Title
(EN) TEXTURED SEAL FOR REDUCED WEAR
(FR) GARNITURE MECANIQUE TEXTUREE PERMETTANT UNE REDUCTION DE L'USURE
Abstract
(EN)
A seal (10) has a contact surface (36) with textured features (41, 41', 41'', 41'''). The contact surface (36) seals properly and is resistant to wear. The contact surface (36) is able to perform in very severe environments, such as those found in earthmoving applications.
(FR)
La présente invention concerne un joint (10), une surface de contact texturée par endroits (41, 41', 41'', 41'''). La surface de contact (36) étanchéifie correctement et est résistante à l'usure. La surface de contact (36) est susceptible de s'adapter à des conditions très dures, telles que celles que l'on trouve dans des applications de terrassement.
