3214 A-2Z Bearing Product Overview & Core Advantages
The 3214 A-2Z is a double row angular contact ball bearing engineered for applications requiring high rigidity and the ability to handle combined loads. This precision bearing is designed to simultaneously support substantial radial loads and bidirectional axial loads, making it an ideal solution for compact, high-performance assemblies. Its shielded construction and factory-applied lubrication ensure long-term, maintenance-free operation, contributing to enhanced system reliability and reduced total cost of ownership.
Model Code Breakdown
| Code Segment | Technical Meaning |
|---|---|
| 3214 | Standard bore diameter (70 mm), outside diameter (125 mm), and width (39.7 mm) dimensions. |
| A | Denotes a specific contact angle optimized for supporting significant axial loads. |
| 2Z | Signifies bearings with shields on both sides. This provides effective protection against contaminant ingress while allowing for higher speed capabilities compared to contact seals. |
3214 A-2Z Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The double row design provides superior radial and axial stiffness, enabling the bearing to withstand demanding combined loads. The optimized contact angle ensures efficient handling of thrust loads from both directions.
- Optimized for Performance: Manufactured to P6 (ABEC-3) tolerance class, this bearing guarantees running accuracy and consistent performance. The stainless steel cage ensures stability and durability at the specified limiting speed of 4,500 rpm.
- Maintenance-Free Operation: The non-contact 2Z shields on both sides effectively retain the factory-applied lubricant and exclude contaminants. This pre-lubricated, shielded design provides long service life without the need for re-lubrication.
- Robust Material Construction: Components made from chrome steel (rings and balls) offer high load ratings and wear resistance, contributing to the bearing's radial dynamic load rating of 19,890 lbf and static capacity of 18,000 lbf.
3214 A-2Z Bearing Typical Application Areas
This bearing is ideally suited for a wide range of industrial machinery and precision equipment, including:
- Machine Tool Spindles
- Industrial Pumps and Compressors
- Gearboxes and Power Transmission Systems
- Precision Agricultural Machinery
- Material Handling Equipment
