SFR0 Bearing Product Overview & Core Advantages
The SFR0 is a miniature single row deep groove ball bearing engineered for precision applications requiring compact design and reliable performance. Manufactured entirely from stainless steel, it offers excellent corrosion resistance. This bearing is designed to handle primarily radial loads and is characterized by its open design, which allows for versatile lubrication options. Its small size, high limiting speed of 99,000 rpm, and ABEC1 precision make it ideal for high-speed, compact mechanisms demanding consistent operation.
SFR0 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| SFR0 | Indicates a specific series of miniature, stainless steel, deep groove ball bearings. |
| Open (No Seal/Shield suffix) | The bearing has no integral seals or shields, allowing for maximum speed and custom lubrication but requiring a clean operating environment. |
SFR0 Bearing Structural Features & Performance Benefits
- All-Stainless Steel Construction: The rings, balls, and cage are made from stainless steel, providing superior corrosion resistance and suitability for harsh environments or washdown applications.
- High-Speed Capability: The open design and precision ABEC1 tolerance minimize friction and heat generation, enabling a high limiting speed for its size class.
- Precision Performance: Manufactured to ABEC1 tolerance class with a controlled radial internal clearance (MC3), ensuring smooth and quiet operation with minimal runout.
- Compact and Lightweight: With a bore diameter of just 0.046875" and a weight of only 0.12g, it is designed for space-constrained and weight-sensitive applications.
SFR0 Bearing Typical Application Areas
This bearing is ideally suited for:
- Small Precision Motors and stepper motors
- Medical Devices and dental handpieces
- Optical Encoders and instrumentation
- RC Models and drones
- Office automation equipment and small gearboxes
