SMR126 2rs Bearing Product Overview & Core Advantages
The SMR126 2RS is a metric single row deep groove ball bearing engineered for precision and reliability in compact applications. Constructed entirely from stainless steel for superior corrosion resistance, this bearing is pre-lubricated and sealed with two Nitrile Rubber (2RS) contact seals, making it a maintenance-free solution. It is designed to primarily handle radial loads and is characterized by its low friction, quiet operation, and long service life, making it ideal for applications demanding high precision and durability within a wide temperature range.
SMR126 2rs Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| SMR126 | Basic bearing designation indicating a metric, single row deep groove ball bearing with a 6mm bore, 12mm OD, and 4mm width. |
| 2RS | Signifies the bearing is equipped with two (2) Nitrile Rubber (RS) contact seals on both sides. This provides excellent protection against contaminants and retains lubricant. |
SMR126 2rs Bearing Structural Features & Performance Benefits
- Robust Stainless Steel Construction: All core components, including rings, balls, and cage, are made from stainless steel, offering excellent resistance to corrosion and enabling use in harsh environments.
- Effective Sealing with 2RS Design: The two Nitrile Rubber contact seals effectively shield the bearing interior from dust, moisture, and other contaminants while retaining the factory-applied lubricant, ensuring a long, maintenance-free operational life.
- Optimized for Radial Loads: The deep groove raceway and stainless steel ball design are optimized to efficiently carry radial dynamic and static loads (123 lbf and 48 lbf respectively).
- Precision ABEC1 Tolerance: Manufactured to ABEC1 precision class standards, ensuring consistent performance, smooth operation, and reliable bearing dimensions for a wide range of applications.
- Wide Operating Temperature Range: Suitable for use in temperatures from -30°C to 110°C, providing versatility for various operational conditions.
SMR126 2rs Bearing Typical Application Areas
This versatile and compact bearing is commonly found in:
- Small Electric Motors (e.g., in fans, pumps, and power tools)
- Precision Instruments and Medical Devices
- Office Automation Equipment (printers, scanners)
- Food Processing and Packaging Machinery
- Various light-duty industrial machinery requiring corrosion-resistant components
