602 2rs Bearing Product Overview & Core Advantages
The 602 2RS is a metric miniature ball bearing designed for compact applications requiring reliable performance. As a single row deep groove ball bearing, it excels at handling radial loads and is sealed on both sides (2RS) with nitrile rubber contact seals for robust contamination protection. Its small bore diameter of 2 mm and lightweight 0.6 g construction make it ideal for space-constrained, high-speed applications up to 60,000 rpm. Manufactured to ABEC1 precision tolerances, this bearing offers a cost-effective solution for applications demanding consistent operation and long service life.
602 2rs Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning | Benefit |
|---|---|---|
| 602 | Basic bearing series; denotes a metric, single row deep groove ball bearing with a 2mm bore. | Standardized dimensions for easy integration and replacement. |
| 2RS | Contact seals on both sides made of Nitrile Rubber (NBR). | Superior protection against dust, moisture, and debris, retaining lubricant effectively for maintenance-free operation. |
602 2rs Bearing Structural Features & Performance Benefits
- Deep Groove Raceway & Single Row Design: Optimized for high radial dynamic load capacity (74 lbf), ensuring stable performance under primary radial forces.
- Double-Sided Sealing (2RS): Nitrile rubber contact seals provide excellent exclusion of contaminants while retaining grease, making the bearing suitable for environments where re-lubrication is impractical.
- High-Speed Capability: The combination of a stainless steel cage, seven precision chrome steel balls, and optimized internal geometry enables reliable operation at limiting speeds of 60,000 rpm.
- Precision & Consistency: Manufactured to ABEC1 tolerance class and MC3 radial internal clearance (0.002mm to 0.013mm), providing smooth and quiet running for precision mechanisms.
- Material Integrity: Rings and balls made from chrome steel offer high hardness and wear resistance, while the stainless steel cage provides corrosion resistance and durability.
602 2rs Bearing Typical Application Areas
- Small Electric Motors: Spindle motors in drones, small fans, and precision DC motors.
- Precision Instruments & Medical Devices: Optical encoders, dental handpieces, and laboratory equipment.
- Office Automation & IT Equipment: Hard disk drives, printers, and scanner mechanisms.
- Robotics & RC Models: Joints, gearboxes, and small drive wheels requiring compact, high-speed bearings.
- Pumps & Small Gearboxes: Miniature fluid pumps and low-torque transmission systems.
