217-2ZJ Bearing Product Overview & Core Advantages
The 217-2ZJ is a metric single row deep groove ball bearing engineered for robust performance in demanding industrial applications. Its primary advantage lies in its ability to efficiently handle radial loads while offering reliable operation. The bearing features shielded construction on both sides, providing effective protection against contaminant ingress without significantly increasing rotational torque. Manufactured to ABEC 1 | ISO P0 tolerance standards, it delivers consistent and precise performance, making it a cost-effective and reliable choice for a wide range of machinery.
217-2ZJ Bearing Model Code Explained, Specifications & Naming Convention
| Model Segment | Code | Technical Meaning |
|---|---|---|
| Basic Designation | 217 | Indicates the standard bearing size with a 85mm bore, 150mm OD, and 28mm width. |
| Seal/Shield Type | 2Z | Signifies shielded on both sides. The non-contact steel shields retain lubricant and protect against large particulate contaminants. |
| Internal Clearance | J | Corresponds to the CN group of radial internal clearance, which is the standard normal clearance for general applications. |
217-2ZJ Bearing Structural Features & Performance Benefits
- Robust Construction & High Load Capacity: Built entirely from chrome steel (rings, balls, and cage), this bearing offers high strength and durability. With a radial dynamic load rating of 21,762 lbf and a static load rating of 22,481 lbf, it is designed to withstand significant radial loads in continuous operation.
- Shielded for Contamination Protection: The 2Z designation indicates non-contact steel shields on both sides. This design offers superior protection against dust and debris compared to open bearings, extending service life in contaminated environments without the high friction associated with contact seals.
- Precision for Reliable Operation: Manufactured to ABEC 1 | ISO P0 tolerance class, this bearing ensures smooth and quiet running, contributing to the overall efficiency and reliability of the assembly.
- Versatile Operating Range: The bearing is suitable for a temperature range from -30°C to 120°C, accommodating a wide spectrum of industrial operating conditions.
217-2ZJ Bearing Typical Application Areas
The 217-2ZJ is a versatile component ideal for various industrial sectors requiring reliable radial load support and contamination protection. Common applications include:
- Electric Motors and Generators
- Industrial Gearboxes
- Material Handling Equipment (Conveyors, Pulleys)
- Agricultural Machinery
- General Industrial Machinery
