S686zz Bearing Product Overview & Core Advantages
The S686zz is a metric single row deep groove ball bearing engineered for precision and reliability in compact applications. Constructed entirely from stainless steel (rings, balls, and cage), it offers excellent corrosion resistance. Its shielded (ZZ) design provides effective protection against contaminant ingress while retaining lubrication. This bearing is optimized to handle primarily radial loads and is characterized by its low friction, smooth operation, and long service life, making it a robust solution for high-speed, precision-driven equipment.
S686zz Bearing Model Code Explained, Specifications & Naming Convention
| Suffix | Technical Meaning |
|---|---|
| S | Stainless Steel construction for enhanced corrosion resistance. |
| 68 | Standard boundary dimension series for miniature bearings. |
| zz | A shield on both sides. This non-contact seal protects against contaminants while minimizing friction, contributing to the high limiting speed. |
S686zz Bearing Structural Features & Performance Benefits
- High Precision & Smooth Operation: Manufactured to ABEC1 tolerance class with an MC3 radial internal clearance (0.002mm to 0.013mm), ensuring consistent performance and low vibration.
- Corrosion Resistance: The all-stainless steel construction, including the 300 series shield, makes the bearing suitable for harsh environments and washdown applications.
- High-Speed Capability: The optimized stainless steel cage and low-friction shielded design enable a high limiting speed of 36,000 rpm.
- Robust Load Capacity: With a dynamic load rating of 186 lbf and a static load rating of 72 lbf, it provides reliable performance under significant radial loads.
- Compact and Lightweight: With dimensions of 6x13x5 mm and a weight of only 2.68 grams, it is ideal for space-constrained and weight-sensitive designs.
S686zz Bearing Typical Application Areas
This miniature deep groove ball bearing is widely used in applications requiring small size, precision, and corrosion resistance. Key industries and equipment include:
- Precision Instruments: Optical encoders, measuring devices, and laboratory equipment.
- Small Motors and Drives: Stepper motors, servo motors, and miniature DC motors.
- Office Automation: Printers, scanners, and copiers.
- Medical Devices: Small pumps, dental handpieces, and diagnostic equipment.
- Robotics and Automation: Small joints, guides, and actuators.
