GQZ 7008SCT Single‑Row Angular Contact Ball Bearing 40×68×15mm 15° Contact Angle Precision Spindle Bearing

The 7008SCT open‑type single‑row angular contact ball bearing adopts 15‑degree contact angle with SCT precision tolerance configuration. It can bear combined radial load and single‑direction axial thrust load, features low run‑out and excellent high‑speed performance. Open‑type structure supports external lubrication and DB / DF duplex pairing for precision spindle equipment.

It is widely used for high‑speed machine tool spindles, high‑frequency motors and automated rotary positioning units.
