6305-2Z/C3MT33 Bearing Product Overview & Core Advantages
The 6305-2Z/C3MT33 is a single row deep groove ball bearing engineered for high reliability in demanding applications. Its core advantage lies in its ability to efficiently handle radial loads while offering robust performance. The combination of shielded construction and a C3 radial internal clearance pre-lubricated with MT33 grease makes it a versatile, long-lasting, and low-maintenance solution, ideal for applications requiring consistent operation over a wide temperature range.
Model Code Breakdown
- 6305: Basic model number denoting a single row deep groove ball bearing with a 25mm bore and 62mm outside diameter.
- 2Z: Designates a non-contact steel shield on both sides. This provides effective protection against contaminant ingress while minimizing friction and heat generation.
- C3: Indicates a greater than normal radial internal clearance. This is beneficial for applications with thermal expansion, heavy loads, or where interference fits are used.
- MT33: Specifies a high-quality, lithium soap-based grease lubricant. It offers excellent performance across the bearing's specified temperature range (-30°C to 120°C), contributing to long service life and reduced maintenance.
6305-2Z/C3MT33 Bearing Structural Features & Performance Benefits
Robust Construction for High Load Capacity: Manufactured from chrome steel for both rings, balls, and cage, this bearing ensures high strength and durability. Its single row deep groove design is optimized to carry significant radial dynamic loads (4631 lbf) and moderate axial loads in both directions.
Optimized for Stable Operation: The C3 clearance provides operational stability in applications prone to thermal expansion, preventing pre-load and potential seizure, thereby enhancing reliability.
Sealed and Pre-Lubricated for Longevity: The 2Z shields effectively seal the bearing, protecting the MT33 grease and rolling elements from contamination. This sealed-for-life design eliminates the need for re-lubrication, making it a true maintenance-free component.
Precision and Speed: Built to ABEC 1 | ISO P0 tolerance standards, it ensures smooth running and is capable of operating at limiting speeds up to 11,000 rpm.
6305-2Z/C3MT33 Bearing Typical Application Areas
The 6305-2Z/C3MT33 is widely used across various industries due to its robust and maintenance-free characteristics. Key application areas include:
- Electric Motors and Gearboxes
- Industrial Pumps and Fans
- Material Handling Equipment (e.g., conveyor systems)
- Agricultural Machinery
- Automotive Components (e.g., alternators, idler pulleys)
