Product Description
Bearing Screw Slotted Adjustment Screw Assembly
Product Overview
Bearing Slotted Adjustment Screw Assembly is a high-precision pre-assembled rotating hardware component specifically designed for mechanical fine adjustment, angle calibration, gap positioning, and movable assembly structures. This integrated component combines a slotted head adjustment screw with a precision miniature bearing into a single finished assembly, eliminating the need for secondary customer assembly.
The unique single-slot slotted head enables convenient manual or tool fine-tuning, while the built-in bearing ensures ultra-smooth 360° rotating operation without jamming, friction noise, or rigid abrasion. Unlike traditional fixed screws and ordinary adjustment fasteners, this bearing screw assembly provides both locking positioning and free rotating adjustment simultaneously, solving problems of difficult fine-tuning, easy wear, and inflexible movement in mechanical adjustable structures.
All units are precisely CNC machined with stable tolerance, smooth surface finish, and durable rotation performance. We provide comprehensive non-standard custom machining for screw size, bearing model, slot specification, and overall assembly structure to match diverse equipment adjustment requirements.
Core Features
- Integrated Pre-assembled Structure: Bearing and slotted adjustment screw are pre-assembled as a complete component, saving installation time, reducing assembly errors, and improving production efficiency.
- Slotted Head Fine Adjustment Design: Standard single-slot head structure supports flexible manual and tool adjustment, enabling accurate micro-positioning and angle fine-tuning for mechanical structures.
- Smooth Bearing Rotation Performance: Built-in high-precision miniature bearing enables free low-resistance rotation with no jamming, low noise, and no rigid friction during long-term repeated adjustments.
- Dual Functions of Locking & Adjustment: Provides stable fastening and flexible movable adjustment in one component, perfectly suited for adjustable mechanical positioning structures.
- Durable & Wear Resistant: Precision-machined screw thread and high-quality bearing material ensure long service life, stable rotation accuracy, and no loosening after frequent adjustments.
- Full Non-standard Customization: Custom screw specification, thread pitch, bearing size, slot width, and assembly appearance for personalized mechanical matching.
