150101090029A031 Spherical Bushing Sany SY1350C1C3KH Tracked hydraulic excavator spare parts

The 150101090029A031 spherical bushing is an independently developed and adapted product by SANY, which meets the needs of engineering machinery for high load, multi-angle swing, and precision guidance. It solves the industry pain points of traditional spherical bushings, such as rapid spherical wear, jamming, poor lubrication, and insufficient compensation for deviation. As the spherical support hub of the core component of the equipment, it directly affects the swing flexibility of the component 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: 150101090029A031 Spherical Bushing
– Material: Tin bronze alloy (ZCuSn10Pb10), aged and spherically polished, with a hardness of HB190-230. It has self-lubricating properties, is wear-resistant, anti-galling, and corrosion-resistant. It can withstand spherical oscillation loads and friction for a long time and is not easy to wear, deform, or jam.
– Spherical parameters: Spherical radius tolerance ≤ ±0.005mm, swing angle ±5°, suitable for spherical connection parts such as SANY plunger pumps and swashplate assemblies, smooth swing at multiple angles without jamming, can effectively compensate for installation deviations, and is suitable for complex construction scenarios such as mines and buildings.
– Accuracy grade: Dimensional tolerance ≤ ±0.004mm, spherical roundness ≤ 0.003mm, surface roughness Ra ≤ 0.03μm. Precision machining ensures tight fit of the spherical surface, flexible swing, reduces friction loss, and improves guiding accuracy.
– Structural design: The one-piece spherical surface is precision machined and formed. The inner wall has an annular lubrication groove to store grease and enhance the self-lubricating effect. The inner and outer spherical surfaces fit tightly and are installed with an interference fit, which is firm and free of looseness. The edges are chamfered for easy assembly and the service life is more than 3100 hours.
– Compatible Models: Designed specifically for Sany series, compatible with Sany 190 piston pump, swashplate assembly, drive shaft, various excavators and other construction machinery. It can directly replace the original spherical bushing without additional adjustment, with 100% compatibility.
– Operating temperature: -20℃~120℃, adaptable to extreme working conditions of high temperature, low temperature and high dust, it still maintains flexible spherical swing under various complex scenarios, with stable self-lubricating performance and is not prone to seizing or jamming.

Product advantages:

1. Original factory compatibility: SANY original factory specification spherical bushings, precisely match the spherical connection size and swing requirements of equipment, are easy to install, and solve the problems of spherical deviation, jamming and insufficient compensation of non-original factory bushings. The quality is consistent with the original factory and helps to achieve efficient operation and maintenance.
2. Wear-resistant and self-lubricating: The tin bronze material has self-lubricating properties. Combined with the lubrication groove design, it reduces spherical friction wear, is wear-resistant and anti-seize, effectively protects related parts, extends service life, and reduces maintenance frequency and downtime losses.
3. Flexible swing: Precision spherical machining allows for adaptive swing angles, effectively compensating for installation deviations. Smooth, unhindered swing at multiple angles ensures flexible operation of equipment components and improves overall machine stability.
4. 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 and maintenance, and professional technical support to eliminate any worries.

The 150101090029A031 spherical bushing, with its precision-crafted spherical support core, is an original factory-fitted component that ensures the flexible operation of equipment parts. It is a high-quality accessory for SANY equipment to improve swing flexibility, reduce costs and increase efficiency, and help users carry out construction efficiently.
