SMF115 Bearing Product Overview & Core Advantages
The SMF115 is a metric single row deep groove ball bearing designed for high-performance applications requiring precision and reliability. Constructed entirely from stainless steel, it offers excellent corrosion resistance. Its compact design, with a 5 mm bore and 4 mm width, provides a space-saving solution for assemblies with limited radial space, while the integrated flange ensures secure and simplified mounting. This bearing is engineered to handle radial loads efficiently and is optimized for high-speed operation up to 40,500 rpm.
SMF115 Bearing Model Code Explained, Specifications & Naming Convention
| Model Segment | Interpretation | Technical Significance |
|---|---|---|
| SMF115 | Base Model | Denotes a flanged, single row deep groove ball bearing with specific dimensions (5x11x4 mm). |
| (Open) | Seal Type | The bearing is supplied open (unsealed), allowing for custom lubrication schemes but requiring a clean operating environment. |
| ABEC1 | Tolerance Class | Specifies standard precision tolerances for bore, outside diameter, and width, suitable for a wide range of general applications. |
| MC3 | Internal Clearance | Defines a normal radial internal clearance (0.002mm to 0.013mm), which is typical for most operating conditions. |
SMF115 Bearing Structural Features & Performance Benefits
- Compact & Robust Flange Design: The integrated flange (Ø12.6 mm) provides positive location and ease of assembly, eliminating the need for complex housing shoulders and reducing overall component size and weight.
- High-Speed Capability: The stainless steel cage and optimized internal geometry with 8 precision balls enable smooth operation at limiting speeds of 40,500 rpm, making it ideal for high-speed spindles and rotors.
- Corrosion Resistance: Manufactured entirely from stainless steel, including rings, balls, and cage, the bearing is well-suited for applications exposed to moisture, chemicals, or requiring frequent washdowns.
- Precision Performance: With an ABEC1 tolerance class and controlled radial internal clearance, the SMF115 ensures consistent running accuracy and low vibration for smooth operation.
SMF115 Bearing Typical Application Areas
- Small Precision Motors: Ideal for spindle support in miniature DC motors and stepper motors.
- Medical and Dental Equipment: Used in handheld tools, pumps, and scanners where corrosion resistance and reliability are critical.
- Office Automation: Found in scanners, printers, and copiers for paper feed rollers and scanner heads.
- Instrumentation and Control Systems: Supports shafts in encoders, gyroscopes, and other precision measurement devices.
