6311-2RSJEM Bearing Product Overview & Core Advantages
The 6311-2RS JEM is a sealed single row deep groove ball bearing engineered for robust performance in demanding applications. This metric bearing is designed to primarily handle radial loads while also accommodating moderate axial loads in both directions. Its key advantages include a high load capacity, reliable operation across a wide temperature range, and long service life due to its integrated seals and high-quality chrome steel construction. The combination of a standardized CN clearance and ABEC 1 (ISO P0) tolerance makes it a versatile and cost-effective solution for a multitude of industrial machinery.
6311-2RSJEM Bearing Model Code Explained, Specifications & Naming Convention
- 6311: Standard designation for a single row deep groove ball bearing with a 55 mm bore, 120 mm OD, and 29 mm width.
- 2RS: Signifies the bearing is equipped with contact seals on both sides. These seals effectively protect against contamination and retain lubricant, enhancing reliability.
- JEM: Indicates the specific manufacturer's suffix, often relating to internal design optimizations or proprietary manufacturing standards for consistent quality.
6311-2RSJEM Bearing Structural Features & Performance Benefits
Robust Construction for High Load Capacity: Manufactured from high-grade chrome steel for both rings and balls, this bearing offers excellent resistance to wear and fatigue, supporting a high dynamic load rating of 16,096 lbf and a static load rating of 10,116 lbf.
Enhanced Contamination Protection: The 2RS double-contact seals are a critical feature, providing a high level of defense against dust, moisture, and other particulate contaminants. This makes the bearing suitable for harsh environments and contributes to its longevity.
Balanced Performance & Speed: With a limiting speed of 5,600 rpm and standard CN radial internal clearance, the bearing delivers stable and quiet operation under a wide range of operating conditions.
Precision and Interchangeability: Built to ABEC 1 (ISO P0) tolerance class, it ensures reliable performance and easy replacement in standard applications.
