1209-K-TVH-C3 Bearing Product Overview & Core Advantages
The 1209-K-TVH-C3 is a double row angular contact ball bearing designed for demanding applications requiring high rigidity and precise operation. This metric bearing features a tapered bore (1:12) for secure shaft mounting and is pre-lubricated for immediate use. Its double row design enables it to support significant combined loads (radial and axial) simultaneously, making it an ideal choice for high-precision machinery where space is limited and operational reliability is critical. The specified C3 radial internal clearance makes it suitable for applications with thermal expansion or where interference fits are used.
1209-K-TVH-C3 Bearing Model Code Explained, Specifications & Naming Convention
The model number 1209-K-TVH-C3 provides detailed technical specifications. Below is a breakdown:
- 1209: Basic designation indicating a double row angular contact ball bearing with a 45mm bore and 85mm outside diameter.
- K: Denotes a tapered bore with a 1:12 ratio, facilitating precise axial positioning and a secure fit on adapter sleeves or withdrawal sleeves.
- TVH: Signifies the cage material. "TV" typically indicates a glass fiber reinforced polyamide (Nylon) cage, and "H" may denote a specific design or treatment. This cage material contributes to lower friction, quieter operation, and is suitable for high-speed applications.
- C3: Indicates a greater radial internal clearance than the standard C0 group. This is essential for applications involving thermal expansion, heavy interference fits, or where operational temperatures fluctuate.
1209-K-TVH-C3 Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The double row ball bearing construction provides superior rigidity and can accommodate substantial radial loads and bidirectional axial loads, ensuring stable performance under combined loading conditions.
- Optimized for Precision: Manufactured from chrome steel for both rings and balls, the bearing offers high durability and consistent performance. The tight dimensional tolerances on the bore, outside diameter, and width guarantee precise shaft and housing fits.
- High-Speed Capability: The lightweight Nylon cage (TVH) reduces centrifugal forces, enabling higher limiting speeds (up to 11,000 rpm) and smoother operation with less vibration and noise.
- Pre-Lubricated & Ready-to-Use: The bearing comes pre-lubricated, simplifying installation and providing immediate protection against wear during the initial run-in period.
1209-K-TVH-C3 Bearing Typical Application Areas
This bearing is engineered for high-performance applications across various industries, including:
- Electric Motors and Gearboxes
- Industrial Pumps and Compressors
- Material Handling Equipment
- Agricultural Machinery
- Precision Spindles in various machinery
