1215-K-TVH-C3 Bearing Product Overview & Core Advantages
The 1215-K-TVH-C3 is a double row angular contact ball bearing designed for demanding applications requiring high rigidity and precise operation. Featuring a metric taper bore (1:12), this bearing excels at handling combined radial and axial loads simultaneously. Its double row construction provides exceptional stability and load capacity in a compact design, making it ideal for high-precision machinery where reliability is paramount. The bearing comes pre-lubricated and features a C3 radial internal clearance, suitable for applications with thermal expansion or specific fit requirements.
1215-K-TVH-C3 Bearing Model Code Explained, Specifications & Naming Convention
The model number 1215-K-TVH-C3 provides detailed technical specifications:
- 1215: Basic bearing designation, indicating the series and size.
- K: Denotes a taper bore with a 1:12 ratio, designed for secure mounting on tapered shafts.
- TVH: Indicates the cage material is Nylon (Polyamide), which contributes to quiet operation, reduced friction, and is suitable for high-speed applications.
- C3: Specifies a greater radial internal clearance than the standard C0 group. This is beneficial for applications where thermal expansion of the shaft or housing is expected, or for specific interference fits, preventing excessive preload and potential seizure.
1215-K-TVH-C3 Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The double row ball bearing design provides significantly higher radial and axial rigidity compared to single row bearings. This allows it to effectively support combined loads and moments, ensuring stable operation under demanding conditions.
- Optimized for Performance: The Nylon (TVH) cage ensures smooth operation at high speeds with excellent acceleration characteristics and low noise. The open seal type allows for optimal re-lubrication and heat dissipation, extending service life in high-performance applications.
- Precision & Reliability: Manufactured from high-grade chrome steel for both rings and balls, the bearing offers high durability and fatigue resistance. The C3 clearance provides operational flexibility, accommodating thermal effects and preventing binding.
- High-Speed Capability: With a limiting speed of 6,700 rpm, this bearing is engineered for high-speed applications, a performance enhanced by the lightweight Nylon cage and effective lubrication.
1215-K-TVH-C3 Bearing Typical Application Areas
This bearing is ideally suited for industrial machinery requiring robust performance and precision, including:
- Electric Motors and Gearboxes
- Industrial Pumps and Compressors
- Material Handling Equipment
- Agricultural Machinery
- Construction Equipment
