SF699zz Bearing Product Overview & Core Advantages
The 61900-2Z is a metric single row deep groove ball bearing designed for exceptional performance in compact spaces. Its shielded construction (2Z) provides effective contamination protection while maintaining low friction operation. Manufactured entirely from stainless steel components, this bearing offers excellent corrosion resistance and reliable operation across a temperature range of -30° to 110°C. With its flanged outer ring design, it provides simplified axial location during installation, making it ideal for applications requiring precise positioning and high rotational accuracy.

|---|---|---|
| 61900 | Deep groove ball bearing series with 9mm bore diameter | Standardized dimension series for interchangeability |
| 2Z | Double-sided steel shields | Effective contaminant exclusion while maintaining low torque |
SF699zz Bearing Structural Features & Performance Benefits
Deep Groove Geometry: The optimized raceway profile enables this single row bearing to handle significant radial loads while accommodating moderate axial loads in both directions, providing versatile load capacity in a compact package.
Full Stainless Steel Construction: All critical components including rings, balls, cage, and shields are manufactured from stainless steel, ensuring excellent corrosion resistance and making it suitable for harsh environments and washdown applications.
Flanged Design Advantage: The integrated flange (23mm OD, 1.5mm thickness) simplifies mounting and provides positive axial location, reducing installation time and improving positional accuracy in housing designs.
Precision Performance: Manufactured to ABEC1 tolerance class with controlled radial internal clearance (MC3 group), this bearing delivers consistent running accuracy and smooth operation essential for precision applications.
SF699zz Bearing Typical Application Areas
- Small precision motors and miniature gearboxes
- Medical devices and laboratory equipment requiring corrosion resistance
- Food processing machinery where washdown compatibility is essential
- Office automation equipment including printers and scanners
