SR3 2rs Bearing Product Overview & Core Advantages
The SR3 2RS is a single row deep groove ball bearing designed for exceptional performance in compact, precision applications. Engineered with inch system dimensions, this sealed bearing offers reliable radial load capacity and is constructed entirely from stainless steel for superior corrosion resistance. Its key advantages include a robust design for smooth operation, extended service life due to integrated sealing, and compliance with RoHS and REACH standards, making it a dependable choice for demanding environments.
SR3 2rs Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| SR3 | Denotes the bearing series with a 3/16" (0.1875") bore diameter. |
| 2RS | Indicates the bearing is fitted with two rubber contact seals (RS), one on each side. This provides excellent protection against contaminants and retains lubricant. |
SR3 2rs Bearing Structural Features & Performance Benefits
- Robust Construction & Corrosion Resistance: The bearing rings, balls, and cage are manufactured from stainless steel, providing excellent resistance to rust and corrosion, ideal for harsh or washdown environments.
- Effective Sealing: The dual nitrile rubber contact seals (2RS) effectively shield the internal components from dust, moisture, and other contaminants while retaining the lubricant, enhancing bearing life and reliability.
- Precision & Smooth Operation: Built to ABEC1 tolerance class with a MC3 radial internal clearance, this bearing ensures consistent and smooth running performance, minimizing vibration and noise.
- High-Speed Capability: With a limiting speed of 38,700 rpm, it is suitable for applications requiring high rotational velocities.
SR3 2rs Bearing Typical Application Areas
This bearing is ideally suited for a wide range of applications where compact size, corrosion resistance, and reliability are critical. Key sectors include:
- Precision Instruments and optical devices
- Small Electric Motors and gearboxes
- Medical Equipment and dental handpieces
- Food Processing Machinery (due to stainless steel construction)
