6209-2Z/C3HT

• 6209: Basic model number for a single row deep groove ball bearing with a 45mm bore and 85mm outside diameter.
• 2Z: Designates that the bearing is shielded on both sides. The non-contact shields protect the internal components from large particulate contaminants while minimizing friction.
• C3: Indicates a greater than normal radial internal clearance. This is essential for applications involving high operational temperatures, heavy interference fits, or where thermal expansion differences between the shaft and housing occur.

The performance of the 6209-2Z/C3 is derived from its precise construction. The deep groove raceway and high-quality Chrome Steel construction for rings, balls, and cage provide a robust platform for handling significant radial dynamic loads up to 7351 lbf. The ABEC 1 | ISO P0 tolerance class ensures consistent and smooth operation. The C3 clearance is a critical feature, preventing pre-loading and potential seizure in thermally challenging environments. While the 2Z shields retain the factory-fresh internal environment, they do not constitute a sealed unit; the bearing is supplied without lubrication, allowing for custom greasing to suit specific application needs. This results in a versatile bearing with high limiting speed capabilities and adaptability.

This bearing is widely used across various industries due to its robust design and flexible internal clearance. Common applications include:

• Electric Motors and Generators
• Industrial Gearboxes and Power Transmission Systems
• Agricultural Machinery
• Material Handling Equipment such as conveyor pulleys
• Vibrating Screens and other machinery with thermal expansion considerations
