MF84 2rs Bearing Product Overview & Core Advantages
The MF84 2RS is a metric miniature ball bearing engineered for compact applications demanding reliable performance. As a single row deep groove ball bearing, it is primarily designed to accommodate radial loads efficiently. Its key advantages include a compact design with a 4mm bore and a lightweight construction of just 0.47g, making it ideal for space-constrained assemblies. The inclusion of Nitrile rubber seals (2RS) provides effective protection against contaminants, enhancing operational lifespan. Manufactured to ABEC1 precision tolerances, this bearing offers a dependable balance of performance and value for a wide range of industrial applications.
Model Code Breakdown
| Code Segment | Technical Meaning |
|---|---|
| MF84 | The base bearing designation, indicating a specific series of miniature flanged bearings. |
| 2RS | Signifies that the bearing is equipped with contact rubber seals on both sides. This provides superior protection against dust and moisture ingress compared to shielded variants. |
MF84 2rs Bearing Structural Features & Performance Benefits
- Robust Construction: Built with Chrome Steel rings and balls coupled with a Stainless Steel cage, this bearing ensures high durability and resistance to wear.
- Effective Sealing: The Nitrile rubber seals (2RS) not only protect the internal components from contaminants but also help retain lubricant, contributing to a maintenance-free operation in many environments.
- Radial 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 significant radial forces.
- Precision & Stability: Manufactured to ABEC1 tolerance class and featuring a controlled radial internal clearance (MC3: 0.002mm to 0.013mm), it provides consistent and smooth running performance.
- Compact Flange Design: The integrated flange (9.2mm outer diameter) facilitates easy and secure mounting, simplifying installation and improving positional accuracy.
