Product Description

Product Overview

Our High-Strength Hammer Shaft Assembly is designed specifically for coal mine hammer crushers operating under heavy-duty conditions. It serves as the core rotating component that holds and drives the hammers, ensuring continuous and efficient crushing of coal and other minerals.

Specification

The shaft is manufactured from high-quality 42CrMo forged alloy steel, known for its excellent toughness, wear resistance, and fatigue strength. Each unit undergoes strict heat treatment (quenching and tempering) to achieve optimal mechanical properties and ensure reliable performance in high-impact mining environments.

Design Features

This assembly includes the main shaft, end disks, locking sleeves, hammer mounts, and fastening hardware, all precisely machined for superior balance and durability. The well-engineered design minimizes vibration, reduces mechanical stress, and extends the service life of the crusher.
