SF623 Bearing Product Overview & Core Advantages
The SF623 is a metric single row deep groove ball bearing engineered for high performance in compact spaces. Constructed entirely from stainless steel, it offers excellent corrosion resistance and is designed to handle primarily radial loads. Its open design allows for versatile lubrication options, making it suitable for applications demanding cleanliness and specific lubricant compatibility. With a precision ABEC1 tolerance class, this bearing provides reliable and smooth operation, ideal for high-speed scenarios up to 45,000 rpm.
SF623 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| SF623 | The base model number, defining the core bearing dimensions (3mm bore, 10mm OD, 4mm width). |
| Open (Seal Type) | No built-in seals or shields. This allows for high-speed operation and custom lubrication but requires a clean operating environment. |
| MC3 (Clearance) | Specifies a radial internal clearance group of 0.002mm to 0.013mm, suitable for a wide range of operational temperatures and fits. |
| ABEC1 | The precision tolerance class, ensuring consistent dimensional accuracy and smooth running. |
SF623 Bearing Structural Features & Performance Benefits
The SF623's performance is derived from its robust construction. The single row deep groove raceway and complement of seven precision balls provide a low-friction path for high-speed operation. The all-stainless steel construction, including the cage, ensures dimensional stability and resistance to corrosion, extending service life. The MC3 radial internal clearance is optimized to manage thermal expansion during high-speed rotation, preventing premature failure. The flanged outer ring (11.5mm diameter) facilitates secure and simplified mounting, enhancing positional accuracy.
