SMF104 2rs Bearing Product Overview & Core Advantages
The SMF104 2RS is a single row deep groove ball bearing designed for exceptional performance in compact applications. Engineered with stainless steel construction throughout (rings, balls, and cage), it offers superior corrosion resistance. Its key advantage lies in its sealed design (2RS), which provides robust protection against contaminants while retaining lubricant, making it a low-maintenance and highly reliable solution for applications demanding long service life and consistent operation under radial loads.
SMF104 2rs Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| SMF104 | Basic bearing designation indicating a metric, flanged, single-row deep groove ball bearing with a 4mm bore, 10mm OD, and 4mm width. |
| 2RS | Contact Nitrile Rubber Seals on both sides. This provides excellent protection against dust and moisture ingress, ensuring a long-lasting, maintenance-free operation by retaining the lubricant effectively. |
SMF104 2rs Bearing Structural Features & Performance Benefits
- Robust Sealing & Corrosion Resistance: The dual 2RS seals and all-stainless steel construction make this bearing ideal for harsh environments, preventing contamination and resisting corrosion.
- High-Speed Capability: The stainless steel cage and optimized internal geometry contribute to a high limiting speed of 43,200 rpm, suitable for demanding high-velocity applications.
- Precision & Stability: Manufactured to ABEC1 tolerance class with a controlled MC3 radial internal clearance (0.002mm to 0.013mm), ensuring smooth and precise running with minimal vibration.
- Flanged Design: The integrated flange (11.6mm OD) simplifies mounting and positioning, enhancing axial location security and reducing assembly complexity and cost.
SMF104 2rs Bearing Typical Application Areas
This versatile miniature bearing is ideally suited for:
- Small Precision Motors (e.g., in drones, RC models, medical devices)
- Office Automation Equipment (printers, scanners, copiers)
- Instrumentation and Measurement Devices
- Low-Torque, High-Speed Spindles
- Various industrial machinery requiring compact, reliable, and sealed bearing solutions.
