Features
- angular ball bearing with one row of balls
- suitable for high radial loads and axial loads in one direction
- it has also an axial load carrying capacity on both sides in the X- or O-arrangement in pairs
- suitable for high running accuracy, quiet running and high speeds
- 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
- seal: open (without seal); for higher speeds than with sealed ball bearings and easy relubrication
- A pictorial representation of the correct installation direction can be found here: for representation
- good fixed bearing property in the X- or O-arrangement in pairs
- 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)
