805400009 XCMG GR2605 motor grader retaining ring

805400009 XCMG GR2605 motor grader retaining ring

The 805400009 retaining ring is a core limiting and protective component in the hydraulic system, transmission mechanism, and connecting parts of construction machinery. It is used for shaft hole positioning, preventing component movement and detachment, ensuring the stability of the assembly structure and operational safety, and is suitable for heavy-duty, high-frequency operation conditions of construction machinery equipment.

Core Technical Parameters

Model: 805400009
Suitable Equipment: Hydraulic pipelines, transmission mechanisms, and shaft hole connecting parts of construction machinery (excavators, loaders, bulldozers, etc.)
Material: High-quality spring steel / carbon structural steel (high strength, high elasticity)
Surface Treatment: Blackening treatment / Zinc plating passivation (rust prevention, corrosion resistance, suitable for harsh outdoor environments)
Operating Temperature: -40℃ ~ +120℃
Installation Type: Shaft retaining ring / Hole retaining ring (suitable for shaft hole positioning and installation requirements)
Match Accuracy: High-precision machining, fits perfectly with shaft/ Hole clearance matching ensures a secure and stable installation.

Load characteristics: Withstands axial limiting loads, preventing component movement and detachment; excellent impact and fatigue resistance.

Core functions and roles

Axial limiting: Precisely limits the axial movement of shafts and parts, preventing components from detaching or shifting during equipment operation, ensuring structural integrity.

Positioning and fixing: Provides precise positioning for shaft-hole connections, ensuring the coaxiality and installation accuracy of assembled components, and improving overall structural stability.

Protective buffering: Absorbs axial impacts and vibrations during operation, reducing hard contact and wear between components, and extending the service life of core components.

Sealing and protection assistance: Used in conjunction with pipelines and bushings to prevent seals and connectors from failing due to movement, improving system sealing and operational reliability.

Suitable scenarios

Mainly used in hydraulic pipeline connections, transmission shafts, shaft-hole assembly, and bearing positioning in construction machinery. Widely compatible with the transmission and hydraulic systems of excavators, loaders, bulldozers, mining machinery, etc., it is a key basic component in shaft-hole connections to prevent component detachment and ensure assembly accuracy.
