Founded as SYZ Bearing Co., Ltd — the origin of today’s SYZ Machine Co., Ltd and the beginning of our journey in motion technology and industrial bearings innovation.
Our Shanghai facility specialized in producing 3-piece aluminum rod ends and bronze race rod ends. Located in Shanghai, logistics were convenient and the business expanded rapidly.
Moved rod ends factory to Jiangsu Province (1.5h drive from Shanghai) to scale up. Spans 35,000 m², equipped with 19 CNCs, 12 lathes, grinding, threading, and mold injection machines.
Alex Wang took over. Renamed to SYZ Machine Co., Ltd to reflect broader manufacturing capabilities — moving beyond rod ends to custom machined parts for agricultural and industrial applications.
Attended our first international SEMA Show. Showcased hundreds of in-house manufactured suspension components — including rod ends, spherical plain bearings, and ball joints.
Attended the Performance Racing Industry (PRI) Show, launching new lines of metric rod ends, rebuildable joints, and stainless steel rod ends to racing aftermarket clients.
Expanded our multilingual sales and QC family. Exhibited at Automechanika Shanghai, welcoming customers globally to visit our headquarters and production facilities.
Showcased loader slot rod ends, COM-T spherical bearings, tie rod ends, misalignment spacers, tube adapters, rebuildable joints, and clevis mounts at SEMA.
Launched suspension control A-Arms featuring precision TIG welding at PRI, combining highly skilled craftsmanship with strict American quality standards.
Relocated our Shanghai office to the Jiurun Building. Houses our sales team, shipping/export clearancem QC, and warehouse for same-day shipping parts.
Established a new facility dedicated to manufacturing custom precision components beyond rod ends, accelerating prototype turnaround and reducing OEM costs.
A memorable year filled with training sessions, celebrations, joint trips, and company banquets, strengthening the cohesion behind every part we deliver.
Presented our full range of suspension components in Las Vegas, including clevis mounts, loader slot rod ends, and linkage adjusters, affirming our brand quality.
