1311-K-TVH-C3 Bearing Product Overview & Core Advantages
The 1311-K-TVH-C3 is a double row angular contact ball bearing designed for exceptional performance in demanding applications. This precision bearing features a tapered bore (1:12) and is pre-lubricated for immediate use. Its core advantages include the ability to accommodate significant combined loads (radial and axial) simultaneously, high operational reliability due to its double-row construction, and a generous C3 radial internal clearance suitable for applications with thermal expansion or heavy interference fits. The nylon cage contributes to smooth, high-speed operation, making it an ideal choice for robust and precise machinery.
1311-K-TVH-C3 Bearing Model Code Explained, Specifications & Naming Convention
| Suffix Code | Technical Meaning | Advantage |
|---|---|---|
| K | Tapered Bore (1:12) | Allows for precise axial adjustment and secure mounting on adapter sleeves or withdrawal sleeves. |
| TVH | Nylon Cage (Polyamide Cage), Lubricated | Enables quieter operation and higher limiting speeds compared to metal cages. The bearing is supplied pre-lubricated. |
| C3 | Radial Internal Clearance greater than Normal | Accommodates thermal expansion from high-speed operation or heavy interference fits, preventing premature failure. |
1311-K-TVH-C3 Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The double row ball construction provides superior rigidity and enables the bearing to support substantial radial loads and bidirectional axial loads simultaneously, handling combined loads effectively.
- Optimized High-Speed Performance: The lightweight nylon cage (TVH) reduces centrifugal forces, lowers friction, and allows for a higher limiting speed of 7,500 rpm, making it a capable high-speed bearing.
- Convenient Tapered Bore: The K designation indicates a tapered bore, which facilitates easier installation and disassembly on tapered shaft seats, ensuring a secure and precise fit.
- Ready-to-Use & Durable: The bearing is supplied lubricated and features an open design, which is suitable for environments where re-lubrication is part of the maintenance schedule, extending service life.
1311-K-TVH-C3 Bearing Typical Application Areas
