The 71826 C P4A GA belongs to the elite 718 series of angular contact ball bearings. With its 18mm width, 130mm inner diameter, and 165mm outer diameter, it’s compact yet highly capable, making it the bearing of choice for:
High-speed CNC spindles
Electric motor spindles
Precision grinding machines
Robotic systems
It supports various mounting configurations including DB (back-to-back), DT (tandem), TBT (triplex tandem), and QBC (quad arrangement) to adapt to load and rigidity requirements across applications.
Bearing No. | d (mm) | D (mm) | B (mm) | Cr (kN) | Cor (kN) | Grease Speed (RPM) | Oil Speed (RPM) | Ceramic Ball Speed (RPM) | Preload (N) A / B / C |
---|---|---|---|---|---|---|---|---|---|
71826 C P4A GA | 130 | 165 | 18 | 42.50 | 51.00 | 7000 | 11000 | 9000 / 15000 | 208 / 723 / 1523 |
71826 AC | 130 | 165 | 18 | 40.00 | 48.00 | 6300 | 9500 | 7500 / 12000 | 277 / 1092 / 2378 |
Note: Contact angle “C” (15°) is standard, enabling high-speed capability with moderate axial load handling. Other angle options such as AC (25°) are available for higher axial load conditions.
What sets this bearing apart is its use of imported G5-grade steel balls and Kluberspeed NBU15 grease, ensuring:
Low vibration and noise
Excellent temperature stability
Minimal internal friction
Extended service life
The P4A precision grade offers ultra-fine tolerances, enabling these bearings to maintain consistent performance in high-speed applications where micro-deviation can cause major issues.
Whether operating as a single bearing or in matched arrangements, the 71826 C P4A GA can be configured for optimized rigidity, load sharing, and thermal expansion compensation. The flexibility in matching methods (DB, DT, TBT, QBC) makes it suitable for:
Horizontal or vertical spindle orientations
Precision tool holders
Dynamic load environments
This bearing is ideally suited for high-end applications in:
CNC machining centers
Aerospace part manufacturing
Electric vehicle (EV) motor spindles
Medical equipment requiring ultra-precise motion control
With high dynamic and static load ratings and exceptional speed capability, it serves as a backbone component in advanced manufacturing systems.
As demand grows for faster, more accurate, and energy-efficient machinery, the 71826 C P4A GA Angular Contact Ball Bearing is poised to become a go-to choice for OEMs and machine builders worldwide. Its unmatched combination of precision, speed, and rigidity makes it a foundational component in the era of Industry 4.0 and intelligent machining.
