S629 Bearing Product Overview & Core Advantages
The S629 is a metric single row deep groove ball bearing engineered for reliable performance in radial load applications. Constructed entirely from stainless steel, it offers excellent corrosion resistance. This bearing is characterized by its compact dimensions (9mm bore, 26mm OD, 8mm width) and is manufactured to ABEC1 precision tolerances, ensuring smooth operation and consistent performance. Its open design allows for versatile lubrication options to suit specific operational needs.
Model Code Breakdown
| Code Segment | Technical Meaning |
|---|---|
| S629 | Basic bearing designation for a single row deep groove ball bearing with a 9mm bore diameter. |
| Open (No Seal/Shield suffix) | Indicates the bearing is supplied without seals or shields, allowing for high-speed operation and custom lubrication. |
S629 Bearing Structural Features & Performance Benefits
- All-Stainless-Steel Construction: The rings, balls, and cage are made from stainless steel, providing superior resistance to rust and corrosion, making it ideal for harsh environments or washdown applications.
- Deep Groove Raceway: The geometry of the deep groove raceway is optimized for handling radial loads efficiently, ensuring stable operation.
- High-Speed Capability: The open design and stainless steel cage contribute to a high limiting speed of 25,200 rpm, suitable for demanding applications.
- Precision Performance: Manufactured to ABEC1 tolerance class with a controlled radial internal clearance (MC3 group), this bearing delivers consistent running accuracy and low vibration.
