6308-2ZJEM Bearing Product Overview & Core Advantages
The 6308-2ZJEM is a single row deep groove ball bearing designed for exceptional performance in demanding applications. Engineered with shielded protection on both sides, this bearing offers reliable operation by effectively excluding contaminants while retaining lubrication. Manufactured to ABEC 1 | ISO P0 tolerance standards, it provides consistent precision for general industrial use. Its robust construction from chrome steel ensures high durability and a long service life, making it a cost-effective and dependable solution for a wide range of machinery.
6308-2ZJEM Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 6308 | Basic bearing designation indicating a metric single row deep groove ball bearing with a 40mm bore, 90mm OD, and 23mm width. |
| 2Z | Identifies the bearing as having shielded protection on both sides. This provides excellent defense against solid contaminants. |
| JEM | Specifies the radial internal clearance group and potentially other manufacturer-specific design features related to performance optimization. |
6308-2ZJEM Bearing Structural Features & Performance Benefits
The performance of the 6308-2ZJEM is derived from its fundamental design and material selection. The single row deep groove raceway geometry is optimized to handle significant radial loads, with a dynamic load rating of 915 lbf and a static load rating of 5395 lbf. The use of chrome steel for all critical components (rings, balls, cage) ensures high strength and resistance to wear. The shielded (2Z) design is a key feature, protecting the internal components from dust and debris, which contributes to a longer operational life and reduced maintenance needs. With a limiting speed of 7,500 rpm, it is suitable for a wide range of operational speeds. The standard CN radial internal clearance makes it versatile for most common operating conditions.
6308-2ZJEM Bearing Typical Application Areas
The 6308-2ZJEM is a versatile component found in numerous industrial sectors. Its balanced combination of load capacity, speed capability, and contaminant protection makes it ideal for applications such as:
- Electric Motors and Gearboxes
- Industrial Pumps and Fans
- Material Handling Conveyors
- Agricultural Machinery
- General Industrial Machinery requiring reliable radial support
