With the power to support, we drive the future.

TBK supports society with three strengths to realize a safe and sustainable future.
The reliability of our products that support mobility. The innovation of technologies that drive change. Harmony with the environment to pass on to future generations.
We continue to meet every challenge with the power to support.

Protecting mobility with the technology to stop.

In the harsh environments faced by large trucks, buses, and construction machinery, what is essential is the ability to stop reliably. TBK has supported vehicle safety and reliability through its long-cultivated expertise in drum brakes and pumps.
From brake responsiveness and durability to cooling and lubrication performance, everything is dedicated to the safety and peace of mind of people and mobility.
Our range of products, supporting from the unseen ground up, protects the world’s mobility by ensuring the power to stop.

Instilling innovation into the technology that supports.

From material processing and assembly to inspection and design, TBK’s technology is supported by an integrated system that takes responsibility for every stage of production.
Without being complacent about our established quality and track record, we continue to take on new challenges such as electrification, weight reduction, and optimizing energy efficiency for the next generation.
By combining on-site expertise with innovative design concepts, we instill innovation into our reliable support.
Even now, TBK’s technology is continuously evolving on the frontlines, always looking toward the future.

From the ground up, gentle on the earth.

TBK’s manufacturing is committed to supporting society and the environment, aiming for technologies that look toward the next generation. We develop enclosed structures to suppress brake dust dispersion, work on reducing and standardizing parts to minimize waste, and focus on environmentally conscious practices even in less visible areas.
By considering the entire product lifecycle, we strive to reduce CO₂ emissions.
While maintaining our dedication to “supporting from the ground up,” we continue to contribute to the realization of an earth-friendly mobility society.
