Stepped Shaft Main Shaft 45# Steel Solid End Face

Stepped Shaft Main Shaft 45# Steel Solid End Face

Product Description

This lifting main shaft is precisely turned from 45# steel with excellent comprehensive mechanical properties after quenching and tempering heat treatment. The integrated multi-step shaft body features high dimensional accuracy  and qualified coaxiality for stable transmission without shacking. Finely ground anti-rust surface fits assembly of drums, pulleys and other lifting parts, with strong bearing capacity and outstanding durability.

Technical Parameter

Matters Need to Attention

• Clean the fitting surface of the shaft before installation to avoid scratches and guarantee coaxiality.
• Do not strike the shaft violently to prevent bending and deformation of step sections.
• Apply even force during fitting bearings and drums to avoid shaft eccentricity from unilateral extrusion.
• Fill lubricating grease regularly to reduce wear; keep anti-rust treatment during storage.
• Stop operation for maintenance once shaft surface scratches or bending deformation occur.

Application

• Serve as the core transmission main shaft for crane and winch drums, bearing all working loads of drums and steel ropes, and transmitting torque for hoisting and luffing movements.
• Match fixed and movable pulley assemblies, support pulley rotation and guide smooth winding of steel wires.
• Connect the output end of winch reducer and driving parts to deliver power for lifting and traction of heavy loads.
• Widely applied in engineering cranes, port winches, mine hoists and other equipment as key load-bearing transmission parts of lifting mechanisms.
