6904 Thin Section Ball Bearing – Maximum Performance in Minimal Space

With its ultra-thin 20x37x9mm profile, the 6904 thin section deep groove ball bearing belongs to the 69 series—a family of extra-thin metric ball bearings designed for applications where radial space is critically limited.This constant-thin geometry allows designers to incorporate larger shaft diameters without proportionally increasing bearing envelope size—a decisive advantage in weight-sensitive and space-constrained equipment.

Características clave:

• Durable Construction Material
  El 6904 bearing is manufactured from high-carbon chrome steel, Templado completamente a una dureza óptima para resistencia a la fatiga por contacto rodante.. This material delivers excellent wear resistance and dimensional stability, ensuring consistent performance across repeated load cycles and extended service intervals.

• Bajo nivel de ruido, Baja vibración
  The precise raceway finish and ball quality of the 6904 result in very low noise and vibration characteristics. This makes the bearing particularly suitable for noise-sensitive applications such as medical equipment, office machinery, and residential HVAC systems.

• Save Design Space
  The 6904’s defining advantage is its exceptionally slim cross-section. With an outer diameter only 17mm larger than its bore and a width of just 9mm, this bearing fits where standard bearings simply cannot. For engineers working on miniaturization or weight reduction, the 6904 transforms design possibilities. Whether developing slimline medical devices, compact robotic joints, or lightweight drone components, this bearing provides reliable rolling support without compromising design goals.

• Ligero, 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.
