308 TN9/C3

The model number 308 TN9/C3 provides specific technical information:

• 308: Standard bearing designation indicating a metric series with a 40mm bore, 90mm OD, and 23mm width.
• TN9: Denotes the cage material, which is Nylon. This polymer cage contributes to lower friction, quieter operation, and is suitable for high-speed applications.
• C3: Specifies the radial internal clearance which is greater than normal (CN). This is optimal for applications with higher operational temperatures or where fits cause a reduction in internal clearance.

Note: The bearing features an Open (unsealed) design and comes with No Lubrication, allowing for custom lubrication strategies based on the specific application environment.

The 308 TN9/C3 leverages its design for superior performance:

• High-Speed Capability: The lightweight and durable Nylon (TN9) cage minimizes centrifugal forces and friction, enabling stable operation at the high limiting speed of 8,500 rpm.
• Robust Load Capacity: Constructed from hardened Chrome Steel for both rings and balls, this bearing reliably handles its high dynamic and static load ratings, providing a long operational lifespan under significant radial loads.
• Operational Flexibility: The C3 clearance accommodates thermal expansion, making it suitable for applications where shaft or housing fits are tight or operating temperatures are elevated.
• Precision Engineering: Manufactured to ABEC 1 | ISO P0 tolerance class, it ensures consistent running accuracy and smooth operation, which is critical for reducing vibration and noise.

This versatile single row ball bearing is ideally suited for a multitude of industrial sectors and equipment, including:

• Electric Motors and Generators
• Industrial Gearboxes
• Material Handling Conveyors
• Agricultural Machinery
• Pumps and Fans
