SMR82x 2rs Bearing Product Overview & Core Advantages
The SMR82x 2RS is a miniature deep groove ball bearing engineered for precision applications requiring compact dimensions and reliable performance. This sealed single row ball bearing is constructed entirely from stainless steel, offering excellent corrosion resistance. Its primary advantage lies in its ability to handle radial loads efficiently within a minimal footprint, making it an ideal component for high-precision, space-constrained assemblies where reliability is paramount.
SMR82x 2rs Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| SMR82x | Series designation indicating a miniature metric bearing with a 2.5mm bore and 8mm outside diameter. |
| 2RS | Signifies the bearing is equipped with two rubber seals (RS), one on each side. This provides effective protection against contaminants and retains lubricant. |
SMR82x 2rs Bearing Structural Features & Performance Benefits
- Compact & Robust Design: The single-row deep groove raceway and compact bearing dimensions (2.5mm bore, 8mm OD, 2.5mm width) provide a robust solution for miniature assemblies.
- Effective Sealing: The dual Nitrile rubber seals (2RS) effectively shield the internal components from dust, moisture, and other contaminants, while retaining the necessary lubrication.
- High-Speed Capability: With a limiting speed of 54,000 rpm, this bearing is suitable for high-speed applications, facilitated by its smooth raceways and six precision balls.
- Corrosion Resistance: Manufactured entirely from stainless steel (rings, balls, and cage), this bearing is ideal for applications exposed to corrosive environments or requiring washdown.
- Precision Grade: Manufactured to ABEC1 tolerance class with a controlled radial internal clearance (MC3: 0.002mm to 0.013mm), ensuring consistent and smooth operation.
SMR82x 2rs Bearing Typical Application Areas
This miniature deep groove ball bearing is commonly specified in:
- Small Precision Motors (e.g., drones, miniature DC motors)
- Medical and Dental Handpieces
- Optical Encoders and Precision Instruments
- Office Automation Equipment (e.g., small printers, scanners)
- Radio-Controlled Models and Miniature Robotics
