682 Bearing Product Overview & Core Advantages
The 682 is a metric miniature deep groove ball bearing designed for high-precision applications requiring compact dimensions and reliable performance. As a single row radial bearing, it efficiently supports primarily radial loads. Its open design allows for versatile lubrication options, making it suitable for high-speed operation up to 85,000 rpm. Manufactured with chrome steel rings and balls and a stainless steel cage, this bearing offers excellent durability and consistent operation within a temperature range of -30°C to 110°C. It is an ideal component for applications demanding miniature bearing solutions with ABEC1 precision.
682 Bearing Model Code Explained, Specifications & Naming Convention
| Model Segment | Technical Meaning |
|---|---|
| 682 | Standard model number for a miniature deep groove ball bearing with a 2mm bore, 5mm OD, and 1.5mm width. |
| Open | The bearing has no integral seals or shields, allowing for custom lubrication and higher potential speeds. |
| MC3 | Specifies a greater than normal radial internal clearance (0.002mm to 0.013mm), suitable for applications with thermal expansion or where a looser fit is required. |
682 Bearing Structural Features & Performance Benefits
- High-Speed Capability: The combination of an open design and a lightweight stainless steel cage minimizes friction and allows for a high limiting speed of 85,000 rpm, making it an excellent high-speed bearing.
- Radial Load Capacity: The deep groove raceway and six precision chrome steel balls are engineered to handle the specified radial dynamic load rating of 32 lbf effectively.
- Precision & Stability: Manufactured to ABEC1 tolerance class with strict bore and outside diameter tolerances, ensuring smooth and precise rotation for sensitive applications.
- Durability & Corrosion Resistance: The stainless steel cage provides enhanced corrosion resistance and strength, contributing to the bearing's long service life.
- Flexible Lubrication: The open structure permits the use of specialized lubricants tailored to specific operational needs, such as extreme temperatures or high speeds.
682 Bearing Typical Application Areas
- Small Precision Motors: Ideal for spindle support in miniature DC motors and stepper motors.
- Medical Devices: Used in surgical hand tools, dental drills, and small pumps where compact size and reliability are critical.
- Office Automation Equipment: Suitable for components in printers, scanners, and small fans.
- Instrumentation and Gauges: Provides precise rotational support in various measuring devices and sensitive instruments.
- Robotics: Used in small joints, gearboxes, and actuators within compact robotic assemblies.
