MF115zz Bearing Product Overview & Core Advantages
The MF115zz is a metric miniature ball bearing featuring a single row design with integral shielded seals (zz). Engineered for precision and reliability in compact assemblies, this bearing is designed to primarily handle radial loads efficiently. Its small footprint, with a 5mm bore and 11mm outside diameter, makes it ideal for applications where space is at a premium. Manufactured to ABEC1 tolerance standards, it offers consistent performance and is pre-lubricated for immediate use, ensuring smooth operation and long service life in a wide temperature range.
MF115zz Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning | Significance |
|---|---|---|
| MF115 | Bearing series and size designation | Indicates a specific miniature bearing series with a 5mm bore, 11mm OD, and 4mm width. |
| zz | Double-sided shielded (non-contact) | Provides effective protection against contamination from both sides while maintaining high-speed capability with minimal friction. |
MF115zz Bearing Structural Features & Performance Benefits
- Robust Construction: The bearing utilizes chrome steel rings and balls for high durability and wear resistance. The stainless steel cage ensures precise ball guidance and stability.
- Radial Load Capacity: Optimized for handling radial dynamic loads up to 137 lbf, making it suitable for a variety of light to moderate load applications.
- High-Speed Performance: The combination of the stainless steel cage and shielded design allows for a limiting speed of 45,000 rpm, ideal for fast-rotating components.
- Contamination Protection: The 300 series stainless steel shields (zz) effectively guard the internal components against dust and debris, enhancing reliability and reducing maintenance needs.
- Precision Internal Clearance: Features an MC3 radial internal clearance (0.002mm to 0.013mm), providing optimal running precision for smooth and quiet operation.
MF115zz Bearing Typical Application Areas
This miniature shielded bearing is commonly specified in:
- Small Precision Motors (e.g., stepper motors, DC motors)
- Office Automation Equipment (e.g., printers, scanners, copiers)
- Medical Devices and Instrumentation
- Radio Control Models and Drones
- Computer Cooling Fans and various small gearboxes.
