SF694zz Bearing Product Overview & Core Advantages
The SF694zz is a metric miniature ball bearing designed for precision applications requiring compact dimensions and reliable performance. As a single row deep groove ball bearing, it is optimized to handle primarily radial loads efficiently. Constructed entirely from stainless steel, it offers excellent corrosion resistance. The inclusion of stainless steel shields (ZZ) provides robust protection against contaminant ingress, enhancing operational life in demanding environments. Its compact design, with a 4 mm bore and 11 mm outside diameter, makes it an ideal solution for applications where space is at a premium without compromising on load capacity or durability.
SF694zz Bearing Model Code Explained, Specifications & Naming Convention
| Suffix Code | Technical Meaning | Advantage |
|---|---|---|
| SF | Flanged Outer Ring | Simplifies mounting and positioning, providing axial location. |
| 69 | Miniature / Extra Small Bearing Series | Indicates a compact, lightweight design for miniature applications. |
| 4 | Bore Diameter Code (4 mm) | Specifies the precise internal diameter for shaft fitting. |
| zz | Non-Contact Shields on Both Sides | Offers excellent protection from dust and debris with minimal impact on limiting speed. |
SF694zz Bearing Structural Features & Performance Benefits
- Deep Groove Raceway & Single Row Design: The geometry of the raceway is optimized for handling radial loads, ensuring smooth rotation and low running torque.
- Full Complement Stainless Steel Construction: The rings, balls, and cage are all manufactured from stainless steel, providing superior corrosion resistance and making the bearing suitable for washdown environments or applications exposed to mild chemicals and moisture.
- Flanged Outer Ring: The integral flange (12.5 mm diameter) allows for easy and secure axial location within a housing, simplifying assembly and reducing the need for complex housing designs.
- Shielded Configuration: The non-contact ZZ shields are a key feature for contamination protection. They help retain lubrication and exclude particulate contaminants, significantly extending service life without the added friction of contact seals.
- ABEC1 Precision: Manufactured to ABEC1 tolerance class, this bearing provides a reliable balance of precision and cost-effectiveness for a wide range of industrial applications.
SF694zz Bearing Typical Application Areas
This bearing is engineered for compact, high-speed mechanisms across various industries. Common applications include:
- Small Precision Motors: Used in stepper motors, servo motors, and miniature DC motors.
- Office Automation Equipment: Ideal for printers, scanners, and copiers.
- Medical Devices: Suitable for handheld surgical tools, dental handpieces, and diagnostic equipment due to its stainless steel construction.
- Robotics and Automation: Found in small robotic joints, actuators, and conveyor system guides.
- Instrumentation and Control Systems: Used in encoders, gauges, and other precision measurement devices.
