60221652 Locking sleeve Sany SY1350C1C3KH Tracked hydraulic excavator spare parts

The Sany 60221652 locking sleeve is a core keyless connection component in the transmission system of Sany construction machinery. It is specifically designed for the connection between the gearbox, drive axle, pulley, and shaft. Its core function is to generate radial tightening force through bolt locking, achieving a high-precision keyless connection between the shaft and the hub, transmitting torque, preventing component loosening and displacement, and undertaking the key roles of locking, connecting, and resisting torsional load. It is compatible with Sany and various mainstream construction machinery and is widely used in excavators, crawler cranes, loaders, and other models. It is suitable for harsh working conditions such as mining and infrastructure construction and is the preferred component for aftermarket maintenance, parts wholesale, and foreign trade export.
This locking sleeve relies on professional connecting component manufacturing technology and strict quality control. It is made of high-quality 40Cr alloy structural steel, which has high strength and excellent toughness. It is precision forged, CNC turned, tempered, surface hardened and rust-proofed. It has precise dimensions and no burrs, a surface hardness of HRC50-56, a tensile strength of ≥980MPa, and is wear-resistant and torsional resistant. It can achieve inner ring contraction and outer ring expansion through axial bolt tension, so that the mating surfaces fit tightly and transmit torque. It solves the pain points of locking sleeve loosening, wear, deformation and connection gap, etc., extends the overall service life of the transmission system and is suitable for long-term harsh working conditions.
