Core Features
Axial positioning and locking: Embedded in an annular groove on the shaft, it provides rigid axial support, fixing the position of bearings, gears, and other parts, preventing axial movement and impact collisions.
Anti-loosening and anti-fall-off: The elastic structure generates preload force, adapting to the small tolerances of the groove, maintaining a locked state under heavy load and vibration conditions, preventing component loosening and subsequent failures.
Clearance compensation and absorption: Elastic deformation absorbs assembly gaps and operational impacts, reducing component vibration and noise, and minimizing wear on mating surfaces.
Assembly positioning datum: Provides a precise installation datum for bearings, seals, etc., ensuring component coaxiality and improving the operating accuracy of the transmission/hydraulic system.
Quick maintenance and disassembly: Can be easily installed and removed with dedicated snap ring pliers, facilitating component maintenance and replacement, and reducing downtime.
Product Superiority
Original Factory Precision Fit: Manufactured according to Komatsu original drawings, the inner diameter, thickness, and opening size perfectly match the shaft groove, with no fitting gaps. After assembly, it fits tightly against the shaft shoulder, with a positioning accuracy of ≤0.02mm, compatible with the tolerances of the entire D65/D85 series shaft system.
High Strength and Fatigue Resistance: Made of 65Mn spring steel, quenched and tempered, with a tensile strength ≥1000MPa, high elastic limit, and a fatigue life of over 10⁵ cycles under cyclic loads, suitable for heavy-duty vibration conditions in bulldozers.
Long-Lasting Elasticity and Anti-Loosening: The open elastic structure provides stable preload force, with elastic decay ≤5% within a temperature range of -40℃ to 120℃, maintaining a locked state for a long time without the risk of loosening.
Convenient and Efficient Installation: The standard opening design is compatible with universal snap ring pliers, requiring no special equipment for loading and unloading, increasing assembly efficiency by 50% and reducing maintenance costs.

Corrosion resistant and durable: The surface is galvanized and passivated, and can withstand salt spray for ≥48 hours. It is suitable for dusty and humid environments such as mines and infrastructure projects, and prevents rust and jamming.
Applicable Scene
Suitable for Komatsu D65/D85 bulldozers in heavy-duty continuous operation scenarios such as mining stripping, large-scale infrastructure, and land leveling. Especially suitable for key shaft systems such as gearboxes, final drives, and hydraulic cylinders. It is recommended to replace them at the same time as bearings and seals to improve the reliability of shaft system operation.
