6311-2RS1/GJN Bearing Product Overview & Core Advantages
The 6311-2RS1/GJN is a metric single row deep groove ball bearing designed for superior performance in demanding applications. Its key advantages include the ability to handle significant radial loads and moderate axial loads in both directions. The bearing features integrated seals (2RS1) for effective contamination protection and is pre-lubricated with a high-quality synthetic hydrocarbon grease (GJN), ensuring long-term, maintenance-free operation. Manufactured to ABEC 1 | ISO P0 tolerance standards, it offers reliable precision and is ideal for applications requiring high reliability and durability.
Model Code Breakdown
- 6311: Basic model number denoting a metric single row deep groove ball bearing with a 55 mm bore, 120 mm OD, and 29 mm width.
- 2RS1: Signifies that the bearing is equipped with two contact seals (one on each side), providing excellent protection against contaminants and moisture ingress.
- GJN: Indicates the bearing is pre-lubricated with a specific synthetic hydrocarbon grease, suitable for a wide temperature range from -30°C to 120°C.
6311-2RS1/GJN Bearing Structural Features & Performance Benefits
The single row deep groove construction, combined with chrome steel rings, balls, and cage, provides a robust and durable solution. This design ensures high radial dynamic load capacity of 16,096 lbf and a radial static load capacity of 10,116 lbf. The contact seals (2RS1) not only protect the internal components from contamination but also effectively retain the grease, contributing to the bearing's long service life and maintenance-free characteristics. The optimized internal geometry and standard CN clearance contribute to smooth operation and a limiting speed of 5,600 rpm, making it suitable for a wide range of industrial speeds.
6311-2RS1/GJN Bearing Typical Application Areas
This versatile bearing is widely used in various industrial sectors, including:
- Electric Motors and Generators
- Industrial Gearboxes and Transmissions
- Material Handling Equipment such as Conveyors
- Agricultural Machinery
- General Industrial Machinery requiring reliable radial load support
