MR62 Bearing Product Overview & Core Advantages
The MR62 is a metric single row deep groove ball bearing engineered for compact applications requiring reliable radial load support. Its miniature dimensions (2mm bore, 6mm OD, 2.5mm width) and lightweight construction (0.28g) make it ideal for space-constrained assemblies. Manufactured with chrome steel rings and balls and a stainless steel cage, it offers robust performance and consistent operation. With an ABEC1 tolerance class, it provides dependable precision for general industrial use.
MR62 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning | Significance |
|---|---|---|
| MR62 | Basic Bearing Designation | Indicates a metric, single row deep groove ball bearing with 2mm bore, 6mm OD. |
| Open (Seal Type) | No Seals/Shields | Allows for easy re-lubrication and is suitable for clean environments. |
| MC3 (Clearance) | Greater than Normal Radial Internal Clearance | Accommodates thermal expansion, suitable for applications with significant temperature variations. |
MR62 Bearing Structural Features & Performance Benefits
- High Load Capacity: The deep groove raceway and six 1.2mm chrome steel balls enable efficient handling of radial dynamic loads up to 63 lbf and static loads up to 18 lbf.
- Stainless Steel Cage: Provides excellent durability and corrosion resistance, ensuring stable ball guidance and reduced wear.
- Optimized for Speed: The robust cage design and MC3 clearance contribute to a limiting speed of 75,000 rpm, supporting high-speed operation.
- Precision Engineering: Manufactured to ABEC1 standards with tight dimensional tolerances (bore/OD: -0.008mm to 0) for consistent performance and easy installation.
- Versatile Temperature Range: Operates effectively from -30°C to 110°C, suitable for various environmental conditions.
MR62 Bearing Typical Application Areas
- Small Precision Motors: Ideal for spindle support in miniature DC motors and stepper motors.
- Medical Devices: Used in handheld surgical tools, dental handpieces, and diagnostic equipment pumps.
- Office Automation: Suitable for scanners, printers, and small cooling fans.
- Instrumentation & Robotics: Provides precise rotation in encoders, sensors, and small robotic joints.
- Consumer Electronics: Applied in drones, small cameras, and precision gearboxes.
