MF52 2rs Bearing Product Overview & Core Advantages
The MF52 2RS is a metric miniature ball bearing designed for applications demanding compact size and reliable performance. This single row deep groove ball bearing features integral rubber seals (2RS) on both sides, providing excellent protection against contamination. Its primary advantages include a compact design with a 2mm bore, suitability for radial loads, and robust construction using chrome steel rings and balls for durability. Engineered to ABEC1 precision tolerances, it offers a dependable solution for small-scale, precision mechanisms.
Model Code In-Depth Explanation
| Code Segment | Technical Meaning |
|---|---|
| MF52 | The base bearing designation, indicating a specific series of miniature metric bearings with a 2mm bore, 5mm outside diameter, and 2.5mm width. |
| 2RS | Denotes two (2) integral Rubber Seals (RS), one on each side. This provides superior protection against dust, moisture, and other contaminants, helping to retain lubrication. |
MF52 2rs Bearing Structural Features & Performance Benefits
- Robust Sealing: The Nitrile Rubber (NBR) seals (2RS) effectively shield the internal components from contaminants, extending bearing life and making it suitable for unclean environments. This design also helps retain the pre-applied lubricant.
- High-Quality Materials: Constructed with chrome steel rings and balls, the bearing provides high hardness and wear resistance. The stainless steel cage ensures smooth operation and stability at the specified limiting speed.
- Precision & Clearance: Manufactured to ABEC1 tolerance class, it guarantees consistent dimensional accuracy. The MC3 radial internal clearance (0.002mm to 0.013mm) is optimized for a wide range of operating conditions.
- Compact & Lightweight: With an outer diameter of just 5mm and a weight of only 0.19g, it is ideal for space-constrained and weight-sensitive applications.
MF52 2rs Bearing Typical Application Areas
- Small Precision Motors: Ideal for use in miniature DC motors, stepper motors, and coreless motors.
- Medical Devices: Suitable for small instruments, dental handpieces, and pump mechanisms.
- Office Automation: Commonly used in printers, scanners, and small cooling fans.
- Robotics & RC Models: Provides reliable support in small joints, gearboxes, and drone motors.
- Precision Instruments: Used in gauges, encoders, and other sensitive measurement equipment.
