723C Bearing Product Overview & Core Advantages
The 723C is a metric miniature angular contact ball bearing engineered for applications demanding high precision and exceptional rotational accuracy. Its design is optimized to handle significant combined loads—simultaneously supporting radial forces and axial thrust in one direction. Available in both sealed and open variants, it offers flexibility for different operational environments. With a compact bearing size of 3mm bore and 10mm outside diameter, it is an ideal solution for space-constrained, high-performance mechanisms requiring reliable, long-lasting operation.
723C Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 7 | Series designation for angular contact ball bearings |
| 23 | Indicates specific internal geometry and load capacity within the series |
| C | Specifies a 15° contact angle, optimized for high-speed operation and axial load capacity |
Key Configurations: The bearing is offered with optional seals for contamination protection or in an open design for direct lubrication. It is Universal Matchable (SU), allowing bearings to be paired in a back-to-back (DB), face-to-face (DF), or tandem (DT) arrangement to support complex load cases.
723C Bearing Structural Features & Performance Benefits
- High Precision & Rigidity: Manufactured to ABEC P5/P4 tolerance classes, this bearing ensures minimal runout and vibration. The single-row design with a precise 15° contact angle provides high rigidity against combined loads.
- Superior Load Capacity: Engineered to handle substantial combined radial and axial loads. With a dynamic load rating of 146.12 lbf and a static load rating of 53.95 lbf, it delivers reliable performance in demanding conditions.
- Exceptional High-Speed Performance: Features a lightweight nylon or phenolic cage that reduces centrifugal forces, enabling ultra-high speeds up to 100,000 r/min with oil lubrication. This makes it a premier high-speed bearing.
- Material & Lubrication Versatility: Options for steel or ceramic balls allow for customization based on application needs for speed, stiffness, or corrosion resistance. The lubricated and sealed versions offer long-term, maintenance-free operation.
723C Bearing Typical Application Areas
The 723C miniature precision bearing is critical in applications where space is limited and performance is paramount. Its primary uses include:
- High-Speed Spindles in PCB drilling and milling machines
- Precision Instrumentation and optical encoders
- Small Motors and turbo-molecular pumps
- Medical Devices such as dental handpieces and surgical tools
- Aerospace Actuators and guidance systems
