7006UCD2 D2 DF Duplex Angular Contact Bearing 30×55×26mm Nylon Cage High Speed Spindle Bearing GQZ

• 7006UCD2 is a factory pre-matched D2 DF face-to-face duplex angular contact ball bearing set, assembled by two 7006UC single bearings with 15° small contact angle, overall dimension 30×55×26mm. It adopts lightweight UC glass fiber reinforced polyamide ball-guided cage to cut friction and temperature rise during continuous ultra-high-speed rotation. D2 DF face-to-face layout features convergent load lines, outstanding capacity to compensate slight shaft misalignment while bearing combined radial load and bidirectional axial load simultaneously. Open structure fits circulating oil lubrication to reach maximum limiting speed. All paired sets are pre-adjusted with uniform light preload without secondary shimming; superfinished raceways and steel balls deliver low-vibration quiet running, widely used for miniature high-precision high-speed rotary machinery.
