STOBER Continues to Invest in the World’s Toughest Gearbox


Harsh environments easily cause premature failure for gearboxes. From caustic chemicals to water ingress to washing pressure, gearboxes face numerous challenges that can lead to early problems. One of the main issues is seal degradation.

Seals have the potential to be a weak point for gearboxes. Chemicals can eat away at the seal’s coating, allowing contaminants to enter a unit. Motor inputs can have water ingress, causing the input to leak. STOBER wanted to prevent premature failures in its products by installing long life seals in its input.

STOBER gearboxes feature a Freudenberg MSS1 seal, which has a long service life. This seal has high resistance to soiling and metal abrasion in the oil chamber. By using only the best components and focusing on longevity, STOBER is “The World’s Toughest Gearbox.”
