127-TVH Bearing Product Overview & Core Advantages
The 127-TVH is a double row angular contact ball bearing designed for applications requiring high rigidity and the ability to handle combined loads. Its compact bearing dimensions (7 mm bore, 22 mm OD, 7 mm width) make it ideal for space-constrained, high-precision assemblies. Manufactured from chrome steel and featuring a nylon cage, this precision bearing offers reliable performance and is pre-lubricated for immediate use, supporting a wide operating temperature range.
127-TVH Bearing Model Code Explained, Specifications & Naming Convention
| Suffix | Technical Meaning |
|---|---|
| TVH | Indicates a specific internal design and pre-lubrication for the bearing, optimized for its performance characteristics. |
| Open (Seal Type) | The bearing is an open design, allowing for potential re-lubrication and suitability for high-speed applications where seal friction is a concern. |
127-TVH Bearing Structural Features & Performance Benefits
High Rigidity & Load Capacity: The double row construction provides significantly greater radial and moment load capacity compared to single row bearings, making it exceptionally high rigid and suitable for applications with combined loads.
High-Speed Performance: The lightweight nylon cage ensures stable operation and contributes to the bearing's high limiting speed of 40,000 rpm, classifying it as a capable high-speed bearing.
Precision & Reliability: Manufactured to tight dimensional tolerances and featuring a standard CN radial internal clearance, this bearing ensures precise shaft positioning and smooth, low-vibration operation.
Ready-to-Use Convenience: The bearing is delivered pre-lubricated, enabling immediate installation and initial operation without the need for additional greasing.
127-TVH Bearing Typical Application Areas
- Precision spindles in small electric motors and dental handpieces
- High-speed automation equipment and robotics
- Office machinery such as printers and scanners
- Instrumentation and medical devices
- Pumps and gearboxes with compact design requirements
