SKF 6309-2Z/C3 Deep Groove Ball Bearing
The SKF 6309-2Z/C3 is a robust and high-performance deep groove ball bearing that engineers primarily select for heavy-duty industrial applications. Firstly, this model belongs to the renowned SKF Explorer performance class. This designation ensures that the bearing provides higher load ratings and reduced friction, which leads to a significantly longer service life compared to standard options.
SKF 6309-2Z/C3 Technical Dimensions and Load Capacity
In addition to its durable construction, the SKF 6309-2Z/C3 features substantial and precise dimensions. It has a bore diameter of 45 mm, an outside diameter of 100 mm, and a width of 25 mm. Regarding its strength, the bearing offers a powerful basic dynamic load rating of 55.3 kN and a basic static load rating of 31.5 kN. Furthermore, it supports a reference speed of 15,000 r/min and a limiting speed of 7,500 r/min. Therefore, this model serves as a perfect solution for large-scale machinery where high load capacity and speed remain critical factors.
Key Features and C3 Internal Clearance
Specifically, the C3 radial internal clearance stands out as one of the most vital features of this bearing. This extra internal space is essential because it allows the metal components to expand thermally during continuous, high-speed operation. Without this clearance, heat could cause the bearing to seize or fail prematurely. Moreover, the SKF 6309-2Z/C3 utilizes premium bearing steel and dual metal shields to protect the internal grease from dust and environmental contaminants.
Additionally, the “2Z” designation confirms that the bearing includes non-contact shields on both sides. These shields effectively maintain lubrication while keeping friction to a minimum. As a result, the design minimizes maintenance requirements and ensures your heavy machinery stays operational for longer durations without interruption.
Versatile Industrial Applications
Because of its high load ratings and durable design, the 6309-2Z/C3 appears in many demanding sectors. For example, industrial motors, large pumps, agricultural equipment, and conveyors frequently rely on this specific model. Finally, the shielded configuration supports smooth movement and provides excellent reliability in harsh environments. This makes it a top-tier choice for maintenance managers who prioritize long-term performance and durability.
