13306941 Left rubber sleeve Sany SY1350C1C3KH Tracked hydraulic excavator spare parts

The 13306941 left rubber sleeve is a core protective component for construction machinery. It precisely adapts to the protection scenarios of critical components such as wiring, connectors, and shafts on the left side of equipment like Sany excavators and loaders. It is compatible with the protection needs of left-side components of similar specifications and is a dedicated protective sleeve for construction machinery. As a “protective barrier” for left-side components, its protective performance directly affects the service life and operational safety of critical equipment components. With its precision molding process, excellent flexibility, and stringent quality control, it has become the preferred choice for maintenance. It effectively solves the pain points of traditional rubber sleeves, such as easy cracking, aging, insufficient protection, and poor compatibility, reducing the risk of component wear, water ingress, and dust ingress, reducing maintenance costs, and ensuring the safe and stable operation of left-side components.
This product features a precise contour design with dimensional errors controlled within ±0.3mm. It accurately fits the shape of the left-side components of the equipment, offering strong adaptability and convenient installation. No special tools are required, and it can be quickly put on and taken off, tightly wrapping the protected area without loosening or falling off. It has excellent tensile and tear resistance, can adapt to vibration and deformation during equipment operation, is not easily damaged, and can effectively prevent the intrusion of dust, moisture, oil and other impurities, protecting critical components such as circuits, connectors, and shafts from damage and reducing the occurrence of downtime failures.
