Self-aligning ball bearings

While VIIPLUS is recognized as the supplier in Self-aligning ball bearings manufacturing equipment, our Self-aligning ball bearings product range includes equipment for a wide variety of customers.

Self-aligning ball bearings have two rows of balls, a common sphered raceway in the outer ring and two deep uninterrupted raceway grooves in the inner ring. They are available open or sealed. The bearings are insensitive to angular misalignment of the shaft relative to the housing , which can be caused, for example, by shaft deflection.

Self-Aligning Double Row Ball Bearings are designed to work in applications where severe misalignment exists whether from mounting or shaft deflection. The concave raceway of the outer ring in combination with two rows of balls operate over a wide range of contact angles. Furthermore it aligns itself correctly with the shaft and assembly without causing undue stress on the rest of the bearing assembly.

Standard Self-Aligning Double Row Ball Bearings are produced with straight bores; however, tapered bores are available upon request. Noteworthy is that the self-aligning ball bearing has the lowest friction of all rolling bearings, which enables it to run cooler even at high speeds. Furthermore, the design allows for easy mounting and dismounting.

Self-Aligning Double Row Ball Bearings come in three numeric series which represent the maximum specified degree of misalignment and loads:

1200 Series – Can be misaligned 2.5°
1300 Series – Can be misaligned 3.0°
2200 Series – Can be misaligned 2.5° - wider than the 1200 Series
11200 Series – with wider inner ring

Features and benefits

• Accommodate static and dynamic misalignment
  The bearings are self-aligning like spherical roller bearings or CARB bearings.
• Excellent high-speed performance
  Self-aligning ball bearings generate less friction than any other type of rolling bearing, which enables them to run cooler even at high speeds.
• Minimum maintenance
  Because of low heat generation, the bearing temperature is lower, leading to extended bearing life and maintenance intervals.
• Low friction
  Very loose conformity between balls and outer ring keeps friction and frictional heat at low levels.
• Excellent light load performance
  Self-aligning ball bearings have low minimum load requirements.
• Low noise
  Self-aligning ball bearings can reduce noise and vibration levels, for example, in fans.
