Lignite and coal mines, certain underground mines and some industrial plants require products specifically prepared for explosive environments.

At ULMA, we develop products whose components and manufacturing processes are specially designed to mitigate explosion and fire risks.
These products comply with the ATEX directive.

ULMA offers a wide range of rollers designed for standard operating conditions as well as for more demanding environments. All of them are manufactured using high-quality components and rigorous manufacturing processes, incorporating our own sealing systems that ensure effective sealing, optimal bearing protection, and reliable, long-lasting operation in any application.
