearing

3. Characteristics of self-aligning ball bearings

  1) The outer ring raceway is spherical and self-aligning.

  Even if the inner ring, steel ball and cage are skewed relative to the outer ring (but the relative inclination of the inner and outer rings must not exceed 3 degrees), they can rotate; therefore the bearings are self-aligning and are not affected by the shaft relative to the bearing housing Impact of misalignment

  2) It can bear larger radial load and also can bear certain axial load.

  The load can be large because the internal structure of the spherical ball bearing is the same as that of the 6200 and 6300 series deep groove ball bearings, so the IB spherical ball bearing with seat can not only accept radial load, but also can accept larger axial load. The noise of bearing operation is low.

  3) Long service life.

  Long-life spherical ball bearings with seats are generally used in harsh operating environments such as dirt, dust, humidity and high temperature. The smooth grease inside the bearing will degenerate in a short period of time. Therefore, it is necessary to inject grease on the spherical ball bearing with seat at the right moment and smooth from scratch, and replace the degraded smooth grease with fresh smooth grease. IB cast iron outer spherical ball bearings are equipped with grease nipples, which can be smooth from scratch, ensuring perfect function and long service life in any operating environment.

  4) The sealing function is better.

   Excellent sealing function The outer spherical ball bearing is equipped with a heat-resistant, oil-proof rubber seal ring and a steel dust cover combination seal on both sides. The dust cover is installed on the outer diameter of the inner ring of the bearing and rotates together with the inner ring, which can effectively prevent external foreign objects from entering the bearing and protect the bearing against external pressure. This combined seal consisting of a sealing ring and a dust cover can obstruct Mud, dust, and moisture enter the inside of the bearing, which together can block the smooth grease leakage inside the bearing. The bearing can also adhere to the perfect application field of operation function in a harsh working environment.

  5) Pure axial loads are usually not acceptable

   Suitable for bearings that can cause considerable shaft deflection or misalignment, such as fine appearance, low noise motors, automobiles, motorcycles, woodworking machinery, textile machinery transmission shafts, mining machinery, electromechanical equipment, plastic machinery , Work equipment, medical equipment, fitness and sports equipment and general machinery.
