SMF62 2rs Bearing Product Overview & Core Advantages
The SMF62 2RS is a compact, single row deep groove ball bearing designed for applications demanding high precision and reliability in a minimal space. Engineered with stainless steel rings and balls, it offers excellent corrosion resistance. A key feature is its sealed design (2RS), which effectively retains lubricant and excludes contaminants, making it suitable for environments where maintenance access is difficult. Its ability to handle primarily radial loads at high rotational speeds makes it an ideal choice for compact, high-performance mechanisms.
SMF62 2rs Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| SMF62 | Indicates the bearing series and size. A compact, flanged metric bearing with a 2mm bore, 6mm outside diameter, and 2.5mm width. |
| 2RS | Signifies that the bearing is fitted with contact rubber seals on both sides. This provides superior protection against contamination and effective grease retention. |
SMF62 2rs Bearing Structural Features & Performance Benefits
- Compact & Flanged Design: The integral flange on the outer ring simplifies mounting and positioning within a housing, saving space and assembly time.
- High-Speed Capability: The stainless steel cage and optimized internal geometry contribute to a high limiting speed of 67,500 rpm, enabling use in demanding, high-RPM applications.
- Robust Sealing: The Nitrile rubber (NBR) seals (2RS) provide excellent protection against dust, moisture, and other contaminants, significantly extending bearing service life and reducing the need for maintenance.
- Corrosion Resistance: Constructed entirely from stainless steel, this bearing is ideal for applications exposed to moisture, chemicals, or wash-down environments.
- Precision Performance: Manufactured to ABEC1 tolerance class, it ensures smooth and quiet operation, which is critical for precision instruments.
SMF62 2rs Bearing Typical Application Areas
This miniature deep groove ball bearing is ideally suited for:
- Small Precision Motors (e.g., in drones, medical devices)
- Office Automation Equipment (e.g., printers, scanners)
- Instrumentation and Control Devices
- Radio-Controlled Models and Miniature Gearboxes
- Any compact mechanism requiring reliable, high-speed rotation with minimal space.
