3215 A-2Z Bearing Product Overview & Core Advantages
The 3215 A-2Z is a double row angular contact ball bearing engineered for applications requiring high rigidity and precise operation. This precision bearing is designed to accommodate combined loads—simultaneously handling significant radial loads and axial loads in both directions. Its compact design, featuring two rows of balls and a contact angle, provides exceptional rotational accuracy and stability, making it ideal for high-reliability machinery. The inclusion of shields and factory-applied lubrication ensures long-term performance with minimal maintenance.
3215 A-2Z Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 3215 | Standard bearing series designation, indicating the bearing dimensions (75mm bore, 130mm OD). |
| A | Denotes a specific contact angle of 30°, optimized for carrying substantial axial loads. |
| 2Z | Signifies bearings with shields on both sides. This provides effective protection against contaminants while allowing for higher speed operation compared to contact seals. |
3215 A-2Z Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The double row construction significantly increases the bearing's rigidity and its ability to support combined loads (radial and bidirectional axial loads). The 30° contact angle is specifically designed to handle high axial thrust.
- Precision & Speed: Manufactured to P6 (ABEC-3) tolerance class, this bearing ensures smooth, quiet, and precise operation. The stainless steel cage contributes to stability at the limiting speed of 4,500 rpm.
- Durability & Reliability: Components made from chrome steel offer high load ratings (21,510 lbf dynamic, 19,800 lbf static) and excellent wear resistance. The pre-lubrication and shielded design provide a long service life in a wide temperature range of -30°C to 110°C.
- Ease of Use: The bearings are lubricated for life from the factory, making them ready for immediate installation and requiring no relubrication, which simplifies maintenance schedules.
3215 A-2Z Bearing Typical Application Areas
This double row angular contact ball bearing is suited for demanding applications across various industries, including:
- Machine Tool Spindles
- Gearboxes and Transmissions
- Industrial Pumps and Compressors
- Precision Agricultural and Construction Equipment
- Material Handling Systems
