150101040039A002 Spring Sany SY1350C1C3KH Tracked hydraulic excavator spare parts

As a standard original part of SANY, this product precisely meets the needs of B-end procurement and technology selection, solves the core pain point of equipment elastic transmission, and has become the preferred choice for SANY equipment maintenance and assembly with its strict production standards and exquisite craftsmanship. It is compatible with major models such as excavators and mining wide-body trucks, covering multiple operating scenarios such as mining and construction, and is a key elastic component for stable equipment operation.
This product follows SANY’s original technical specifications and uses high-quality chromium alloy spring steel. It undergoes advanced processes such as three-stage high-pressure treatment and surface shot peening to significantly improve elasticity, toughness, fatigue resistance, and corrosion resistance. It resists high-frequency expansion and contraction losses, reduces failure rate and maintenance costs, and can stably perform buffering and reset functions for a long time under complex working conditions.

Core technical parameters:

– Product Model: 150101040039A002
-Product Name: Spring
– Compatible models: SANY excavators, mining wide-body trucks, and other original equipment manufacturer (OEM) designated models.
– Material specifications: High-quality chromium alloy spring steel (compliant with SANY original factory standards)
– Processing technology: precision rolling, three-stage high-pressure treatment, surface shot peening, and colored electrophoretic paint treatment.
– Wire diameter specification: 2.5mm (tolerance ±0.02mm)
– Free height: 38mm (adapts to equipment installation space)
– Maximum working load: 180N (meets equipment buffering requirements)
– Elastic modulus: 8.5 N/mm (elastic stability with no attenuation)
– Service life: ≥10,000 cycles of extension and retraction under normal working conditions (exceeding the industry average).

Compared to ordinary springs, this product has three major advantages: First, it is factory compatible, requiring no modification for direct installation, reducing compatibility risks and costs; second, it is highly durable, with high-quality materials and advanced technology, reducing replacement frequency and maintenance costs; and third, it has stable elasticity, with smooth extension and retraction without jamming, avoiding equipment failure caused by elasticity failure, meeting the needs of “cost reduction and efficiency improvement”.
As an original SANY component, it can directly replace old springs and is widely used in various engineering scenarios, compatible with all SANY models. Relying on the original manufacturer’s supply chain, it ensures a stable supply of genuine products and provides comprehensive after-sales technical support, helping users operate their equipment efficiently and reduce operating costs.
