Company founded
Suzhou Tiejin was established and the STT brand created.
About STT
Precision manufacturing,
built around miniature bearings.
Founded in 2012, STT develops and manufactures miniature precision bearings for demanding motion systems, combining product engineering, in-house equipment and disciplined quality control.
Focused expertise.
Industrial depth.
STT focuses on miniature and subminiature precision bearings. Its product capability covers precision deep-groove ball bearings, four-point-contact bearings, flex bearings and application-specific configurations.
From ring processing and heat treatment to precision grinding, clean assembly, vibration and noise inspection, critical processes are organised within one manufacturing system.
Development
milestones
STT has expanded from brand creation to scaled manufacturing, strengthening production capacity, headquarters infrastructure and access to the capital market.
Guozhao Road plant
A 10,000 m² manufacturing facility opened.
Yuexiu Road plant
Manufacturing area expanded to 21,000 m².
Headquarters base
A 48,000 m² headquarters base was established.
Capital market
Listed on the NEEQ and launched the Beijing Stock Exchange IPO process.
Engineering
and manufacturing
Product definition begins with operating conditions and continues through simulation, sample validation and stable volume production.
ROMAX-Assisted Engineering
From dimensions to load and stress analysis.
ROMAX simulation supports dimension definition, load modelling, modified-life calculation and subsurface raceway-stress analysis, helping shorten development cycles and improve first-pass engineering quality.
- 01Define installation envelope, speed, load, temperature and lubrication.
- 02Evaluate bearing parameters and stress through simulation.
- 03Coordinate samples, testing and technical feedback.
- 04Align product, manufacturing and delivery for volume introduction.
