The ZYS Spindle bearings represent a version of the single-row angular contact ball bearings, specifically designed for machine tool construction, but are also well suited for other applications with demanding precision and speed requirements. Compared to standard angular contact ball bearings, the spindle type units feature a different contact angle (15° and/or 25°), tolerance class and cage design. These units are available in several series including B719, B70, B72 and A73 with combination models, like HCB70 and HCB719 available per user request, and feature a standard universal design.
The model 760306TN1/P4DBB is a high-precision spindle bearing with a bore size of 30 mm, outside diameter of 72 mm and 19 mm width. This model is manufactured out of GCr15 material.
