High Precision Deep Groove Ball Bearings of the series SS638 (Stainless Steel)

Special feature of this series
Precision deep groove ball bearings of this 638 stainless steel thin section series are manufactured to tighter tolerances than regular deep groove ball bearings and are corrosion resistant. With their thin rectangular cross section, they have considerably smaller dimensions than deep groove ball bearings of the 60, 62, 63 and 64 series with the same inner diameter. As a result, they can be installed on relatively large shaft and axle diameters, even in very tight spaces. They have the same outside diameter as thin section bearings of the 68 series, but are wider. They are very light and suitable for comparatively very high 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
