723AC Bearing Product Overview & Core Advantages
The 723AC is a double row angular contact ball bearing engineered for applications requiring exceptional precision and reliability. This high-precision bearing is designed to accommodate combined loads—simultaneously handling significant radial loads and axial loads in both directions. Its compact design, with a 3 mm bore, 10 mm outside diameter, and 4 mm width, makes it ideal for space-constrained, high-performance assemblies. Available in both sealed and open variants, and with options for preload, it delivers superior running accuracy and high rigidity.
723AC Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 723 | Basic bearing series designation, indicating a double row angular contact ball bearing with specific internal geometry. |
| AC | Angular Contact design, optimized for combined loads with a defined contact angle. |
Key Configurable Options: The 723AC base model can be specified with various suffixes to meet application needs:
- Seal Type: Available in sealed (for contaminant exclusion) or open (for custom lubrication schemes) designs.
- Preload: Available to eliminate internal clearance, enhancing system rigidity and rotational accuracy.
- ABEC Rating: Offered in high-precision P5 (ABEC-5) and ultra-precision P4 (ABEC-15) grades.
- Cage Material: Options include Nylon for quiet operation and high speeds, or Phenolic for robust performance.
- Ball Material: Standard Steel or high-performance Ceramic for specialized applications.
723AC Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The double row design provides superior radial and axial stiffness, enabling stable support under combined loads. The standardized 25° contact angle is optimized for sustaining substantial axial forces from both directions.
- Precision & High-Speed Performance: Manufactured to ABEC P5/P4 tolerance classes, this precision bearing ensures minimal runout and vibration. The lightweight Nylon cage option contributes to lower centrifugal forces, facilitating higher limiting speeds and quieter operation.
- Versatility & Longevity: The bearing is Universal Matchable (SU), allowing two bearings to be mounted in a tandem arrangement for increased load capacity. The availability of sealed and lubricated versions provides long-term, maintenance-free operation in demanding environments.
