Product Details
These bearings are designed to support ball screws that are utilized as actuators in high precision and high speed machines, offering significantly greater stiffness compared to conventional angular contact ball bearings due to their larger number of balls. Each bearing comes with a pre-set preload, eliminating the need for complicated adjustments and torque measurements. Flush ground bearings, identified by the suffix DU or U, are compatible for use in DB (back to back), DF (face to face), or DT (tandem) assembly configurations. It is important to note that when a single flush ground bearing with the suffix U is assembled in duplex and an axial load is applied to two or three rows, the load ratings must be increased by a factor of 1.62 or 2.16 respectively for dynamic load ratings, and multiplied by 2 or 3 respectively for axial limiting loads.
