3315 A-2Z Bearing Product Overview & Core Advantages
The 3315 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 bidirectional axial loads. Its compact design, featuring integral shields and pre-lubrication, makes it an ideal, long-lasting solution for high-reliability machinery where space is at a premium and maintenance access is limited.
3315 A-2Z Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 3315 | Standard bearing series designation, defining the core bearing dimensions (75mm bore, 160mm OD). |
| A | Denotes a specific internal design and contact angle optimized for angular contact performance. |
| 2Z | Signifies that the bearing is equipped with shields on both sides. This provides effective protection against contaminant ingress while being suitable for high-speed operation. |
3315 A-2Z Bearing Structural Features & Performance Benefits
High Rigidity & Load Capacity: The double row ball complement and robust construction provide exceptional rigidity, enabling stable support for shafts under heavy combined loads. This design is crucial for applications with complex force vectors.
Optimized for Performance: The stainless steel cage ensures low friction and reliable guidance of the balls, contributing to smooth operation and enhanced high-speed capability. The specified P6 (ABEC-3) tolerance class guarantees high running accuracy.
Maintenance-Free Operation: With shields on both sides (2Z) and factory-applied lubrication, the bearing is sealed against contaminants and is ready for long-term, maintenance-free service within its designated temperature range.
