150101040039A029 Coupling sleeve Sany SY1350C1C3KH Tracked hydraulic excavator spare parts

The 150101040039A029 coupling sleeve is a dedicated transmission connection component for SANY engineering equipment. Adhering to original equipment manufacturer (OEM) specifications, it is precision-machined from high-quality alloy steel, balancing connection strength and buffering performance. It is precisely matched to SANY excavators, hydraulic pumps, motors, and other main machine models, used for shaft connection between the equipment’s motor, gearbox, and working mechanism. It transmits power, buffers vibration, compensates for shaft installation deviations, and avoids transmission noise, component wear, and other faults. Suitable for mining, construction, and other scenarios, it is the preferred OEM part for B2B procurement and equipment maintenance.
This product addresses the pain points of ordinary coupling sleeves, such as loose connections, insufficient buffering, and easy wear. Rigorous manufacturing processes ensure that the structural strength and transmission accuracy meet original equipment manufacturer (OEM) and national coupling standards. It can withstand high-speed equipment operation, vibration, impact, and harsh working conditions, reducing replacement and maintenance costs and meeting the needs of “cost reduction and efficiency improvement, and stable transmission”.
This product is made of high-quality alloy steel and undergoes precision turning, surface hardening, keyway precision machining, and dynamic balancing calibration to improve connection strength, wear resistance, and buffering effect. It can effectively compensate for minor axial and radial deviations and has a service life far exceeding that of ordinary couplings. It has a compact structure, is easy to disassemble and assemble, and can be directly adapted to Sany models without modification, reducing adaptation and installation costs.

Core technical parameters:

– Product Model: 150101040039A029
– Product Name: Coupling Sleeve (Sany Exclusive Original)
– Compatible models: SANY excavators, hydraulic pumps, motors, and other original manufacturer-specified models.
– Material specifications: High-quality alloy steel (original factory standard, heat treatment, hardness HB260-300)
– Machining process: Precision turning, surface hardening, keyway machining, dynamic balancing calibration, precision testing
– Inner diameter specification: 45mm (tolerance ±0.01mm, suitable for equipment shaft diameter)
– Outer diameter specification: 75mm (to fit the equipment installation space)
– Length specification: 55mm (balancing connection strength and ease of installation)
– Applicable speed: ≤2800r/min (meets the high-speed transmission requirements of equipment)
– Transmitted torque: ≥450 N·m (highly efficient and lossless power transmission)
– Service life: ≥12,000 hours under normal operating conditions (exceeding industry average)
– Quality Standards: ISO9001 certified, traceable to the original manufacturer, conforms to GB/T 5843 standard.

Compared to ordinary non-standard couplings, this product has three major advantages: First, it is a precise original factory fit, requiring no modification for direct installation. The keyway fits tightly with the shaft system, compensating for installation deviations and reducing costs. Second, it is reliable in quality, wear-resistant, deformation-resistant, and has good cushioning and shock absorption effects, reducing the frequency of replacement. Third, it is cost-effective, with a stable supply of genuine original factory products and excellent after-sales service, making it the preferred choice for shaft connections in Sany equipment.
This product can directly replace old coupling sleeves and is widely used in various engineering scenarios. Relying on the original manufacturer’s supply chain, it ensures a stable supply of genuine products and provides comprehensive after-sales service to help users reduce operation and maintenance costs and ensure efficient and stable power transmission to equipment.
