6308-2RS1/C3LT20 Bearing Product Overview & Core Advantages
The 6308-2RS1/C3LT20 is a single row deep groove ball bearing engineered for high reliability and robust performance in demanding applications. Its core advantages stem from its sealed construction and optimized internal geometry, enabling it to efficiently handle significant radial loads while accommodating moderate axial loads in both directions. The combination of a C3 radial internal clearance and high-quality materials makes this bearing particularly suitable for applications with thermal expansion or where precise shaft alignment is critical, ensuring consistent operation and long service life.
Model Code In-Depth Analysis
- 6308: Basic model number indicating a metric, single row deep groove ball bearing with a 40mm bore, 90mm OD, and 23mm width.
- 2RS1: Designates contact seals on both sides. The "RS" indicates nitrile rubber (NBR) seals, providing superior protection against contaminants and moisture retention compared to non-contact shields.
- C3: Specifies a greater than normal radial internal clearance. This is essential for applications involving thermal expansion, high speeds, or where fits result in a reduction of internal clearance.
- LT20: Indicates the bearing is pre-lubricated with a specific high-quality lithium-based grease, suitable for the specified temperature range and offering long-term lubrication.
6308-2RS1/C3LT20 Bearing Structural Features & Performance Benefits
Sealed & Protected Design: The 2RS1 double-contact seals effectively exclude contaminants like dust and dirt while retaining lubricant. This results in a maintenance-free and long-lasting bearing solution, reducing downtime and total cost of ownership.
Optimized Internal Clearance: The C3 clearance group provides operational stability in environments with elevated temperatures or where interference fits are used, preventing premature failure due to excessive preload and ensuring smooth running.
Robust Load Capacity: Manufactured from chrome steel for both rings and balls, this bearing offers a high dynamic and static load rating, providing durability and reliability under significant radial stresses.
Pre-Lubricated for Immediate Use: Filled with LT20 grease, the bearing is ready for installation and operation, simplifying the assembly process and ensuring optimal performance from the start.
