6308-2ZTN9/C704HMTF8

• 6308: Standard designation for a single row deep groove ball bearing with a 40 mm bore and 90 mm outside diameter.
• 2Z: Indicates the bearing is shielded on both sides. This provides effective protection against contaminant ingress while minimizing friction, contributing to the high-speed performance.
• TN9: Specifies a glass fiber reinforced nylon cage. This cage material is lightweight, promotes smooth operation at high speeds, and offers good resistance to wear.
• C704HMTF8: This suffix combination indicates a specific radial internal clearance (CN) and the use of a high-performance synthetic grease suitable for the specified temperature range.

Optimized Load Handling: The deep groove raceway and single row ball construction are engineered to support significant radial dynamic load ratings (915 lbf), ensuring reliable performance under load.

High-Speed Capability: The lightweight nylon cage (TN9) reduces centrifugal forces, while the non-contact shields (2Z) minimize friction. This combination allows for a high limiting speed of 7,500 rpm.

Enhanced Durability and Low Maintenance: The double-shielded (2Z) design effectively seals in the factory-applied grease and seals out contaminants, resulting in a long service life with minimal maintenance requirements. The use of high-quality chrome steel for rings and balls ensures consistent performance and wear resistance.

Precision and Consistency: Manufactured to ABEC 1 | ISO P0 tolerance class, this bearing provides reliable running accuracy for a wide range of industrial applications.

This versatile bearing is ideally suited for a variety of sectors and machinery, including:

• Electric Motors and Generators
• Industrial Gearboxes
• Material Handling Equipment (e.g., conveyor systems)
• Agricultural Machinery
• Pumps and Fans
• General industrial machinery requiring a robust, high-speed radial bearing solution.
