MF84zz Bearing Product Overview & Core Advantages
The MF84zz is a miniature single row deep groove ball bearing designed for compact applications requiring reliable performance. This shielded bearing excels in handling radial loads and is engineered for smooth operation in high-speed scenarios. Its compact dimensions (4mm bore, 8mm OD) and lightweight construction (0.64g) make it an ideal choice for precision instruments and small machinery where space is at a premium. The bearing is supplied with a required lubrication fill, ensuring immediate readiness for installation and operation.
MF84zz Bearing Model Code Explained, Specifications & Naming Convention
- MF: Miniature Flanged series, indicating the bearing's small size and integrated flange for axial location.
- 84: Standard size designation for a 4mm bore, 8mm outside diameter bearing.
- zz: Specifies that the bearing is fitted with non-contact shields (Z-shields) on both sides. This provides effective protection against contamination while minimizing friction and torque, contributing to the high limiting speed.
MF84zz Bearing Structural Features & Performance Benefits
Robust Construction for Durability: Manufactured from Chrome Steel for rings and balls, and a Stainless Steel cage, this bearing offers excellent resistance to wear and corrosion, ensuring a long service life.
Optimized Load Capacity: With a dynamic load rating of 76 lbf and a static load rating of 25 lbf, it is well-suited for applications with continuous radial loads.
High-Speed Capability: The combination of a stainless steel cage, non-contact shields, and optimized internal geometry allows for a high limiting speed of 56,000 rpm.
Precision and Stability: Built to ABEC1 tolerance class and featuring a controlled radial internal clearance (MC3 group), this bearing provides consistent, low-vibration operation essential for precision devices.
Simplified Mounting: The integrated flange (9.2mm outer diameter) facilitates easy and secure axial positioning within a housing, simplifying assembly.
MF84zz Bearing Typical Application Areas
This miniature flanged bearing is commonly specified in:
- Small Precision Motors (e.g., in drones, RC models)
- Medical and Dental Handpieces
- Office Automation Equipment (printers, scanners)
- Instrumentation and Control Devices
- Computer Cooling Fans
