Product Overview
High-Precision 606 Open Type Miniature Deep Groove Ball Bearing
The 606 Miniature Ball Bearing is a standard metric single-row deep groove ball bearing engineered for high-precision, low-vibration, and high-speed rotary applications. Featuring a standard bore size of 6.0mm, an outer diameter of 17.0mm, and a width of 6.0mm, the open-type 606 configuration allows for direct oil mist or grease lubrication, making it ideal for high-RPM motor spindles and precision instruments.
High-Grade Chrome Steel & Low-Friction Design
Manufactured from high-carbon chromium bearing steel (GCr15 / AISI 52100), the inner and outer rings alongside the rolling elements undergo precision heat treatment to achieve superior hardness (HRC 60-65) and structural fatigue strength. Without the friction resistance of contact seals, the open 606 bearing delivers minimal starting torque and maximum energy efficiency for battery-powered or high-frequency drive systems.
Optimized for High RPM & Quiet Running
Featuring precision-honed raceway grooves and a balanced steel ribbon cage, the 606 maintains smooth rotational stability and quiet running characteristics at speeds up to 43,000 RPM. Its tight dimensional tolerances guarantee stable radial and axial load support under continuous operation.
Custom Manufacturing & Material Options
To meet specialized environmental requirements across OEM production lines, custom configurations are available upon request:
- Stainless Steel Options: Stainless steel (SUS440C / SUS304) construction for damp, corrosive, or food-grade applications.
- Shielded Variants: Metal shielded (606ZZ) or rubber sealed (606-2RS) models available for dust-heavy environments.
- Flanged Ring Design: Flanged outer ring model (F606) available for simplified housing mounting and axial location.
- Precision Grading: Available in ABEC-1, ABEC-3, ABEC-5, and ABEC-7 tolerance classes.
