6308-2ZNRJEM Bearing Product Overview & Core Advantages
The 6308-2ZNRJEM is a single row deep groove ball bearing engineered for robust performance in demanding applications. This precision bearing features integral shielded seals and a snap ring groove on its outer ring, offering a compact and reliable solution. Its design excels at handling significant radial loads while accommodating moderate axial loads, making it ideal for applications requiring high reliability and simplified assembly. The combination of a shielded design and standard radial internal clearance ensures consistent operation across a wide temperature range.
6308-2ZNRJEM Bearing Model Code Explained, Specifications & Naming Convention
- 6308: Basic model number denoting a single row deep groove ball bearing with a 40mm bore, 90mm OD, and 23mm width.
- 2Z: Designates that the bearing is equipped with non-contact shields on both sides. These shields protect against coarse contaminants while minimizing friction.
- NR: Indicates a snap ring groove is machined onto the outer ring. This feature allows for simplified axial location within a housing.
- JEM: Represents a specific manufacturer's suffix, often related to internal manufacturing standards or material selection.
6308-2ZNRJEM Bearing Structural Features & Performance Benefits
The bearing's performance is derived from its specific construction. The single row deep groove raceway geometry is optimized for high radial load capacity. The non-contact shields (2Z) effectively retain lubrication and exclude large particulate contaminants, contributing to a long service life without re-lubrication. The presence of the snap ring groove (NR) significantly enhances assembly efficiency and provides secure axial positioning, increasing the overall rigidity of the mounting arrangement. Manufactured to ABEC 1 | ISO P0 tolerance class, it delivers reliable and consistent performance for a wide range of industrial applications.
