601xzz Bearing Product Overview & Core Advantages
The 601xzz is a miniature deep groove ball bearing designed for applications demanding compact dimensions and reliable performance. This metric single row bearing features shielded construction, offering effective protection against contamination while maintaining low friction. Engineered with chrome steel rings and balls, it provides excellent durability and consistent operation. Its primary advantages include a compact 1.5 mm bore, suitability for high-speed operation up to 75,000 rpm, and compliance with ABEC1 precision tolerances, making it ideal for precision instruments and small mechanical assemblies where space and reliability are critical.
601xzz Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 601 | Basic bearing series, indicating a miniature deep groove design with a 1.5 mm bore and 6 mm outside diameter. |
| zz | Denotes shielded construction on both sides. The shields, made from 300 Series Stainless Steel, protect the internal components from dust and debris while allowing for high-speed operation. |
601xzz Bearing Structural Features & Performance Benefits
- High-Speed Capability: The combination of a stainless steel cage, six precision chrome steel balls (1.2 mm diameter), and optimized internal geometry enables a limiting speed of 75,000 rpm, making it a capable high-speed bearing for miniature applications.
- Radial Load Capacity: As a single row deep groove ball bearing, it is primarily designed to support radial loads effectively, with a dynamic load rating of 63 lbf and a static load rating of 18 lbf.
- Contamination Protection: The non-contact shields (zz) help retain lubricant and exclude large particulate contaminants, enhancing bearing life and reliability in challenging environments.
- Precision & Stability: Manufactured to ABEC1 tolerance class and featuring a controlled MC3 radial internal clearance (0.002mm to 0.013mm), this bearing ensures smooth, low-vibration operation essential for precision equipment.
601xzz Bearing Typical Application Areas
- Small DC Motors & Stepper Motors
