SMF148 Bearing Product Overview & Core Advantages
The SMF148 is a metric single row deep groove ball bearing engineered for compact applications requiring reliable radial load capacity. Constructed entirely from stainless steel (rings, balls, and cage), it offers excellent corrosion resistance. Its open design allows for versatile lubrication options, while the integrated flange facilitates secure and precise mounting. This bearing is ideal for applications demanding high precision, compact dimensions, and consistent performance in various environments.
Model Code Breakdown
| Code Segment | Technical Meaning |
|---|---|
| SMF148 | Standard model designation for this specific flanged bearing series with an 8mm bore and 14mm outside diameter. |
| Open (Seal Type) | No integral seals or shields. This allows for higher limiting speeds and custom lubrication schemes but requires a clean operating environment or external sealing. |
SMF148 Bearing Structural Features & Performance Benefits
- Compact & Lightweight Design: With a width of just 3.5 mm and a weight of only 2.13 g, this bearing is perfect for space-constrained and weight-sensitive applications.
- Integrated Flange: The flange (15.6 mm outer diameter) simplifies axial positioning and mounting, enhancing assembly accuracy and stability.
- Full Stainless Steel Construction: Provides superior corrosion resistance, making it suitable for harsh environments, including those requiring washdown or exposure to certain chemicals.
- Optimized Internal Geometry: Features 10 precision balls with a diameter of 1.588 mm, contributing to smooth operation and efficient radial load distribution.
- Standard ABEC1 Precision: Ensures consistent running accuracy and low noise and vibration levels for general precision applications.
- MC3 Radial Clearance: The specified internal clearance (0.002mm to 0.013mm) is suitable for a wide range of operating conditions, providing a balance between temperature management and running precision.
SMF148 Bearing Typical Application Areas
- Small Precision Electric Motors and Miniature Gearboxes
- Medical and Dental Hand Tools
- Optical Encoders and Precision Instrumentation
- Office Automation Equipment (e.g., Printers, Scanners)
- Robotics and Small Actuators
- Radio-Controlled Models and Drones
