| Code Segment | Technical Meaning |
|---|---|
| 7015 | Basic bearing series and size designation (75mm bore, 115mm OD, 40mm width). |
| C | Specifies a 15° contact angle, optimized for high axial load capacity. |
| D | Indicates the bearing is part of a duplex tandem (DT) matched set. |
| /P4A | Denotes a high-precision tolerance class with enhanced running accuracy requirements. |
| Open | Seal type: No integral seals or shields, designed for optimal lubrication control in complex systems. |
7015 CD/P4ADT Bearing Structural Features & Performance Benefits
- High Rigidity & Axial Load Capacity: The duplex tandem (DT) arrangement combines two bearings to significantly increase axial stiffness and load-carrying capacity in one direction, providing exceptional support for machine tool spindles.
- Precision Performance: Manufactured to P4A tolerance class with a 15° contact angle, this bearing ensures minimal runout and smooth, precise rotation at high speeds.
- High-Speed Capability: The lightweight phenolic resin cage minimizes centrifugal forces, contributing to a high limiting speed of 22,000 rpm and stable operation.
- Optimized Internal Geometry: Features 20 precision balls made of chrome steel for high dynamic load ratings (19,170 lbf dynamic, 22,050 lbf static) and long service life.
- Preload & Matched Set: Supplied as a preloaded, matched pair, eliminating internal clearance and ensuring immediate, precise performance upon installation.
7015 CD/P4ADT Bearing Typical Application Areas
- Machine Tool Spindles: High-speed milling, grinding, and turning centers.
- Precision Rotary Tables and Indexing Heads.
- High-Frequency Motor Spindles.
- Industrial Pumps and Compressors requiring high axial stiffness.
