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.

3. Key Advantages
T2 glass fiber nylon cage features lightweight, low rotation inertia, anti-deformation and stable lubriion 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
Upgrade miniature equipment positioning accuracy, reduce thermal expansion deviation and extend continuous high-speed service cycle
