High Precision Miniature Ball Bearings of the Series R in inch sizes
- High precision miniature ball bearings of the series R with inch dimensions are comparatively small and have an inner diameter from 2.38 to 9.525 millimetre. Therefore, they are suitable for relatively thin shafts and axis as well as for appropriate small space requirements. In the ratio to its small size, miniature deep groove ball bearings can take up relatively high loads. High precision miniature ball bearings are manufactured to tighter tolerances and are characterized by increased running smoothness. They are therefore better suitable for high to extremely high rotational speeds.
- Rubber seals (RS/2RS) have the optimum sealing action with increased friction. Metal seals (Z/ZZ) are suitable for higher speeds, but they have a limited sealing action as they seal contactless. Open, seal-less bearings are suitable for extremely high speeds and - furthermore - they can be regreased more easily. However, they are more susceptible to soiling. | more
