Deep Groove Ball Bearings of the series HC-69 (Hybrid)

Special feature of this series
Main dimensions according to DIN 625-1. Hybrid thin section bearings of the HC-69 series are equipped with low-wear, current insulating ceramic balls withstanding extremely high speeds. They have considerably smaller dimensions than deep groove ball bearings of the HC-60, HC-62, HC-63 and HC-64 series with their thincross section at the same inside diameter. In comparison to their inside diameter they have a small outside diameter - and furthermore - they are relatively narrow. Relatively high shaft- and axis diameters can thereby be installed at an also extremely confined installation space. They are light and are suitable for comparatively high speeds. They are available with rings made of stainless steel or rolling bearing steel.
Seals
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
