MR62 2rs Bearing Product Overview & Core Advantages
The MR62 2RS is a high-performance miniature deep groove ball bearing designed for precision applications requiring reliable operation in compact spaces. This sealed bearing features a single-row design optimized for radial loads and offers excellent rotational accuracy. Its compact dimensions (2mm bore, 6mm OD) and lightweight construction (0.28g) make it ideal for applications where space and weight are critical constraints. Manufactured with chrome steel rings and balls, it delivers dependable performance and long service life.
MR62 2rs Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| MR62 | Indicates a miniature radial ball bearing series with a 2mm bore diameter and 6mm outside diameter. |
| 2RS | Denotes double rubber seals on both sides, providing effective protection against contamination and retention of lubricant. |
MR62 2rs Bearing Structural Features & Performance Benefits
- Robust Sealing: The double rubber seals (2RS) effectively shield the bearing interior from dust, moisture, and other contaminants, while also retaining lubricant for extended service intervals.
- Precision Engineering: Manufactured to ABEC1 tolerance class, ensuring consistent running accuracy and smooth operation, which is critical for high-speed applications up to 75,000 rpm.
- Optimized Internal Clearance: Features a MC3 radial internal clearance (0.002mm to 0.013mm), providing stable operation across a range of temperatures and fit conditions.
- Durable Construction: Utilizes chrome steel for rings and balls, coupled with a stainless steel cage, ensuring high strength, wear resistance, and corrosion protection.
- Reliable Load Capacity: With a dynamic load rating of 63 lbf and static load rating of 18 lbf, it handles significant radial loads for its size, ensuring longevity in demanding applications.
MR62 2rs Bearing Typical Application Areas
- Small Precision Motors: Ideal for use in miniature DC motors, stepper motors, and coreless motors found in drones, robotics, and medical devices.
- Office Automation Equipment: Commonly used in printers, scanners, and copiers for precise paper handling mechanisms.
- Instrumentation and Gauges: Suitable for sensitive measuring instruments and control devices requiring smooth, low-friction rotation.
- Consumer Electronics: Applied in small fans, cooling systems, and various rotating components within compact electronic products.
- Industrial Automation: Used in small actuators, encoders, and other precision components within automated systems.
