Quality Control

At TranzBrillix, quality is the foundation of every linear motion component we deliver. From raw material selection to final inspection, all processes follow strict protocols to ensure precision, stability, and long service life across our full product range—linear guides, ball screws, splines, bearings, and related accessories.

TranzBrillix uses certified materials such as S55C rail steel, SNCM220 block steel, and high-grade bearing steel or stainless steel for miniature products. For ball screws, we select premium alloy steel with controlled composition to ensure hardness stability, fatigue resistance, and strong load capacity. All materials are fully traceable through internal quality systems.

CNC machining, precision grinding, and automated assembly lines operate under strict tolerances to guarantee parallelism, smooth running, consistency, and interchangeability with globally recognized brands.

TranzBrillix applies dedicated machining processes for each precision grade:

• C7 Rolled Ball Screws – optimized rolling profile plus precision turning
• C5 & C3 Ground Ball Screws – high-end thread grinding with controlled lead deviation
• End Machining – custom machining based on drawings (steps, keyways, threads, chamfers)
• Ball Nut Customization – non-standard nut housing design, preload adjustment, surface finishing

Every screw-nut assembly undergoes controlled torque testing and smoothness inspection before shipment

• Rail straightness & flatness measurement
• Block preload & smoothness testing
• Surface hardness & roughness verification

• Lead accuracy measurement
• Axial play / backlash inspection
• Hardness & heat-treatment depth testing
• Torque consistency check
• Vibration & smoothness running tests

• CMM dimensional measurement
• Laser alignment, micrometers, height gauges
• Heat-treatment depth and metallurgical analysis

TranzBrillix operates under ISO9001-based quality management, ensuring that linear guides and ball screws meet international tolerance levels and performance standards.

Our engineering and QC teams perform fatigue tests, evaluate application feedback, and continuously refine design details. Whether for guideways or ball screws, TranzBrillix is committed to delivering long-term reliability, stable performance, and consistent interchangeability.
