UVT Precision Transmission
Ball spline manufacturing and OEM engineering support in Dongguan — from Ø3 mm miniature shafts to complete placement-head modules.
Focused on Ball Splines
Based in Dongguan, Guangdong, UVT designs, grinds and assembles ball splines for automation equipment makers in semiconductor, electronics, robotics and medical industries.
Our engineering team works directly with design engineers and buyers to replace imported splines, qualify a second source, and build non-standard parts from drawings.
Precision Grinding
Spline grooves ground in-house to micron level.
Inspection
Confirm dimensional inspection scope and request test conditions.
ISO 9001
Certified quality management system (QES 2025). Certificate available on request.
7–15 Days
Sample target for fewer than 10 sets; confirmed at quotation.
Manufacturing Capabilities
Groove grinding, nut assembly and dimensional inspection under one roof.
Ask us about capacity and process records for your project.
Define Acceptance Before Production
Request current quality certification, model-specific dimensions, preload and accuracy criteria. Agree sample tests and shipment inspection records.
Life test results are internal tests under stated conditions, not a universal service-life guarantee.
Selection Through Qualification
UVT reviews original model codes, machine requirements, drawings and custom machining.
Final specifications, compatibility and delivery are confirmed in the approved drawing and quotation.
- New equipment
- Review travel, loads and installation.
- Second source
- Compare the original model and mating dimensions.
- Custom assembly
- Confirm drawings, interfaces and acceptance tests.
