Product Q&A

Q:What is a bogie spring used for?

Bogie spring is the core elastic component of bogie suspension systems for rail vehicles and heavy transport equipment. It bears vehicle body loads, absorbs shocks and vibrations from tracks, provides stable preload and evenly distributes dynamic loads. It stabilizes vehicle operation and protects bogie assemblies from excessive impact stress.

Q:What material are your bogie springs made of?

LUTONG bogie springs are produced from high-quality alloy spring steel. With professional heat treatment and coiling technology, the spring has high tensile strength, good toughness and superior fatigue resistance for heavy-load railway operating conditions.

Q:Can you offer OEM customization service?

Yes, OEM service is available. We can produce bogie springs according to your drawings, samples or technical specifications. The standard wire diameter is 24mm, and we can customize products for front or rear bogie installation.

Q:What certifications do your bogie springs have?

Our bogie springs are certified with ISO9001, ISO14001 and AAR standards. All finished products will pass strict quality inspection before delivery.

Q:What is your warranty period?

We provide a 1-year warranty for qualified bogie springs. Professional after-sales support will be offered if any quality problem occurs within the warranty period.
