602 Bearing Product Overview & Core Advantages
The 602 metric ball bearing is a fundamental single row deep groove ball bearing designed for high-performance applications requiring reliable radial load support. Characterized by its compact dimensions (2mm bore, 7mm OD) and lightweight construction (0.5g), this open-type bearing offers versatile mounting options and efficient operation. Manufactured from chrome steel with an ABEC1 tolerance class, it provides a cost-effective solution for applications demanding consistent performance and high rotational speeds up to 60,000 rpm.
602 Bearing Model Code Explained, Specifications & Naming Convention
| Code Element | Technical Significance |
|---|---|
| 60 | Series designation indicating a deep groove ball bearing with a specific cross-section. |
| 2 | Bore diameter code, corresponding to a 2 mm bore. |
| Open (No Seal Suffix) | No integral seals or shields, allowing for high-speed operation and custom lubrication schemes. Requires external sealing in contaminated environments. |
602 Bearing Structural Features & Performance Benefits
- Optimized Deep Groove Raceway: The deep, continuous raceways on both rings enable smooth operation and efficient handling of radial loads, as evidenced by its 74 lbf dynamic load rating.
- High-Speed Stainless Steel Cage: The stainless steel cage precisely guides the seven balls, ensuring stability and low friction at the limiting speed of 60,000 rpm.
- Precision Chrome Steel Construction: Both rings and balls are made from chrome steel, providing high hardness, wear resistance, and durability for long service life.
- Controlled Internal Clearance: The specified MC3 radial internal clearance (0.002mm to 0.013mm) ensures optimal performance by accommodating thermal expansion in various operating conditions.
602 Bearing Typical Application Areas
This miniature 602 ball bearing is ideally suited for compact, high-speed mechanisms, including:
- Small Precision Motors: Spindle support in miniature DC motors and stepper motors.
- Medical Devices & Instrumentation: Critical components in dental handpieces, miniature pumps, and optical scanners.
- Office Automation Equipment: Guide rollers and drive mechanisms in printers, scanners, and copiers.
- Robotics & RC Models: Joints, gearboxes, and wheel hubs requiring lightweight and responsive bearings.
