1311-K-TVH Bearing Product Overview & Core Advantages
The 1311-K-TVH is a double row angular contact ball bearing designed for applications demanding high rigidity and the ability to handle combined loads. Featuring a tapered bore (1:12 ratio), this precision bearing is engineered to support significant radial loads while also accommodating axial loads in both directions. Its compact design and robust construction make it an ideal solution for high-reliability machinery where space constraints and performance are critical. The bearing is pre-lubricated and features a nylon cage, contributing to smooth operation and reduced maintenance needs.
Model Code Breakdown
| Code Segment | Technical Meaning |
|---|---|
| 1311 | Standard bore diameter code (55 mm) and series designation. |
| K | Indicates a tapered bore with a 1:12 ratio, designed for precise mounting on adapter sleeves or withdrawal sleeves. |
| TVH | Designates the cage type and material. "TVH" typically signifies a glass fiber reinforced polyamide (nylon) cage, which is lightweight and suitable for high-speed operation, contributing to lower friction and quieter running. |
1311-K-TVH Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The double row design provides superior rigidity and enables the bearing to support substantial radial loads (dynamic: 11408 lbf, static: 4050 lbf) and bidirectional axial loads simultaneously, making it ideal for applications with combined loads.
- Optimized for Precision Mounting: The tapered bore (1:12) allows for precise axial positioning and secure fitting onto a sleeve, ensuring minimal runout and optimal performance in high-precision assemblies.
- High-Speed Performance: The standard nylon cage (TVH) reduces centrifugal forces, lowers friction, and allows for a limiting speed of 7,500 rpm, making it a capable high-speed bearing.
- Ready-to-Use & Durable: The bearing is pre-lubricated and features an open design, facilitating initial setup. Manufactured from chrome steel for both rings and balls, it offers excellent durability and a wide operating temperature range from -30°C to 110°C.
1311-K-TVH Bearing Typical Application Areas
