What we publish, and how we verify it

• All load ratings, life figures and specifications on this site come from working-condition testing by UVT's engineering team, not from marketing estimates.
• Example evidence: mounter endurance test - vertical shaft, 860 mm/s, 10 G, 15 mm stroke, total 200 million reciprocations (equivalent to more than 5 years of typical mounter operation); up to 500 million cycles under severe conditions for the 4 mm non-standard spline.
• Life is always evaluated with your duty cycle (load, speed, acceleration, stroke, frequency). Send us your working conditions and we provide life calculation support.

Company facts (verifiable)

• Brand: UVT (YouRuTe Transmission), a Chinese national brand for precision motion components.
• Industry position: one of only two manufacturers worldwide producing a stable 3 mm ultra-precision miniature ball spline (3 mm shaft, 7 mm outer sleeve), breaking a long-term foreign technology lock.
• Product range: ball splines, spline shafts, rotary ball splines, ball screw splines and planetary roller screws; shaft diameter 2-100 mm; precision grades (standard / H / P); preload classes (T0 clearance / T1 light preload).
• Applications: semiconductor packaging, IC test equipment, SMT mounters, AI component inserters, medical devices, aerospace and robotics.
• Customization: non-standard shaft diameter, stroke, flange interfaces, stainless steel shafts and surface treatments (PVD, DLC, black oxide) with prototype delivery in 2-3 weeks.
