1205-TVH-C3 Bearing Product Overview & Core Advantages
The 1205-TVH-C3 is a double row angular contact ball bearing engineered for applications demanding high rigidity and reliable performance under combined loads. This metric bearing features an open design and is pre-lubricated for immediate use. Its compact dimensions (25mm bore, 52mm OD, 15mm width) and precision construction make it an ideal solution for arrangements requiring robust support and moderate limiting speeds up to 18,000 rpm. The C3 radial internal clearance ensures optimal performance in applications with elevated operational temperatures or where fit-up conditions generate higher internal loads.
Model Code Breakdown
- 1205: Basic bearing designation indicating a 25mm bore diameter and a light series.
- TVH: Denotes the cage material and type. The "TVH" suffix typically indicates a glass fiber reinforced polyamide (Nylon) cage, which contributes to lower friction, quieter operation, and is suitable for high-speed applications.
- C3: Specifies a radial internal clearance greater than the Normal (CN) group. This is selected for applications where thermal expansion or interference fits require additional internal operating space.
1205-TVH-C3 Bearing Structural Features & Performance Benefits
High Rigidity & Load Capacity: The double row ball complement and contact angle design provide significantly higher radial rigidity compared to single row bearings. This enables the bearing to effectively support substantial radial dynamic loads (3218 lbf) and moderate axial loads from both directions.
Optimized High-Speed Performance: The standard Nylon cage (TVH) ensures smooth operation at the specified limiting speed of 18,000 rpm. Its lightweight nature reduces centrifugal forces, minimizing friction and heat generation.
Pre-Lubricated for Longevity: The bearing comes lubricated from the factory, providing immediate protection and reducing initial maintenance. The specified temperature range of -30°C to 110°C ensures consistent performance across various operating environments.
Material Integrity: Manufactured from high-grade Chrome Steel for both rings and balls, the bearing offers excellent durability, wear resistance, and a long operational lifespan.
1205-TVH-C3 Bearing Typical Application Areas
The 1205-TVH-C3 is widely used in industrial machinery and equipment where compact design, high rigidity, and reliable performance are critical. Key application areas include:
- Electric Motors and small Gearboxes
- Pumps and Compressors
- Precision Spindles in light-duty machinery
