This product is widely used in various fields of precision miniature equipment and instruments. Key applicable industries include: micro motors (e.g., drone motors, model motors), office automation equipment (e.g., printers, scanners), precision instruments and meters, medical devices (e.g., dental handpieces, small pumps), robotic joints, optical equipment, audio equipment, and high-precision industrial control systems.
Product Structure
The S683 ZZ is a standard miniature deep groove ball bearing with dimensions conforming to the metric series. Key parameters are: 3mm bore diameter, 7mm outer diameter, and 3mm width. Structurally, it consists of an inner ring, outer ring, and precision steel balls made of quality chrome steel. It is equipped with two pressed steel shields (denoted by ZZ suffix) for dual-side sealing. The cage, typically made of steel or nylon, ensures even ball distribution and stable operation.
Key Performance Features of S683 ZZ
The main performance features of this bearing include: 1. Low Friction & High Speed: Precision raceway grinding and smooth steel balls ensure very low friction torque, suitable for high-speed applications. 2. Dust Protection: Dual metal shields (ZZ) effectively prevent dust and fine particles from entering while retaining the internal grease, extending service life. 3. Smooth & Quiet Operation: High manufacturing precision ensures low noise and vibration during operation. 4. Good Radial Load Capacity: The deep groove design efficiently handles radial loads. 5. Ready-to-Use: Pre-lubricated with grease, maintenance-free, and easy to install.
Main Application Scenarios
In specific application scenarios, the S683 ZZ bearing is often used as the core supporting component in micro transmission systems. Examples include: supporting the rotor shaft in miniature DC motors for high-speed rotation; mounted at both ends of paper feed roller shafts in printers or scanners for smooth paper feeding; embedded in small gearboxes to reduce gear transmission friction; serving as the rotational pivot for pointers or encoders in precision measuring instruments; and used in applications with strict size and speed requirements such as drone propeller motors and computer cooling fans.
Technical Specifications & Requirements
Material: Rings and balls are typically made of GCr15 or similar high-carbon chrome bearing steel, heat-treated to a hardness of HRC 58-62.
Precision Grade: Generally conforms to ABEC1 or ABEC3 (ISO P0 or P6 class) precision standards, suitable for most common precision applications.
Clearance: Usually supplied with standard CN (Normal) group radial internal clearance. Other clearance groups are available upon request.
Lubrication: Pre-lubricated with quality lithium-based or synthetic grease. Lubricant can be customized for special temperature or speed requirements.
Operating Temperature: With standard grease, the general operating temperature range is -30°C to +120°C.
Load & Speed: Specific dynamic load ratings and limiting speeds refer to manufacturer's catalogs. Under good conditions, its limiting speed can reach tens of thousands of RPM.
Installation Requirements: Mechanical press-fitting or thermal mounting is recommended. Ensure proper tolerance fit between shaft and housing (typically shaft j5/k5, housing H6/H7). Avoid direct hammering to prevent bearing deformation.
