7034 ACD/P4ATGA Bearing Product Overview & Core Advantages
The 7034 ACD/P4ATGA is a high-precision angular contact ball bearing designed for demanding applications requiring exceptional accuracy and reliability. Engineered to accommodate combined loads (simultaneous radial and axial loads), this bearing features a 25° contact angle for optimal axial load capacity. Manufactured to P4A tolerance class, it delivers superior running accuracy and rotational precision. Its universal matchable (SU) design allows for flexible mounting arrangements in sets, making it an ideal solution for high-rigidity and high-speed spindle systems.
7034 ACD/P4ATGA Bearing Model Code Explained, Specifications & Naming Convention
| Suffix Code | Technical Meaning | Performance Implication |
|---|---|---|
| ACD | Angular Contact, 25° Contact Angle | Optimized for handling significant axial loads in one direction |
| P4A | High Precision Tolerance Class | Superior dimensional and running accuracy for precision applications |
| TGA | Phenolic Cage Material | Enhanced high-speed performance with reduced friction and weight |
7034 ACD/P4ATGA Bearing Structural Features & Performance Benefits
High Rigidity & Load Capacity: The angular contact design with a 25° contact angle provides excellent resistance to combined loads, offering 98,100 lbf dynamic and 156,375 lbf static radial load ratings. This makes it suitable for applications with significant radial and axial force components.
Precision Engineering: Manufactured to P4A tolerance class with tight dimensional controls (bore and OD tolerance: -0.004mm to 0), ensuring minimal runout and vibration for superior operational accuracy.
High-Speed Capability: The phenolic cage (TGA) enables stable operation at high rotational speeds, with a limiting speed of 11,000 rpm. The cage's lightweight construction reduces centrifugal forces, contributing to enhanced high-speed performance.
Universal Matching: Designed as Universal Matchable (SU), these bearings can be arranged in pre-loaded sets of three without selective matching, simplifying installation and ensuring consistent preload performance in multi-bearing arrangements.
