6318 Bearing Product Overview & Core Advantages
The 6318 is a single row deep groove ball bearing designed for exceptional performance in a wide range of industrial applications. As a metric bearing with an open design, it excels at handling high radial loads while also accommodating moderate axial loads in both directions. Its construction from high-grade chrome steel ensures durability and long service life, making it a reliable and cost-effective solution for demanding environments that require high reliability and consistent operation.
6318 Bearing Model Code Explained, Specifications & Naming Convention
| Model Segment | Interpretation | Technical Significance |
|---|---|---|
| 63 | Series Code | Indicates a medium-duty bearing series with robust dimensions and load capacity. |
| 18 | Bore Diameter Code | Signifies a standard bore diameter of 90 mm (calculated as 18 x 5 = 90mm). |
| (No Suffix) | Standard Configuration | Denotes an open (unsealed) bearing with a stainless steel cage, standard CN radial internal clearance, and ABEC-1 tolerance class. Lubrication is required by the user. |
