6002Z Single Row Deep Groove Ball Bearing Single Side Z Metal Dust Shield 15x32x9mm Mini Fan Small Motor Transmission Equipment

The 7201T2DB is factory pre-ground matched DB back-to-back duplex angular contact ball bearing. T2 stands for glass fiber reinforced nylon high-speed cage, standard 20° contact angle open design. DB back-to-back pairing widens the force action span, delivers outstanding bidirectional axial rigidity and strong anti-tilting capacity, specially developed for miniature high-speed spindles, precision testing instruments and small automation rotary shafts requiring high positioning stability and low heat generation.

• T2 glass fiber nylon cage features lightweight, low rotation inertia, anti-deformation and stable lubrication under continuous ultra-high-speed running
• DB back-to-back duplex layout separates load action lines, greatly improves anti-overturn performance to restrain shaft deflection and tilting
• Integrated factory pre-matching eliminates manual pairing deviation, uniform preload force and ultra-low rotational runout
• 20° medium contact angle balances high limiting speed and reliable bidirectional radial & axial composite load bearing capacity
• Ultra-pre superfinished raceway and steel balls suppress vibration, noise and thermal deformation for precision micro machining equipment
• Multiple customizable options: P4/P5 high precision grade, ceramic hybrid steel balls, DF face-to-face pairing, double-sided dust-proof seal
• Standard metric miniature dimension, fully interchangeable with mainstream small high-speed spindle replacement bearing sets
