Bronze Wear Parts for Mining Equipment

Bronze bearings and bushings guarantee performance in heavy-duty crushers and mining equipment

Heavy loads, strong vibrations, and constant dust exposure put a lot of stress on mining equipment. Bronze bushings and bearings made from tin or aluminum bronze can easily handle these conditions, as they have low friction, high strength, and self-lubricating properties. Their long life means that mining equipment doesn't need to be serviced as often, even in the most difficult working conditions.

• Heavy-duty crushing equipment
  In equipment such as cone crushers, bronze bushings are installed around the main shaft to handle strong radial loads and frequent impacts. Their high strength and resistance to deformation help the equipment maintain stable, continuous operation under demanding conditions.
• Hoisting and lifting systems
  In winches and mine hoists, bronze bearings are usually processed through laser cladding because this process strengthens the surface and improves lubrication, so the parts stay smooth in motion and resist wear even under heavy loads.

• Wear Resistance and Load Capacity
  Bronze alloys such as tin and aluminum bronze combine high hardness with excellent fatigue strength, making them suitable for heavy-impact mining conditions. Leaded bronze bushings, for example, perform well under high-speed and high-load operations thanks to their crack resistance. Since the bushings are formed in one solid piece without seams, it eliminates potential stress points, which helps prevent cracking and extends its service life.
• Self-Lubrication and Low Maintenance
  Some bronze bushings are embedded with solid lubricants like graphite, which create a smooth layer that reduces friction and limits the need for external oiling, especially useful for underground machinery where maintenance is difficult. When used with lubricating oil, the bronze surface helps maintain a steady oil film that prevents abrasive wear in dusty environments.
• Corrosion Resistance and Environmental Adaptability
  Bronze holds up much better than steel when exposed to moisture, mine water, or salt mist, which are common in underground environments. Thanks to its thermal stability, bronze maintains both its hardness and dimensional accuracy under high temperatures found in mining operations such as tunneling or drilling, preventing deformation or early fatigue.

• For heavy-duty or impact applications, aluminum bronze (ZCuAl10Fe3) wear parts are used because this material offers high strength and strong resistance to deformation. In environments with high humidity or chemical exposure, tin-phosphor bronze wear components provide better corrosion resistance. For precision transmission parts, laser-cladded bronze parts are ideal since it improves surface hardness and wear resistance.
• Bronze bushings can be customized to different machines, including options with flanges or lubrication grooves. In grinding mills, for example, the groove layout can be customized to improve oil distribution and improve overall lubrication performance.
• In mining equipment, bronze bushings can last two to three times longer than the standard ones, which means less downtime and fewer replacements.
• The self-lubricating properties lower oil consumption and reduces waste, preventing contamination in mining areas and supporting more sustainable operation practices.

In short, bronze bearings, bushings and other wear parts have become essential components in mining equipment, helping improve performance and reduce maintenance costs. As material technology continues to advance, their reliability makes them a solid choice for today’s and future smart mining operations.
