Features
Precision Thin Section Bearing 6704 (20x27x4mm) – High-Performance Solution for Smooth Motion
Ultra-thin 4mm cross-section design maximizes space efficiency without compromising load capacity, ideal for compact assemblies like bicycles, drones, and small machinery. Premium 52100 chrome steel construction with precision grinding ensures low friction, high rigidity, and extended service life under dynamic/static loads. Dual shielded (6704ZZ) or rubber-sealed (6704 2RS) options provide reliable dust/moisture protection, suitable for outdoor or high-contaminant environments. Deep groove raceway geometry handles radial and axial loads simultaneously, perfect for bike hubs, robotics, and conveyor systems. Mirror-polished surfaces and ABEC-1 tolerances guarantee silent operation at up to 12,000 RPM, reducing vibration in high-speed applications. Interchangeable with 61704 series bearings – globally standardized dimensions for easy replacement across industrial/consumer equipment. Bulk pricing available – wholesale quantities shipped globally with OEM-grade packaging to ensure transit safety.
