68/0.6 Bearing Product Overview & Core Advantages
The 68/0.6 is a miniature single row deep groove ball bearing engineered for applications demanding extreme miniaturization and precision. Its defining characteristic is its exceptionally small bore diameter of 0.6 mm, making it a critical component in micro-mechanical systems. This bearing is designed to primarily handle radial loads efficiently within a compact footprint. Manufactured to ABEC1 precision class with MC3 clearance, it offers reliable performance and high rotational accuracy for its size, making it ideal for high-reliability, space-constrained applications.

| Code Segment | Technical Meaning |
|---|---|
| 68 | Standard series designation for this miniature bearing size. |
| 0.6 | Indicates the bore diameter in millimeters (0.6 mm). |
| (No Seal Suffix) | The bearing is Open, allowing for custom lubrication schemes and maximum speed capability, but requiring a clean operating environment. |
68/0.6 Bearing Structural Features & Performance Benefits
- High-Precision Miniature Design: With a bore diameter of 0.6 mm and an overall width of just 1 mm, this bearing provides a solution for the most compact assemblies without sacrificing performance.
- Optimized Load Capacity: The single row deep groove construction is efficiently designed to carry radial loads (13 lbf dynamic / 3 lbf static), making it suitable for small motors and instruments.
- High-Speed Capability: The combination of a stainless steel cage, five precision balls, and an open design contributes to a high limiting speed of 128,000 rpm.
- Precision and Stability: Manufactured to ABEC1 tolerance standards with a controlled MC3 radial internal clearance (0.002mm to 0.013mm), ensuring smooth and consistent operation.
- Material Integrity: Constructed from chrome steel rings and balls for durability and wear resistance, ensuring a long service life in demanding miniature applications.
68/0.6 Bearing Typical Application Areas
This miniature bearing is indispensable in sectors where size and precision are paramount. Key applications include:
- Miniature and Micro Motors (e.g., in medical devices, drones)
- Precision Instruments and Optical Encoders
- Small-Diameter Shafts in laboratory and testing equipment
- Office Automation Equipment (e.g., miniature printers, scanners)
- Small robotic joints and actuators
