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: contact lip seal on both sides made of rubber (2RS) for high sealing effect
- If you need this bearing in RS design with only one seal and one open side, you can simply remove one of the two seals: to the instructions
- 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)
