In heavy-duty, high-impact machinery like punch presses (stamping presses), bronze bushings (typically made of bronze or aluminum bronze) are more commonly used than steel bushings or rolling bearings. The key reasons include impact resistance, self-lubrication, wear resistance, and maintenance costs. Below is a detailed analysis:

Aluminum bronze sleeves (bushings) are highly durable and perform exceptionally well under harsh environmental conditions due to their unique alloy composition (typically Cu-Al with Fe, Ni, or Mn). They are chosen over standard brass or plain bronze bushings when extreme wear resistance, strength, and corrosion resistance are required.
