6002-ZTN9 Bearing Product Overview & Core Advantages
The 6002-ZTN9 is a single row deep groove ball bearing engineered for high-speed operation and reliable performance in demanding applications. Its compact design combines a 15 mm bore with a 32 mm outside diameter and a 9 mm width, offering an excellent balance between load capacity and space constraints. Manufactured to ABEC 1 | ISO P0 precision standards, this bearing is designed to handle primarily radial loads efficiently. A key feature is the combination of Z-type shields and a Nylon (TN9) cage, which contributes to its high rotational capabilities and durability, making it a robust choice for precision machinery.
6002-ZTN9 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning | Benefit |
|---|---|---|
| 6002 | Basic bearing designation indicating a metric, single row deep groove ball bearing with a 15 mm bore and 32 mm outside diameter. | Defines the standard dimensions and type. |
| -Z | Denotes a non-contact shield on one side of the bearing. | Protects against large contaminants with minimal impact on speed. |
| TN9 | Indicates a glass fiber reinforced Nylon (Polyamide) cage, pressed and centered on the balls. | Enables high-speed operation, offers good strength-to-weight ratio, and is compatible with many lubricants. |
6002-ZTN9 Bearing Structural Features & Performance Benefits
- Optimized for High Speeds: The lightweight TN9 Nylon cage reduces centrifugal forces and friction, directly contributing to the bearing's high limiting speed of 23,000 rpm. This makes it suitable for applications requiring rapid rotation.
- Effective Contamination Protection: The Z-type steel shield provides a robust barrier against large particulate contaminants, helping to extend the bearing's service life in moderately dirty environments.
- Precision and Reliability: Manufactured to ABEC 1 (ISO P0) tolerance class with a standard CN radial internal clearance, this bearing ensures consistent performance, low noise, and smooth operation.
- Robust Material Construction: Both the rings and balls are made from hardened Chrome Steel, providing high load capacity (Dynamic: 1259 lbf, Static: 641 lbf) and excellent wear resistance.
- Application Flexibility: The bearing is supplied without lubrication, allowing for the selection of a specialized grease or oil best suited for the specific operating temperature range of -30°C to 120°C.
6002-ZTN9 Bearing Typical Application Areas
The 6002-ZTN9 is ideally suited for a wide range of industrial and precision applications, including:
- Electric Motors and small spindles
- Office Automation Equipment (e.g., printers, scanners)
- Medical Devices and dental handpieces
- Ventilation Fans and blowers
- Power Tools and light machinery
