MF148 Bearing Product Overview & Core Advantages
The MF148 is a metric miniature ball bearing engineered for precision applications requiring compact design and reliable performance. This single row deep groove ball bearing features an open construction and is designed primarily to handle radial loads efficiently. Its small footprint, with a bore diameter of just 8 mm and a width of 3.5 mm, makes it ideal for space-constrained assemblies. Manufactured to ABEC1 precision class tolerances, it ensures consistent operation and is RoHS and REACH compliant, meeting modern environmental standards.
MF148 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| MF148 | Basic model number denoting a specific series of miniature, metric, single row deep groove ball bearings. |
| Open (Seal Type) | No integral seals or shields. Allows for higher speeds and custom lubrication but requires a clean operating environment. |
| MC3 (Clearance) | Specifies a greater than normal radial internal clearance (0.002mm to 0.013mm), suitable for applications with thermal expansion or where interference fits are used. |
MF148 Bearing Structural Features & Performance Benefits
- High-Precision Components: Constructed from chrome steel rings and balls with a stainless steel cage, this bearing offers excellent durability and corrosion resistance, contributing to a long service life and stable performance.
- Optimized Load Capacity: The deep groove raceway and 10 high-grade balls enable efficient handling of the specified radial dynamic load rating of 156 lbf and radial static load rating of 70 lbf.
- Compact & Lightweight Design: With a minimal cross-section and a weight of only 2.13 g, it is perfect for reducing the size and weight of miniature mechanical systems.
- Versatile Operating Range: The specified temperature range of -30°C to 110°C and a limiting speed of 38,000 rpm make it suitable for a wide array of demanding applications.
MF148 Bearing Typical Application Areas
The MF148 miniature bearing is ideally suited for:
- Small Precision Motors: Including stepper motors and coreless DC motors used in drones, robotics, and medical devices.
- Office Automation Equipment: Such as printers, scanners, and copiers where quiet, reliable rotation is critical.
- Instrumentation and Gauges: Providing smooth, low-friction movement in precision measuring equipment.
- Consumer Electronics: Used in small fans, computer disk drives, and various handheld devices.
