MF104 Bearing Product Overview & Core Advantages
The MF104 is a metric single row deep groove ball bearing engineered for compact, high-precision applications requiring reliable radial load support. Its open design and ABEC1 precision class ensure smooth operation and accurate rotational performance. This bearing is characterized by its minimal cross-section (4mm bore, 10mm OD, 3mm width) and lightweight construction (1.04g), making it an ideal component for space-constrained assemblies where precision and reliability are paramount.
MF104 Bearing Model Code Explained, Specifications & Naming Convention
The MF104 model code indicates a standard, open deep groove ball bearing. While it does not carry complex suffixes, its specifications define its performance profile:
- MF104: Standard model designation for a metric, single row deep groove ball bearing.
- Open (No Seal): Allows for custom lubrication strategies but requires a clean operating environment.
- ABEC1: Denotes the precision tolerance class.
- MC3: Specifies the standard radial internal clearance group.
MF104 Bearing Structural Features & Performance Benefits
The MF104's performance stems from its optimized single row construction and material selection:
- High-Grade Materials: Both rings and ball material are manufactured from Chrome Steel, providing excellent wear resistance and durability. The stainless steel cage ensures cage integrity and corrosion resistance.
- Radial Load Capacity: With a dynamic load rating of 136 lbf and a static load rating of 49 lbf, it is designed to handle significant radial forces for its size.
- Precision Engineering: The ABEC1 tolerance class and controlled radial internal clearance (0.002mm to 0.013mm) contribute to low noise and vibration, enabling smooth high-speed operation up to 48,000 rpm.
- Compact & Lightweight: The slim bearing dimensions (4x10x3mm) and low weight make it perfect for miniaturized devices.
MF104 Bearing Typical Application Areas
The MF104's compact size, precision, and high-speed capability make it suitable for a wide range of applications, including:
- Small Precision Electric Motors (e.g., drones, RC models)
- Medical and Dental Handpieces
- Office Automation Equipment (printers, scanners)
- Instrumentation and Measurement Devices
- Computer Cooling Fans
- Small Gearboxes and Actuators
