Rail Transit Industry

Widely used in high-speed rail, subway, urban rail transit and railway vehicle supporting equipment, including rail vehicle transmission systems, bogie components, door system structures, control electrical components and track auxiliary equipment. The products undertake precision positioning, anti-loosening safety fixation, vibration buffering and stable torque transmission, ensuring long-term safe operation of rail transit equipment.

Rail transit equipment operates in long-cycle, high-frequency and strong vibration environments, requiring extremely high safety and fatigue resistance. Traditional fasteners are prone to loose failure after long-term vibration, causing potential safety hazards; ordinary elastic parts have poor fatigue resistance and are easy to age and fail; unstable raw material strength cannot meet the long-life and high-safety operating standards of rail transit equipment.

High-strength heat-treated strip steel and heavy-duty DIN fasteners provide super fatigue resistance and vibration resistance, adapting to long-term strong vibration operation of rail transit equipment; high-load flat keys and elastic washers maintain stable structural pre-tightening force, avoiding part loosening and failure; integrated high-standard matching solutions meet rail transit safety certification requirements. Our products eliminate equipment potential safety hazards, extend component service life, and guarantee the safe and stable operation of rail transit equipment.

Supporting rail transit supporting equipment manufacturers. 60Si2MN heat-treated strip steel elastic fasteners and DIN1481 heavy-duty flat keys are applied to rail vehicle bogie and transmission components, achieving long-term anti-loosening and zero-failure operation under strong vibration conditions.

Q1: Can your products adapt to long-term strong vibration rail transit working conditions?
A1: Yes. Our rail transit-grade products are made of high-strength spring steel such as 60Si2MN and SK85, with professional heat treatment strengthening process. They have excellent fatigue resistance and structural stability, fully adapting to long-term strong vibration and complex weather working conditions of rail transit equipment.

Q2: Do your products meet rail transit industry safety standards?
A2: All products comply with DIN industrial safety standards, with stable strength and high safety factor, meeting the supporting and safety operation requirements of rail transit auxiliary equipment.

FAQ

What documents can you supply for bulk purchasing inspection?

Material certificate, dimension inspection report and surface treatment test sheet can be issued as buyer’s requirement.

How about production lead time for stocked items and customized non-standard goods respectively?

In-stock standard goods ship within 7 working days; customized non-standard products take 30–45 working days after deposit confirmation.

Is mixed loading of different kinds of fasteners allowed in one shipment to save customer’s logistics cost?

Multiple product categories and mixed sizes can be packed together in one container for large orders to reduce overall freight expense.

Can you make different surface treatments such as black oxide, phosphating and oil coating according to customer requirements?

Multiple surface options are available for all products; surface processing plan can be adjusted based on client’s actual working environment.
