High Precision Miniature Ball Bearings of the series MR
- High precision miniature ball bearings of the series MR are comparatively small and have an inner diameter from 2 to 8 millimetre. Therefore, they are suitable for 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.
- A standard internal clearance (CN) is suitable for the operation of the bearing in case of ordinary temperatures and for customary fits. An increased internal clearance (C3) is recommendable in case of high temperature gradients between the rings or in case of fixing the bearing through a press fit. | more
- 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
