Features
- double row design: significantly higher load capacity than comparable single row deep groove ball bearings; additionally, it can support tilting moments
- narrower than two comparable single row deep groove ball bearings side by side
- cage material: plastic; the low weight and the elasticity of the plastic have a positive effect on the sliding and emergency running properties as well as the shock resistance; suitable for quiet running
- light series with compact dimensions and low weight
- suitable for very high radial loads and light axial loads in both directions
- suitable for high running accuracy, quiet running and high speeds
- 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)
