6011-2RS1/C3GJN Bearing Product Overview & Core Advantages
The 6011-2RS1/C3GJN is a single row deep groove ball bearing designed for robust performance in demanding applications. Its primary advantage lies in its ability to efficiently handle radial loads while offering a degree of axial load capacity in both directions. This bearing features integrated seals (2RS1) for superior contamination protection and is supplied with a high-quality grease pre-lubrication (GJN), ensuring long-term, maintenance-free operation. Manufactured to ABEC 1 precision with a C3 radial internal clearance, it provides reliable performance and high running accuracy for general industrial use.
Model Code Breakdown
- 6011: Basic model number denoting a metric, single row deep groove ball bearing with a 55mm bore, 90mm OD, and 18mm width.
- 2RS1: Designates contact seals made of Nitrile Rubber (NBR) on both sides of the bearing, offering effective protection against contaminants and grease retention.
- C3: Indicates a radial internal clearance greater than the Normal (CN) group. This is suitable for applications with interference fits or where operational heat generation causes expansion.
- GJN: Signifies that the bearing is pre-lubricated with a standard, high-quality lithium soap-based grease, suitable for the specified temperature range.
6011-2RS1/C3GJN Bearing Structural Features & Performance Benefits
Robust Construction: Manufactured from chrome steel for rings, balls, and cage, this bearing ensures high strength and durability under radial dynamic and static loads of 6362 lbf and 4766 lbf respectively.
Sealed and Pre-Lubricated Design: The 2RS1 contact seals effectively shield the internal components from dust and moisture while retaining lubricant. Combined with the GJN grease pre-lubrication, this design offers a long service life with minimal maintenance requirements.
Optimized Internal Clearance: The C3 clearance provides operational stability in applications involving press fits and moderate temperature increases, preventing excessive preload and ensuring smooth running.
Balanced Performance: With a limiting speed of 7,500 rpm and a wide operating temperature range (-30°C to 120°C), this bearing delivers versatile performance for a broad spectrum of industrial machinery.
6011-2RS1/C3GJN Bearing Typical Application Areas
The 6011-2RS1/C3GJN is ideally suited for a wide range of applications requiring reliable, sealed bearing solutions, including:
- Electric Motors and Gearboxes
- Industrial Pumps and Fans
- Material Handling Equipment (e.g., conveyor systems)
- Agricultural Machinery
