Kobelco and Kemel

Headquartered in Tokyo, Japan, the company that would later become Kemel was founded in October, 1964. Kobelco Marine first started producing stern tube seals in 1966, and developed their expertise in this area over several decades. In parallel, Eagle Industry also produced and delivered stern tube seals to the marine industry as of 1968.

In 2004, the compatible marine businesses of Eagle and Kobelco integrated, forming Kobelco Eagle Marine, which changed its name to Kemel six years later. In 2012, the company was fully acquired by Eagle.

Kemel Kobelco Eagle Marine

Specialising in stern tube seal systems, the company continues to provide expert service, stern tube seals and other spare parts with a focus on environmentally friendly and sustainable solutions. Kemel prioritises high-quality design and manufacturing, not only for their customers, but also to minimise their impact on the environment.

This approach has won Kemel a loyal and growing customer base within the marine industry, as environmental goals become increasingly key for many of their customers and partners.
