ATC-SM Material Composition

ATCORP, ATC-SM bearings are made via powder metallurgy, with solid lubricants like graphite uniformly embedded in a bronze, iron, nickel, or stainless-steel matrix. This differs from traditional oil-impregnated porous bronze, making ATC-SM more resilient and better suited for heavy-duty applications. ATC-SM is a single layer material suitable for both rotating and oscillating movement and are particularly effective under conditions of high load and moderate speed. They are commonly used in various applications, such as agricultural machinery, Hydro Turbines, Steel Plants, injection moulding machine, tire moulding machines, Special Purpose machines, Railways and many other applications.

Benefits of ATC-SM

  • Maintenance-free:ATC-SM bushes have a porous structure with integrated graphite, which acts as a solid lubricant. As the shaft rotates, the graphite releases a thin, dry lubricating film, eliminating the need for external lubrication.
  • Reduced friction:The constant presence of the graphite lubricant reduces the friction Coefficient, which decreases wear and tear on both the bush and the shaft.
  • Operates without grease or oil:This property makes ATC-SM ideal for applications where traditional lubrication is difficult, costly, or undesirable due to contamination risks, such as in food processing or textile manufacturing.
  • High load capacity:The metallic bronze matrix provides strong structural support, allowing the bushes to handle significant weight and stress, especially at low speeds.
  • High thermal conductivity:The bronze base is an excellent conductor of heat, which helps dissipate frictional heat and prevents overheating.
  • Excellent wear resistance:The combination of bronze and graphite provides a high level of durability, extending the equipment's service life even under demanding conditions.
