6308-2Z/C3LHT30 Bearing Product Overview & Core Advantages
The 6308-2Z/C3LHT30 is a single row deep groove ball bearing designed for robust performance and long service life. Its key advantage lies in its ability to efficiently handle radial loads while offering operational stability. This bearing features integral shields (2Z) for contaminant protection and is supplied with a high-temperature grease (LHT30), making it a pre-lubricated, low-maintenance solution. The C3 radial internal clearance makes it particularly suitable for applications with thermal expansion or where interference fits are used, ensuring reliable performance across a wide temperature range.
Model Code Breakdown
- 6308: Basic series designation, indicating a medium-duty, single row deep groove ball bearing with a 40mm bore and 90mm OD.
- 2Z: Denotes a bearing with shields on both sides. This provides effective protection against solid contaminants while allowing for higher rotational speeds compared to contact seals.
- C3: Specifies a greater than normal radial internal clearance. This is essential for applications involving elevated operating temperatures or tight shaft/housing fits to prevent preload and potential seizure.
- LHT30: Indicates the bearing is pre-lubricated with a high-temperature lithium complex grease. This grease is stable and provides effective lubrication within the specified temperature range of -30°C to 120°C.
6308-2Z/C3LHT30 Bearing Structural Features & Performance Benefits
Robust Construction: Manufactured from chrome steel for rings, balls, and cage, this bearing ensures high strength and durability under demanding conditions.
High-Speed Capability: The combination of a deep groove raceway, precision-ground components to ABEC 1 | ISO P0 tolerance, and non-contact shields enables a high limiting speed of 7,500 rpm.
Enhanced Load Capacity: With a dynamic load rating of 915 lbf and a static load rating of 5395 lbf, it is engineered to handle significant radial loads in continuous operation.
Maintenance-Free Operation: The pre-lubrication with LHT30 grease and the presence of integral shields create a sealed-for-life unit, reducing the need for re-lubrication and minimizing downtime.
6308-2Z/C3LHT30 Bearing Typical Application Areas
The 6308-2Z/C3LHT30 is widely used in various industrial sectors due to its reliability and versatility. Common applications include:
- Electric Motors and Gearboxes
- Industrial Pumps and Fans
- Material Handling Equipment (e.g., conveyor systems)
- Agricultural Machinery
- General machinery requiring a robust, pre-lubricated bearing with contaminant protection.
