SMR62 Bearing Product Overview & Core Advantages
The SMR62 is a metric miniature ball bearing designed for applications requiring compact dimensions and reliable performance. As a single row deep groove ball bearing with an open design, it excels in handling radial loads efficiently. Manufactured entirely from stainless steel, it offers excellent corrosion resistance, making it suitable for various demanding environments. Its compact size of 2mm bore, 6mm outside diameter, and 2.5mm width makes it ideal for space-constrained, high-precision assemblies.
SMR62 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| SMR | Series designation for miniature metric bearings. |
| 62 | Specifies the bearing size: 2mm bore, 6mm OD, 2.5mm width. |
| Open (Implied) | No seals or shields, allowing for higher speeds and custom lubrication. Lubrication is required. |
| ABEC1 | Standard precision tolerance class, suitable for a wide range of general applications. |
| C3 Clearance | Greater than normal radial internal clearance (0.002mm to 0.013mm), accommodating thermal expansion in applications. |
SMR62 Bearing Structural Features & Performance Benefits
- Compact & Lightweight Design: With a total weight of just 0.28g, the SMR62 is engineered for applications where minimizing mass and size is critical, without sacrificing performance.
- Stainless Steel Construction: All components—rings, 1.2mm balls, and cage—are made from stainless steel, providing superior corrosion resistance and durability in harsh or wash-down environments.
- Optimized Load Capacity: The deep groove raceway and 6-ball configuration provide a dynamic load rating of 57 lbf and a static load rating of 16 lbf, ensuring reliable operation under radial loads.
- High-Speed Capability: The open design and stainless steel cage contribute to a high limiting speed of 67,500 rpm, making it suitable for high-speed miniature spindles and rotors.
- Standardized Precision: Manufactured to ABEC1 tolerances, this bearing offers consistent and reliable performance for general precision applications.
SMR62 Bearing Typical Application Areas
The SMR62 miniature bearing is ideally suited for:
- Small Precision Motors: Including stepper motors and coreless DC motors.
- Medical and Dental Devices: Such as handheld surgical tools and dental handpieces where compact size and corrosion resistance are vital.
- Office Automation Equipment: Including printers, scanners, and small fans.
- Instrumentation and Gauges: Providing smooth, low-friction rotation in precision measuring devices.
- RC Models and Drones: Used in miniature gearboxes and rotor assemblies.
