Features
- self-aligning ball bearing with two rows of balls
- pivoting inner ring, misalignments and shaft deflections can be compensated
- suitable for high radial loads and light axial loads in both directions
- cage material: sheet steel, high load-bearing capacity and high strength; suitable for continuous high temperatures
- seal: open (without seal); for higher speeds than with sealed ball bearings and easy relubrication
- good fixed bearing property, but can also be used as a floating bearing, each in both directions
- manufacturers of bearings, such as FAG, KOYO, NSK, SKF, SNR, etc. assign different suffixes for their characteristics, for better orientation take note of the comparison table of bearings (see further information)
