SR166 2rs Bearing Product Overview & Core Advantages
The SR166 2RS is a sealed single row deep groove ball bearing designed for reliable performance in demanding applications. Engineered with stainless steel construction throughout its rings, balls, and cage, it offers excellent corrosion resistance. Its primary advantage lies in its ability to handle radial loads efficiently while the integrated nitrile rubber seals (2RS) provide robust protection against contaminants, making it a durable and long-lasting solution for compact spaces requiring dependable operation.
SR166 2rs Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| SR166 | Standard bearing series designation with specific inch dimensions. |
| 2RS | Indicates contact seals on both sides, made of Nitrile Rubber (NBR), providing superior exclusion of moisture and debris. |
SR166 2rs Bearing Structural Features & Performance Benefits
- Robust Sealing: The double-sided contact seals (2RS) effectively shield the internal components from contaminants, significantly enhancing bearing life in harsh environments.
- Corrosion Resistance: Manufactured entirely from stainless steel, this bearing is ideal for applications exposed to moisture, chemicals, or requiring washdown.
- Precision & Smooth Operation: Built to ABEC1 tolerance standards with a specified radial internal clearance (MC3 group), ensuring consistent performance and low vibration.
- Compact Design & Load Capacity: With a dynamic load rating of 122 lbf and a static load rating of 44 lbf, it offers a high load capacity for its small bearing dimensions (0.1875" bore x 0.375" OD x 0.125" width).
SR166 2rs Bearing Typical Application Areas
This bearing is well-suited for a variety of applications where size, reliability, and corrosion resistance are critical. Key industries and equipment include:
- Medical and Dental Equipment: Small motors, pumps, and handheld devices.
- Food and Beverage Processing: Conveyor rollers, mixers, and other machinery requiring frequent washdown.
- Precision Instruments: Optical encoders, gauges, and small robotic joints.
- Office Automation: Printers, scanners, and copiers.
- Electric Motors: Small fans and miniature motors.
