682xzz Bearing Product Overview & Core Advantages
The 682xzz is a miniature deep groove ball bearing designed for applications demanding compact size and reliable performance. This metric single row bearing features a shielded design for contaminant protection and is optimized for radial load applications. Its small footprint, with a 2.5 mm bore and 6 mm outside diameter, makes it ideal for high-precision, space-constrained mechanisms. Manufactured from high-grade chrome steel with a stainless steel cage, it offers a robust solution for a wide operating temperature range and requires lubrication for optimal service life.
682xzz Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 68 | Series designation, indicating a very small cross-section and bore diameter. |
| 2 | Bore diameter code. Represents a 2.5 mm bore diameter. |
| ZZ | Signifies shielded on both sides. The shields, made from 300 Series Stainless Steel, protect against contamination while allowing for high-speed operation. |
682xzz Bearing Structural Features & Performance Benefits
- Compact & Lightweight Design: With a width of just 2.6 mm and a weight of only 0.35 g, this bearing is engineered for miniature assemblies without sacrificing performance.
- Robust Load Capacity: The deep groove raceway and construction from hardened chrome steel provide a radial dynamic load rating of 40 lbf and a static load rating of 13 lbf, ensuring reliable operation under stress.
- High-Speed Capability: The combination of a low-friction stainless steel cage, precision ABEC1 tolerances, and optimized MC3 radial internal clearance enables a limiting speed of 71,000 rpm.
- Enhanced Service Life: The non-contact shields (ZZ) help retain lubricant and exclude debris, extending bearing life. The standard lubrication requirement allows for the use of specialized greases to match specific application needs across a temperature range of -30°C to 110°C.
682xzz Bearing Typical Application Areas
This bearing is commonly specified in:
- Small Precision Motors: Including stepper motors and coreless motors.
- Medical and Dental Handpieces: Where small size, high speed, and reliability are critical.
- Office Automation Equipment: Such as printers, scanners, and small fans.
- Instrumentation and Gauges: For precise rotary movement in measuring devices.
- RC Models and Drones: In miniature gearboxes and rotor assemblies.
