1206 Bearing Product Overview & Core Advantages
The 1206 metric ball bearing is a double row open-type precision component engineered for demanding applications requiring high radial load capacity and operational stability. Featuring a cylindrical bore with tight dimensional tolerances and manufactured from chrome steel, this bearing delivers exceptional durability and reliability. Its compact design, characterized by a 30 mm bore and 16 mm width, makes it an ideal solution for space-constrained assemblies where high rigidity and consistent performance under substantial radial loads are paramount.
1206 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Significance |
|---|---|
| 1206 | Standard metric series designation indicating bearing dimensions: 30mm bore, 62mm OD, 16mm width. |
| Open (No Seal Code) | No contact seals, enabling higher limiting speeds and optimal for systems with external lubrication. |
| Lubricated | Factory pre-lubricated for immediate operation, reducing initial setup complexity. |
1206 Bearing Structural Features & Performance Benefits
