Precision miniature ball bearings — Small bearings for highest demands
- Main dimensions according to DIN 625-1. Precision miniature deep groove ball bearings of this series are comparatively small and have an inner diameter of 2 to 9 millimeters. Therefore, they are suitable for relatively thin shafts and axis as well as for small space requirements. In the ratio to its small size, they can take up relatively high loads. They are suitable for high up to extremely high rotational speeds and are built to other tolerance classes than regular miniature deep groove ball bearings.
- Precision ball bearings are manufactured to other tolerance classes than regular ball bearings. This means that deviations in the dimensional and shape accuracy are lower than in bearings that are manufactured according to normal tolerances. They are therefore suitable for applications in which the highest precision in terms of dimensions and dimensional accuracy is required. The more precise production also has a positive effect on the running accuracy, the resulting friction and the noise development. The tolerance class P6 is more accurate than the normal tolerance. P5 is even more accurate than P6. The smaller the number behind the P, the higher the tolerance class.
- 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
Versions of precision miniature ball bearings
- Main dimensions according to DIN 625-1. Inside diameter below 10 mm. "All-round bearing". Versatile.
- For simplified locating bores in which the bearing is supposed to be axially fixed. Inside diameter below 10 mm.
Material description of precision miniature ball bearings
- are extremely economical, withstand extremely high load-ratings and are suitable for temperatures from circa -10°C up to +120°C, in case of rubber seals up to circa +100°C in the long run. The rolling bearing steel is wear-resistant, shock-resistant, conductive and magnetic.
- are hygienic, corrosion-resistant, lubricated with grease for the food industry, offer high load-ratings, magnetic and are admissible for a temperature range from circa -20°C up to +120°C, in case of rubber seals up to circa +100°C in the long run.
- are subject to a lesser wear and tear compared to bearings of similar size with steel balls. The ceramic balls are current insulating - optimally for use in engines and generators. Hybrid bearings are lighter than bearings with steel balls of the same size, withstand higher speeds, are magnetic and operate in a temperature range from circa -20°C up to +130°C, in case of rubber seals up to circa +100°C in the long run.
