Floated Side AF Series Ball Screw Bracket

Main Technical Parameters and Design
1. Miniaturized Integrated Design:
Uses ultra-small deep groove ball bearings to ensure smooth axial floating at the micron level.
The structure is highly integrated, usually omitting external locking components, relying on the precision fit (micro-gap) between the bearing and the shaft to achieve the floating function, and may use elastic retaining rings or circlips for axial limiting.
The housing is made of aluminum alloy or high-strength engineering plastic to minimize weight.

2. Core Function Implementation:
The core of its design is to provide radial support without generating any additional axial constraint force, ensuring that the miniature screw can freely expand and contract when the temperature rises or under load, preventing system jamming or stress.

3. Precision Installation Requirements:
The mounting flange is a miniature design, fixed with M2 or M2.5 screws.
Due to the miniaturization of the system, the flatness, parallelism of the mounting surface, and the alignment accuracy with the screw axis are extremely demanding; even small deviations can lead to rough operation or additional wear.

Applications
The AF and AK series are the golden combination for the following micro-precision fields:
Miniature medical robots: Support for joints or feeding mechanisms in vascular surgery robots and microsurgical equipment.
Precision optics and communication: Internal optical path calibration of tunable lasers, optical switch arrays, and micro-displacement support for fiber optic docking platforms.
Bioengineering and scientific research: Precision moving parts for cell injectors, gene sequencers, and scanning ion conductance microscopes.
High-end consumer electronics: Miniature optical zoom and focusing modules in AR/VR devices. The Floated Side AF Series Ball Screw Bracket is a perfect embodiment of the "combination of rigidity and flexibility" concept in precision engineering at the micro-scale. It demonstrates that even in almost invisible spaces, the fundamental safeguards for motion reliability—support and thermal compensation—remain crucial and must be implemented with precision. Choosing the AF series means your miniature device design takes into account the most subtle thermodynamic effects, laying the foundation for ultimate stability and reliability.
