MR106 2rs Bearing Product Overview & Core Advantages
The MR106 2RS is a metric single row deep groove ball bearing designed for reliable performance in compact spaces. Its primary advantage lies in its sealed construction (2RS), which provides effective protection against contaminants while retaining lubrication, making it suitable for applications requiring long-term, maintenance-free operation. Engineered with chrome steel rings and balls and a stainless steel cage, this bearing offers a robust solution for handling radial loads and is characterized by its small cross-section, high precision ABEC1 tolerance class, and consistent operation within a wide temperature range.
Model Code Breakdown
| Code Segment | Technical Meaning | Benefit |
|---|---|---|
| MR106 | Standard bearing designation indicating a metric, single row deep groove ball bearing with a 6mm bore, 10mm OD, and 3mm width. | Defines the core bearing dimensions and type for easy identification and interchangeability. |
| 2RS | Bearing is fitted with contact seals on both sides, made of Nitrile Rubber (NBR). | Provides superior contamination exclusion and lubricant retention, enabling extended service life and reduced maintenance. |
MR106 2rs Bearing Structural Features & Performance Benefits
- Deep Groove Raceway & Single Row Design: Optimized for high-capacity radial load support. The geometry allows for smooth operation and low running torque.
- Sealed for Life (2RS): The nitrile rubber contact seals effectively shield the internal components from dust, moisture, and other contaminants. This design, combined with the required initial lubrication, creates a maintenance-free solution for the bearing's operational lifespan.
- Stainless Steel Cage: Ensures precise guidance of the 10 chrome steel balls, contributing to stable operation, reduced friction, and suitability for the specified limiting speed of 45,000 rpm.
- Precision & Clearance: Manufactured to ABEC1 tolerance class with a MC3 radial internal clearance (0.002mm to 0.013mm), ensuring consistent performance, low noise, and vibration in a variety of operating conditions.
MR106 2rs Bearing Typical Application Areas
The MR106 2RS is ideally suited for small, high-speed, and precision mechanisms where reliability and contamination protection are critical. Common applications include:
- Small Electric Motors (e.g., drones, precision tools)
- Office Automation Equipment (printers, scanners)
- Medical and Dental Handpieces
- Precision Instruments and Gauges
- Computer Cooling Fans
- Radio-Controlled Models and Small Gearboxes
