Product Introduction

UNS Series - Non-Standard Custom Ball Spline

UNS Series is UVT's non-standard ball spline program, covering custom dimensions and configurations beyond standard catalogs. UVT specializes in tailor-made ball splines - custom shaft diameters, strokes, flange interfaces, materials and surface treatments - for unique machine designs and upgrade projects.

Key features:

  • Custom shaft diameter, length and stroke per your design

  • Custom flange type and mounting interface

  • Special materials including stainless steel for clean-room use

  • Surface treatments: PVD, DLC, black oxide, anti-rust

  • Rapid prototyping with 2-3 weeks prototype delivery

Typical applications: equipment upgrades, space-constrained designs, high-cycle production machines and special environment applications (clean-room, corrosion, vacuum).

Send your drawings and working conditions - UVT engineers will confirm feasibility and lead time quickly.
