Description
- THIN SECTION LARGE BORE FIT: Model: 6904ZZ (Globally recognized as 6904ZZ , 6904ZZ ). Exact Specifications: 20mm Inner Diameter (Bore) x37mm Outer Diameter (OD) x 9mm Width. Engineered with an ultra-thin wall profile specifically for space-constrained assemblies requiring a large 20mm shaft
- DOUBLE METAL SHIELDED FOR MAX RPM: Equipped with rigid dual metal shields (ZZ) on both sides. This specialized design effectively blocks dust and debris while maintaining exceptionally low friction, unlocking lightning-fast rotational speeds that rubber-sealed bearings cannot achieve
- THE HOLLOW-SHAFT ROBOTICS UPGRADE: The massive 20mm bore combined with a minimal 37mm OD makes it the ultimate choice for hollow-shaft motors, robotic arm joints, and camera gimbals where internal wiring or lasers must pass cleanly through the center of the mechanism
- LIGHTWEIGHT & HIGH EFFICIENCY: Forged from premium Chrome Steel (ABEC-3) and factory pre-lubricated with high-temperature machine grease. It delivers a buttery-smooth rotation and outstanding radial load distribution without adding unnecessary weight to your drones or precision instruments
- VERSATILE DRY-ENVIRONMENT USE: The perfect precision replacement bearing for high-speed, indoor mechanics. Highly recommended for custom 3D printers, optical equipment, indoor cycling trainers, and aerospace modeling.
