135TN Bearing Product Overview & Core Advantages
The 135TN is a double row angular contact ball bearing designed for applications requiring high precision and compact design. This precision bearing excels at simultaneously handling combined loads, including significant radial loads and moderate bidirectional axial loads. Its double row construction provides enhanced rigidity and stability compared to single row alternatives, making it ideal for high-reliability applications where space is constrained. Manufactured with chrome steel rings and balls, it delivers consistent performance and durability.
135TN Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 135 | Standard bearing series designation, indicating specific bearing dimensions (5mm bore, 19mm OD, 6mm width). |
| TN | Indicates a Nylon (Polyamide) cage. This lightweight cage contributes to lower friction, smoother operation, and is suitable for higher speed applications. |
135TN Bearing Structural Features & Performance Benefits
- High Rigidity & Stability: The double row design provides superior radial and moment load support, significantly increasing system stiffness and reducing deflection under load.
- Combined Load Capacity: Engineered to support substantial radial loads in conjunction with acting axial loads from both directions, eliminating the need for complex bearing arrangements.
- Optimized High-Speed Performance: The lightweight Nylon (TN) cage reduces centrifugal forces, enabling a high limiting speed of 45,000 rpm and ensuring smooth, stable rotation.
- Precision & Reliability: Manufactured with tight dimensional tolerances and CN radial internal clearance, this bearing ensures precise shaft positioning and low vibration operation.
- Pre-Lubricated & Ready-to-Use: Comes pre-lubricated, facilitating immediate installation and initial operation, suitable for the specified temperature range of -30°C to 110°C.
135TN Bearing Typical Application Areas
This versatile double row ball bearing is ideally suited for a wide range of compact, high-speed machinery, including:
- Small precision spindles in medical devices and dental handpieces
- High-speed rotors in miniature motors and fans
- Guidance rollers in office automation equipment (e.g., printers, scanners)
- Instrumentation and precision mechanical drives
- Small pumps and gearboxes requiring robust combined load support
