S694 Bearing Product Overview & Core Advantages
The S694 is a metric single row deep groove ball bearing engineered for high-performance applications requiring compact design and reliable operation. Constructed entirely from stainless steel, it offers excellent corrosion resistance. This bearing is designed to primarily accommodate radial loads and is characterized by its high limiting speed and ABEC1 precision class, making it a robust and cost-effective solution for various precision mechanisms.
S694 Bearing Model Code Explained, Specifications & Naming Convention
| Model Segment | Interpretation | Technical Significance |
|---|---|---|
| S694 | Basic Model Number | Denotes a specific series of miniature deep groove ball bearings with a 4mm bore, 11mm OD, and 4mm width. |
| (No Suffix) | Open, Unsealed | Indicates the bearing is open, allowing for optimal lubrication access and heat dissipation, but requires a clean operating environment or external sealing. |
S694 Bearing Structural Features & Performance Benefits
- Compact & Lightweight Design: With dimensions of 4x11x4 mm and a weight of only 1.69 grams, it is ideal for space-constrained and weight-sensitive applications.
