Applications & Uses
The 723AC is a go-to bearing for engineers working in industries where space is constrained but performance cannot be compromised. Its ability to handle combined radial and axial loads at high speeds makes it indispensable in:
Machine Tool SpindlesOne of the most common applications for the 723AC is in precision machine tool spindles, including CNC grinding spindles and milling head assemblies. Its high rigidity and precision grade options (P4/P5) ensure tight dimensional accuracy and low vibration at elevated RPMs.
Ball Screw Support UnitsIn linear motion systems, ball screws require axial constraint at both ends. The 723AC, when used in DB or DF paired configurations, provides the bidirectional axial stability and preload characteristics needed to maintain positioning accuracy in CNC machines, robotics, and automation systems.
Dental and Medical EquipmentThe miniature form factor and smooth, low-noise operation make this bearing well suited for dental handpieces, surgical instruments, and compact medical devices where hygiene, precision, and quiet running are paramount.
Robotics and AutomationSmall robotic joints, end-effectors, and servo-driven axes frequently require bearings that can handle both radial and thrust loads within a tight space. The 723AC fits these assemblies without adding bulk.
Optical and Measurement InstrumentsHigh-precision instruments such as coordinate measuring machines (CMMs), optical encoders, and spectrometers rely on bearings that introduce minimal runout and vibration. The 723AC in P4 or P5 precision class serves this requirement effectively.
Pumps and CompressorsMiniature pump impeller shafts and micro-compressors benefit from the 723AC’s ability to manage combined loads in compact assemblies, especially in vertical shaft configurations where axial load management is critical.
Textile MachineryHigh-speed spindles in textile and yarn production require reliable miniature bearings that run smoothly over extended periods. The 723AC is frequently deployed here for its durability and speed capability.
Electronics and Semiconductor EquipmentPrecision actuators and positioning stages used in semiconductor fabrication, PCB assembly, and wafer handling equipment require ultra-precise, low-friction bearings — a category the 723AC satisfies.
Mounting Configurations Explained
The 723AC can be installed in several pairing arrangements depending on load direction and rigidity requirements:
- Single (Standalone): Used where only one-direction axial load is present and radial loads are moderate.
- DB – Back-to-Back: Contact angle lines diverge outward. Provides high rigidity and resistance to overturning moments. Best for bidirectional axial loads.
- DF – Face-to-Face: Contact angle lines converge inward. More suitable when shaft misalignment or deflection is a concern.
- DT – Tandem: Both bearings carry axial load in the same direction. Used when axial loads are particularly heavy in one direction.

Delivery Methods
NPBS ships globally and offers three primary modes of delivery to suit different urgency levels and budget considerations. Our logistics team helps you choose the most appropriate option at the time of order.
By Air
Air freight is the fastest option and is recommended when:
- You need urgent or emergency replacement of critical bearings
- Your order quantity is small and time-sensitive
- Project timelines are tight and delays are costly
We work with established air freight forwarders and can ship from major Indian cargo hubs directly to airports near your facility worldwide. Transit times typically range from 2 to 7 business days depending on the destination. Air shipments include full tracking from dispatch to delivery. Courier services (DHL, FedEx, UPS) are also available for smaller parcels requiring door-to-door delivery.
By Sea
Sea freight is the most economical option for bulk orders and is recommended when:
- You are placing a large order or stocking up inventory
- Lead time flexibility allows for longer transit
- You are sourcing for planned production requirements rather than urgent replacement
NPBS arranges sea freight via FCL (Full Container Load) or LCL (Less than Container Load) shipments through trusted freight forwarders. We handle export documentation, bill of lading coordination, and can arrange CIF, FOB, or EXW terms as per your trade agreement. Transit times vary by destination — typically 15 to 45 days — and we provide regular shipping updates throughout.
By Land / Road
Land transport is available for customers located within India and for regional cross-border shipments to neighboring countries. This mode is suitable when:
- Your facility is within overland reach from our dispatch point
- You require consolidated shipments alongside other goods
- Cost efficiency is a priority for regional deliveries
We partner with reliable road freight carriers offering door-to-door delivery with tracking. For domestic Indian deliveries, transit typically takes 2 to 7 business days depending on the destination state. For cross-border overland shipments, timelines are shared at the time of quotation based on routing.
Storage and Handling Recommendations
To ensure the 723AC retains its precision and performance upon arrival at your facility:
- Store bearings in their original packaging in a clean, dry environment away from direct sunlight and magnetic fields.
- Recommended storage temperature: 0°C to 25°C, relative humidity below 65%.
- Do not stack heavy items on bearing boxes.
- During installation, use appropriate tools — never apply force directly to the rolling elements. Press forces should be applied to the ring being fitted (inner ring for shaft fitting, outer ring for housing fitting).
- Use clean, lint-free gloves when handling precision-grade bearings to avoid contamination.
