Precision rotary joint manufacturing since 2010. Made in Ningbo, delivered worldwide.
Begapunk is a specialized rotary joint (rotary union) manufacturer based in Ningbo, Zhejiang Province, China. We design and produce single-channel and multi-channel rotary joints for industrial automation, CNC machining, laser cutting, plastic extrusion, wind energy, and other rotating machinery applications.
Unlike general-purpose hydraulic component suppliers, we focus exclusively on rotary joints. This specialization allows us to offer deeper engineering support, faster custom prototyping, and more competitive pricing than multi-product competitors like Deublin or Kadant for equivalent specifications.
Our factory covers 3,200 square meters with 28 CNC machines, 6 seal testing stations, and a dedicated R&D lab. Every rotary joint undergoes 100% pressure testing at 1.5× rated pressure before shipment.
