6306-2RS/C3 GJN

• 6306: Basic model number denoting a medium-duty, single row deep groove ball bearing with a 30mm bore.
• 2RS: Designates contact rubber seals on both sides. This provides superior protection against contaminants and retains lubricant effectively.
• C3: Indicates a greater than normal radial internal clearance. This is ideal for applications where thermal expansion of the shaft or housing is expected, preventing preload and potential binding.
• GJN: Specifies the use of a high-quality, lithium soap-based grease with a polyurea thickener. This lubrication offers excellent stability, water resistance, and a wide operating temperature range.

The performance of the 6306-2RS/C3 GJN is derived from its specific design features:

• Robust Sealing (2RS): The double-sided contact seals provide an effective barrier against dust, moisture, and other contaminants, significantly enhancing bearing life in harsh environments. They also securely retain the factory-applied grease.
• Optimized Internal Clearance (C3): The C3 clearance group allows for stable operation in applications with elevated temperatures or where fits result in a reduction of internal clearance, preventing performance issues due to thermal expansion.
• Precision and Quality: Manufactured to ABEC 1 | ISO P0 tolerance class, this bearing ensures consistent dimensional accuracy and smooth running characteristics for reliable performance in a wide range of equipment.
• Ready-to-Use Lubrication (GJN): The bearing is pre-lubricated with a high-performance grease, making it maintenance-free for its entire service life in many applications and ready for immediate installation.

The 6306-2RS/C3 GJN is versatile and commonly specified in various industrial sectors, including:

• Electric Motors and Generators
• Gearboxes and Power Transmission Systems
• Industrial Pumps and Compressors
• Material Handling Equipment (e.g., conveyor pulleys)
• Agricultural Machinery
• General Industrial Machinery requiring sealed and pre-lubricated bearings
