129-TVH Bearing Product Overview & Core Advantages
The 129-TVH is a double row angular contact ball bearing designed for applications requiring robust support for combined loads. Its metric design features a compact cross-section, making it ideal for space-constrained, high-precision assemblies. This bearing is engineered to handle significant radial loads while accommodating axial loads in both directions, offering a reliable solution for demanding industrial environments. Its construction ensures high rigidity and stable operation, contributing to enhanced machine performance and longevity.
129-TVH Bearing Model Code Explained, Specifications & Naming Convention
| Suffix / Prefix | Technical Meaning |
|---|---|
| 129 | Basic bearing designation, defining the core bearing dimensions and series. |
| TVH | Indicates specific internal design and performance characteristics, including the use of a Nylon cage and standard radial internal clearance (CN). |
129-TVH Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The double row ball complement and optimized raceway geometry provide superior high rigidity, enabling the bearing to support substantial combined loads (radial and bidirectional axial loads) effectively.
- Optimized High-Speed Performance: The lightweight Nylon cage minimizes centrifugal forces, reduces friction, and contributes to a high limiting speed of 38,000 rpm, making it suitable for high-speed applications.
- Precision & Reliability: Manufactured from Chrome Steel for both rings and balls, this bearing ensures high durability and consistent performance. The precise bearing dimensions and tight tolerances guarantee accurate shaft positioning.
- Pre-Lubricated for Immediate Use: The bearing comes lubricated from the factory, facilitating easy installation and providing immediate protection, which is essential for reducing initial setup time.
129-TVH Bearing Typical Application Areas
This double row angular contact ball bearing is widely used in various precision machinery and industrial equipment, including:
- Small Electric Motors and Gearboxes
- Precision Spindles in Power Tools
- Pumps and Compressors
- Office Automation Equipment
- Medical and Dental Handpieces
