61906 Bearing Product Overview & Core Advantages
The 61906 is a metric single row deep groove ball bearing engineered for high-precision radial load applications. Characterized by its open design and manufactured to a P6 tolerance class, this bearing offers exceptional running accuracy and rotational stability. Its compact cross-section, with a 9 mm width, makes it an ideal solution for space-constrained assemblies requiring reliable performance under substantial radial dynamic loads of up to 1637 lbf.
61906 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 6 | Single row deep groove ball bearing |
| 1 | Extra Light Series (Cross-section) |
| 9 | Bore diameter code (30 mm) |
| 06 | Bore diameter series identifier |
| Open (No Seal) | No contact seals, enabling higher limiting speeds and suitability for centralized lubrication systems. |
| P6 Tolerance | Indicates superior dimensional and running accuracy compared to standard bearings. |
61906 Bearing Structural Features & Performance Benefits
- High Precision & Rigidity: The P6 tolerance class and tight dimensional tolerances on the bore diameter and outside diameter ensure minimal runout and vibration, providing stable and precise shaft support.
- Optimized Load Capacity: The deep groove raceway and high-grade chrome steel construction are designed to handle significant radial dynamic loads efficiently.
- High-Speed Capability: The open design and stainless steel cage reduce friction and allow for a high limiting speed of 19,000 rpm, making it suitable for demanding rotational applications.
- Robust Material Selection: Rings and balls made from chrome steel offer high hardness and wear resistance, while the stainless steel cage provides excellent corrosion resistance and cage integrity.
