SMF95 Bearing Product Overview & Core Advantages
The SMF95 is a metric single row deep groove ball bearing engineered for precision applications requiring compact dimensions and reliable performance. Constructed entirely from stainless steel, it offers excellent corrosion resistance. This bearing is designed to primarily handle radial loads and is characterized by its open design and ABEC1 precision class, making it a cost-effective solution for high-speed operations up to 45,000 rpm where space is at a premium.
Model Code Breakdown
| Code Segment | Technical Meaning |
|---|---|
| SMF95 | Standard model designation for this specific bearing size (5mm bore, 9mm OD). |
| Open | No seals or shields, allowing for higher speeds and easy re-lubrication. Requires a clean operating environment. |
| ABEC1 | Defines the tolerance class, ensuring standardized dimensional accuracy and running precision. |
| MC3 | Specifies the radial internal clearance group (0.002mm to 0.013mm), suitable for a wide range of operating conditions. |
SMF95 Bearing Structural Features & Performance Benefits
- Compact & Lightweight Design: With a bore diameter of 5mm, an outside diameter of 9mm, and a width of just 2.5mm, this bearing is ideal for miniaturized assemblies. Its low weight of 0.62g minimizes inertia.
- High-Speed Capability: The open construction and optimized stainless steel cage contribute to a high limiting speed of 45,000 rpm, making it a true high-speed bearing.
- Robust Load Capacity: Features a radial dynamic load rating of 74 lbf and a static load rating of 27 lbf, providing reliable performance under demanding radial loads.
- Corrosion Resistance: All components, including rings, balls, and cage, are made from stainless steel, ensuring long service life in humid or corrosive environments.
- Standard Internal Clearance: The MC3 clearance group offers operational versatility across various fit and temperature conditions.
SMF95 Bearing Typical Application Areas
This bearing is commonly used in:
- Small Precision Motors and stepper motors
- Medical and Dental Handpieces
- High-Speed Spindles in miniature machinery
- Office automation equipment (e.g., printers, scanners)
- Instrumentation and precision mechanical guides
- Radio-controlled models and drones
