Taking the NSK spindle bearing products in Japan as an example, precision spindle bearings include precision angular contact ball bearing 70 series, 719 series, 72 series, precision round The column roller bearing N10 series, NN30 series, TAC series of bearings for precision ball screw support.
Spindle bearing characteristics
High performance design.
High rigidity, Ball Number 600, contact angle, high stiffness.
Long life,EP steel with long life, high reliability, service life is 3 times that of ordinary bearing steel SUJ2.
Contact sealed bearing series,high reliability, high dust
Sealed bearing dustproof performance is good, not easy leakage of lubricating grease. And the use of light contact seal ring, bearing torque low, low fever.
