6008 Bearing Product Overview & Core Advantages
The 6008 is a metric single row deep groove ball bearing designed for reliable performance in general industrial applications. This open-type bearing offers excellent versatility and is engineered to handle primarily radial loads, making it a fundamental component in various machinery. Manufactured with chrome steel rings and balls and a stainless steel cage, it provides durability and consistent operation. Its ABEC-1 precision class and standardized dimensions ensure easy integration and reliable service, establishing it as a cost-effective solution for standard speed and load requirements.
6008 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 6008 | Standard bearing designation indicating a metric, single row deep groove ball bearing with a 40mm bore, 68mm OD, and 15mm width. |
| Open | No seals or shields. This allows for higher limiting speeds and requires external lubrication, offering flexibility in application-specific lubrication choices. |
| CN Clearance | Standard radial internal clearance for normal operating conditions and fits. |
| ABEC-1 | The tolerance class defining standard precision levels for runout and dimensional accuracy. |
6008 Bearing Structural Features & Performance Benefits
