Product Detail

Product Description: Dust Ring 4043000055 for SDLG 956L Wheel Loader

The Dust Ring 4043000055 is a genuine SDLG sealing component, also referred to as a dustproof ring, engineered specifically for the pivot pin joints on the SDLG 956L wheel loader and its compatible model series, including the L956F, LG956L, and LG953. It plays a critical role as a dynamic sealing element on highly articulated pin connections — the primary point where dust, debris, and moisture could otherwise enter the pivot joint and accelerate component wear.

The 4043000055 Dust Ring conforms to the Chinese national standard LGB307-80. Within the SDLG parts classification system, this is the LGB307 series dust ring with a nominal inner diameter of 80mm. The LGB307 standard specifies dimensional and performance requirements for rubber dust seals used in construction machinery pivot joints. Components meeting this standard are validated for use under the specific articulation angles, load cycles, and environmental exposure typical of wheel loader working attachments.
