Fixed Side AK Series Ball Screw Bracket

Fixed Side AK Series Ball Screw Bracket

The AK series is the smallest and lightest member of the Fixed Side Ball Screw Bracket family. It is specifically designed to provide high-rigidity fixed support for miniature ball screws with shaft diameters typically ≤12mm (such as 6mm, 8mm, 10mm). Despite its small size, it integrates angular contact bearings capable of withstanding bidirectional loads, ensuring precise positioning without backlash and with high responsiveness in applications such as miniature robotic arms, precision optical adjustment mechanisms, and miniature automation equipment.

Technology

The core challenge and advantage of the Fixed Side AK Series Ball Screw Bracket lies in "building rigidity within millimeters." It is the ultimate solution for miniaturization design requirements.

Performance Characteristics AK Series Fixed-End Support Units EK Series Fixed-End Mounts Standard BK Series Fixed-End Support Mounts.
Core Positioning Ultra-compact and ultra-lightweight, designed for miniature lead screws and extremely confined spaces. Compact and economical, designed for small to medium-sized lead screws and applications with limited space. Universal, standard design; the workhorse of industrial applications.
Dimensions and Weight Extremely compact and lightweight, with overall dimensions one order of magnitude smaller than the EK series. Compact, smaller than the BK series. Standard industrial dimensions.
Suitable Lead Screw Diameter Micro-sized (typically φ6–φ12 mm). Suitable for small to medium-sized lead screws (typically 12–25 mm in diameter). Suitable for small to large sizes (typically from 15 mm in diameter).
Bearing Configuration Micro angular contact bearings, available in single-row or special compact designs, with precision-set preload. Single-row or lightly preloaded angular contact bearings. Standard double-row angular contact bearings in a back-to-back configuration.
Structural Design Highly integrated, may utilise non-standard locking mechanisms (such as set screws) to save axial space. Integrated, compact design featuring standard lock nuts. Standard construction featuring a locking nut and lock washers.
Typical Applications Micro-robots, medical catheter equipment, fibre optic aligners, precision instruments. Desktop CNC machines, small automation modules, educational equipment. Suitable for general-purpose CNC machine tools, laser equipment and industrial robots.

Main Technical Parameters and Design
1. Miniaturization Engineering Challenges:
Precision miniature bearings:  Uses extremely small angular contact bearings, requiring extremely high manufacturing precision to provide sufficient rigidity in a small space.
Space optimization: The design often omits traditional external locking nuts, instead using set screws to directly lock the ball screw shaft on the side wall of the support base, or using ultra-thin nuts to save every millimeter of axial space.
Lightweight materials: The housing may use lightweight materials such as aluminum alloy to achieve maximum weight reduction while ensuring rigidity.

2. Functional Assurance:
Despite its compact structure, it provides reliable bidirectional axial positioning, serving as an absolute benchmark for miniature ball screw systems.
Features basic dustproof design, such as O-rings or miniature sealing lips, suitable for laboratory or clean environments.

3. Installation Characteristics:
The mounting flange is typically small and circular or square, with fine-pitch small-size screw holes, suitable for mounting on thin-walled or precision brackets.
Requires extremely high flatness and perpendicularity of the mounting surface, as small installation errors are magnified in miniature systems.

Applications
The Fixed Side AK Series Ball Screw Bracket is an indispensable core component in the following cutting-edge miniaturization fields:
Miniature robotics: Joint drive fixed ends for surgical robots, cell manipulation robots, and biomimetic miniature robots.
Precision optics and photonics: Precision displacement adjustment mechanisms inside fiber optic splicing machines, optical switches, and tunable lasers. Semiconductor and MEMS Packaging: Chip mounting equipment, micro-dispensing machine micro-positioning platforms.
High-end Instrumentation: Scanning probe microscopes, spectrometer slit adjustment mechanisms.

The Fixed Side AK Series Ball Screw Bracket is a milestone in the miniaturization of precision machinery. It proves that even when scaled down to the extreme, the pursuit of rigidity, precision, and reliability cannot be compromised. Choosing the AK series means you are challenging the size limits of mechanical design and injecting professional-grade, highly reliable "cornerstone" components into your miniature devices. It is not only a support base for miniature ball screws but also the key to unlocking precise motion control in the microscopic world.
