S627 Bearing Product Overview & Core Advantages
The S627 is a single row deep groove ball bearing designed for exceptional performance in radial load applications. Constructed entirely from stainless steel, it offers superior corrosion resistance, making it ideal for demanding environments. This ABEC 1 precision bearing provides reliable operation and is engineered for applications requiring a compact design with a 7 mm bore. Its open design allows for versatile lubrication options to suit specific operational needs.
S627 Bearing Model Code Explained, Specifications & Naming Convention
| Model Segment | Technical Meaning |
|---|---|
| S627 | Standard designation for a single row deep groove ball bearing with a 7 mm bore and 22 mm outside diameter. |
| Open | No integral seals or shields. This allows for higher limiting speeds and custom lubrication but requires a clean operating environment or external sealing. |
S627 Bearing Structural Features & Performance Benefits
- Full Stainless Steel Construction: The rings, balls, and cage are manufactured from stainless steel, providing excellent resistance to rust and corrosion, which is critical for applications exposed to moisture or chemicals.
- Optimized Radial Load Capacity: The deep groove raceway and complement of 7 precision balls enable high radial dynamic load rating (566 lbf) for its compact size, ensuring long service life under load.
- High-Speed Capability: The open design and stainless steel cage contribute to a high limiting speed of 27,000 rpm, suitable for demanding rotational applications.
- Precision Performance: Manufactured to ABEC 1 tolerance class, this bearing offers precise running accuracy and low vibration for smooth operation.
- Standard Internal Clearance (MC3): Provides an optimal fit for most general applications, balancing operational temperature and load conditions.
S627 Bearing Typical Application Areas
- Medical and Dental Equipment
- Food Processing and Packaging Machinery
