Description

DNT Auto Parts Spindle Bearing Sealed Angular Contact Ball Bearing 70, 72, 718, 719 for Machine Tool Spindle, CNC Machine, Motor, Gas Turbine, Robot Industry

The DNT precision angular contact ball bearings for spindles, have four size series,718,719,70 and 72. With the same inner diameter, the outer diameters and the widths of 718,719,70 and 72 series increase in turn.

DNT precision angular contact ball bearing with 15 ° (C) and 25 ° (AC) contact angles. As for the angular contact ball bearings, the bigger the contact angle is, the greater the axial load capacity is, but the lower the limited speed of bearings becomes. Therefore ,the spindle, with high speed and small axial load ,should adopt the 15 ° angular contact ball bearings,whereas the 25 ° angular contact ball bearing should be adopted.

DNT precision angular contact ball bearings with high-speed angular contact bearings (standard series), super-speed angular contact ball bearings, high-speed sealed angular contact ball bearings and high-speed spindle bearings
