Exceptional Running Accuracy and Precision
Super precision angular contact ball bearings meet extreme tolerances (P4, P2, ABEC 7/9) for outstanding running accuracy, minimizing runout.
Buyers needing ultimate positioning accuracy and smooth operation in critical applications like machine tool spindles or measuring instruments rely on this precision bearing performance.
It ensures better workpiece quality and process reliability, and the precise performance is necessary for high-end machinery. Choose precision for superior results.
Designed for High Combined Loads
The specific contact angle in these angular contact bearings allows them to accommodate both radial and axial loads at the same time, primarily in one direction.
This makes super precision angular contact ball bearings the ideal choice for applications where axial loads are significant alongside radial forces.
Choosing the correct contact angle (e.g., 15°, 25°) is crucial for optimising load capacity and bearing life, ensuring your equipment performs reliably under its specific operating conditions.
Superior High-Speed Performance
Engineered with optimised internal geometry, quality materials, and superior manufacturing, these high precision ball bearings excel at high rotational speeds. Reduced friction and heat allow machinery to operate faster and more efficiently.
For high-RPM applications like high-speed spindle or turbo machine, invest in super precision angular contact ball bearings for the necessary capability and durability. Boost your productivity with bearings designed for speed and endurance.
FREQUENTLY ASKED QUESTIONS
What specifically qualifies a bearing as "Super Precision"?
It refers to meeting stringent international standards (like ISO Class 4/2, ABEC 7/9) for dimensional and running accuracy, significantly tighter than standard bearings. This ensures higher performance capabilities for demanding applications.
What does the contact angle (e.g., 15°, 25°) tell me when purchasing?
The contact angle indicates the bearing's relative capacity for axial vs. radial loads. A larger angle (like 25°) offers higher axial load capacity but lower speed limits compared to a smaller angle (like 15°). Choose based on your primary load type.
What lubrication is recommended for these high precision bearings?
High-speed applications often use specialized oils delivered via oil-air or oil-mist systems. For lower speeds or simpler setups, specific high-quality greases designed for precision bearings are suitable. Consult product details or contact us for recommendations.
