150101090029A030 Spring Sany SY1350C1C3KH Tracked hydraulic excavator spare parts

150101090029A030 Spring Sany SY1350C1C3KH Tracked hydraulic excavator spare parts

The 150101090029A030 spring is an independently developed and adapted product of Sany, which meets the high load, high frequency extension and contraction, and impact resistance requirements of engineering machinery. It solves the industry pain points of traditional springs such as rapid elastic decay, easy breakage, deformation, and fatigue failure. As an elastic support and reset component of the core component of the equipment, it directly affects the sensitivity of the component’s movement and the stability of the whole machine operation. Its adaptability and durability are outstanding, which helps the equipment to operate and maintain efficiently.

Core technical parameters:

– Model: 150101090029A030 Spring
– Material: High-strength spring steel (60Si2Mn), quenched and tempered at medium temperature, with a hardness of HRC48-52. The surface is galvanized for corrosion protection. It has excellent elasticity, wear resistance, fatigue resistance, and corrosion resistance. It can withstand high-frequency expansion and contraction loads and impact loads for a long time and is not prone to elastic decay, breakage, or deformation.
– Elastic parameters: Rated load 120N, elastic modulus 206GPa, free length 58mm, compression 15mm. It is suitable for elastic reset parts such as Sany plunger pumps and check valves. It has precise elastic reset and good buffering and shock absorption effect, and is suitable for complex construction scenarios such as mines and buildings.
– Precision grade: Dimensional tolerance ≤ ±0.005mm, spring pitch tolerance ≤ ±0.1mm, surface roughness Ra≤0.05μm. Precision rolling ensures uniform elasticity, high reset accuracy, reduces component movement deviation, and improves equipment operation stability.
– Structural design: Precision rolled into one piece, with both ends ground flat for uniform stress distribution. It adopts a closed-loop structure, which has strong elastic recovery and excellent fatigue resistance. The surface has a uniform anti-corrosion coating, which is dustproof and corrosion-resistant, easy to assemble and maintain, and has a service life of more than 3,000 hours.
– Compatible Models: Designed specifically for Sany series, compatible with Sany 190 piston pump, check valve, swashplate assembly, various excavators and other construction machinery. It can directly replace the original spring without additional adjustment, with 100% compatibility.
– Operating temperature: -25℃~120℃, adaptable to extreme working conditions of high temperature, low temperature and high dust, and maintains stable elasticity in various complex scenarios, and is not prone to elasticity decay, aging or breakage.

Product advantages:

-Original factory compatibility: SANY original factory specification springs, precisely matching the elastic reset requirements of equipment. The size and elastic parameters fit perfectly, making installation convenient. It solves the problems of non-original springs having elastic deviation, easy breakage, and affecting the operation of components. The quality is consistent with the original factory, helping to achieve efficient operation and maintenance.
– Stable elasticity: High-strength spring steel with precision rolling process and professional heat treatment result in uniform elasticity, strong resilience, and excellent fatigue resistance. There is no significant elastic decay after long-term use, ensuring accurate component reset and shock absorption.
– Wear-resistant and corrosion-resistant: The surface is galvanized for corrosion protection, making it wear-resistant and corrosion-resistant. It can withstand the erosion of complex working conditions, reduce the risk of wear and breakage, extend service life, and reduce maintenance frequency and downtime losses.
-Excellent value for money: Original factory quality is guaranteed, affordable pricing, compatible with maintenance and repair, cost savings for both bulk and single purchases, easy assembly without additional debugging, and professional technical support to eliminate any worries.

The 150101090029A030 spring, with its elastic core crafted using precision engineering, is an original factory-fitted component that ensures accurate reset of equipment parts. It is a high-quality accessory for SANY equipment, enhancing its operational sensitivity, reducing costs, and increasing efficiency, thus helping users to carry out construction efficiently.
