· Product Overview
Introducing the YITECH Precision U-Frame Mounting Bracket — a high-rigidity, CNC-milled structural component engineered for optical benches, linear motion systems, sensor arrays, and modular automation chassis.
This bracket delivers:
- U-shaped profile (length 150 mm × height 25 mm × thickness 6 mm standard) for exceptional torsional stiffness
- Six precision-drilled through-holes (M3 standard, 25 mm spacing) for flexible, repeatable mounting
- Solid billet construction (A6061-T6 aluminum or 304 stainless steel) — zero warpage, ±0.01 mm dimensional control
- Mirror-finish milling (Ra ≤ 0.5 μm) — smooth surfaces, minimal vibration transmission
- Flatness tolerance ≤ 0.02 mm over full length — ensures optical/kinematic alignment
Unlike stamped or bent sheet-metal brackets, this part guarantees no spring-back, no residual stress, and no micro-cracks — making it ideal for applications requiring long-term dimensional stability under load or thermal cycling.
Perfect for engineers building compact, high-precision mechanical assemblies where rigidity = reliability.

· Application Scenarios
This U-bracket excels in high-precision structural and mounting roles:
- Optical Benches & Laser Systems
→ Rigid base for mirrors, lenses, or beam splitters
→ Flat top surface ensures collinear alignment (±0.02 mm flatness)
→ Holes allow modular attachment of posts, clamps, or kinematic mounts - Linear Motion & Stage Systems
→ Mounting plate for linear encoders, limit switches, or motor brackets
→ U-shape resists twisting during carriage movement - Robotics & Automation
→ Sensor array frame for LiDAR, cameras, or force sensors
→ Modular design enables rapid reconfiguration in field service - Medical Devices
→ Structural chassis for diagnostic imaging modules or surgical robots
→ Non-magnetic (Al) or biocompatible (304 SS) options available - Aerospace & Defense
→ Vibration-damped mounting for avionics or payload interfaces
→ Meets MIL-STD-810G shock/vibration specs (tested up to 20 g RMS)
💡 Why engineers choose this bracket:
- Solid billet = no spring-back — unlike bent sheet metal
- Flatness ≤ 0.02 mm = optical-grade reference surface
- 6-hole pattern = flexible mounting without redesign
- Customizable in days — not weeks like traditional fabrication
