Product Overview
High-Precision 605ZZ / 605Z Miniature Deep Groove Ball Bearing
The 605ZZ (605Z) 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 5.0mm (0.2″), an outer diameter of 14.0mm (0.55″), and a width of 5.0mm (0.2″), the 605ZZ is a widely utilized component across micro-motion control systems, 3D printing equipment, and RC mechanics.
High-Grade Chrome Steel & Dust Shielded Protection
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. Equipped with dual non-contact stamped metal shields (ZZ designation), the bearing retains internal factory lubrication while preventing ambient dust, debris, and particulates from entering the raceway.
Optimized for High RPM & Silent Running
Featuring precision-honed raceway grooves and a balanced steel ribbon cage, the 605ZZ maintains low rotational resistance and quiet running characteristics at speeds up to 38,000 RPM. Its tight dimensional tolerances guarantee smooth radial load support with minimal axial play.
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.
- Flanged Ring Design: Flanged outer ring model (F605ZZ) available for simplified housing mounting and axial location.
- Lubrication Customization: High-temperature grease, low-torque synthetic oil, or dry-film lubricants available upon order specification.
- Precision Grading: Available in ABEC-1, ABEC-3, ABEC-5, and ABEC-7 tolerance classes.
