6814ZZCM NS7S5 Thin Wall Single Row Deep Groove Ball Bearing CM Motor Clearance NS7 Grease 70x90x10mm Servo Motor Equipment
The 6814ZZCM NS7S5 is ultra-thin wall single row deep groove ball bearing with double ZZ metal dust shields, CM motor controlled clearance and pre-filled NS7 low-temperature long-life grease, standard dimension 70×90×10mm. CM special clearance eliminates motor resonant vibration; double non-contact steel shields block fine dust without sacrificing high rotation speed. NS7 lubricant works stably from -40℃ to 130℃, maintains low friction and quiet running, widely used in servo motors, high-speed spindles, automation rotary shafts, fan equipment and precision light industrial transmission assemblies.
