Choosing the right material for a cojinete de giro is crucial for its performance, longevidad, and overall cost-effectiveness. los “best” material depends heavily on the specific application, load requirements, environmental conditions, y presupuesto.
Slewing Bearing Materials
Races (Rings): Typically made from hardened steel.
Acero carbono (p.ej., 1045, 1050): Most common and economical choice for light to medium-duty applications.
Alloy Steel (p.ej., 4140, 4340, 50CrMo4, 42CrMo4): Offers higher strength, tenacidad, resistencia al desgaste, and hardenability. Used for medium to heavy-duty applications.
Acero inoxidable (p.ej., 304, 316, 440do): Used in corrosive environments or where hygiene is critical (procesamiento de alimentos, marine applications, Equipo medico). 440C is often used for races that require hardening.
Rolling Elements (Balls or Rollers): Usually made from high-carbon chromium bearing steel.
High-Carbon Chromium Bearing Steel (p.ej., 52100, 100Cr6): The industry standard for rolling elements due to its exceptional hardness, resistencia al desgaste, and ability to withstand high contact stresses.
Ceramic (p.ej., Silicon Nitride – Si3N4): Used in specialized applications where extremely high speeds, high temperatures, or non-magnetic properties are required.
Acero inoxidable (p.ej., 440do): Used in corrosive environments for rolling elements.
Cage/Separator: Keeps rolling elements separated and evenly spaced. Materials vary depending on the application.
Acero (p.ej., Low-Carbon Steel, Acero inoxidable): Common for general-purpose applications.
Brass/Bronze: Offers good wear resistance and damping properties.
Polyamide/Nylon (Plastic): Lightweight and quiet, suitable for lower-speed applications.
Factors to Consider When Choosing Materials
Load Requirements:
Static Load: The maximum load the bearing must withstand when stationary. Higher loads require stronger materials like alloy steels.
Dynamic Load: The load the bearing must withstand while rotating. This affects fatigue life, so materials with higher fatigue strength (p.ej., alloy steels, high-carbon chromium steel for rolling elements) are needed.
Impact Load: Sudden, high-energy loads. Require materials with high toughness and impact resistance (p.ej., certain alloy steels).
