SR156 2rs Bearing Product Overview & Core Advantages
The SR156 2RS is a single row deep groove ball bearing designed for high performance in demanding applications. This inch-series bearing features a robust sealed construction and is manufactured entirely from stainless steel, providing excellent corrosion resistance. Its primary advantage lies in its ability to handle radial loads efficiently while offering reliable operation across a wide temperature range. The inclusion of integral seals makes it a pre-lubricated, low-maintenance component ideal for applications requiring long service life and consistent performance.
SR156 2rs Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| SR156 | Standard bearing series designation with a bore diameter of 0.1875" and an outside diameter of 0.3125". |
| 2RS | Indicates the bearing is equipped with two rubber contact seals (RS), one on each side. This provides superior protection against contaminants and retains lubrication. |
SR156 2rs Bearing Structural Features & Performance Benefits
- Robust Sealed Design: The dual Nitrile rubber contact seals (2RS) effectively shield the internal components from dust, moisture, and other contaminants, significantly enhancing bearing life and reliability in harsh environments.
- High-Quality Materials: Constructed entirely from stainless steel for the rings, balls, and cage, this bearing offers excellent resistance to corrosion and is suitable for use in wash-down or chemically aggressive settings.
- Optimized Internal Geometry: With a radial internal clearance of MC3 and a complement of 10 precision balls, the bearing is engineered for smooth, low-vibration operation, contributing to its limiting speed of 47,700 rpm.
- Pre-Lubricated for Service Life: The bearing comes pre-lubricated, making it ready for immediate installation and ensuring optimal performance from the start without the need for initial maintenance.
SR156 2rs Bearing Typical Application Areas
The SR156 2RS is ideally suited for a variety of compact and precision-driven applications, including:
- Small Electric Motors and miniature gearboxes
- Medical and Dental Handpieces requiring high-speed, sterile operation
- Precision Instruments and optical devices
- Food Processing Equipment where corrosion resistance and cleanability are critical
