Mechanical Features

• Dynamic Load Rating : Indicates the bearing's ability to support variable loads during operation. A value of 925 kN denotes significant robustness, suitable for applications with high loads.
• Static Load Rating : Indicates the ability to support fixed loads. At 1330 kN, the bearing is designed to withstand significant static loads without deforming.
• Limiting Speed : The maximum speed at which the bearing can operate without compromising its life. The difference between the limiting speeds with grease and oil reflects the bearing's ability to handle different lubricants.

Mathematical Formulas and Parameters

• Bearing Life:
  • Bearing life can be calculated using the formula: L10=CrFr3×1000L_{10} = \frac{C_{r}}{F_{r}}^{3} \times 1000 $$L$$ 10 ​= F r ​C r ​​3 $$\times$$ $$1000$$ Where CrC_{r} $C$ r ​is FrF_{r} $F$ r ​is
• Working Speed:
  • The maximum operating speed depends on the type of lubricant used and the applied load. It is useful to consider: nmax=VlimitD×1000πn_{max} = \frac{V_{limit}}{D} \times \frac{1000}{\pi} $$n$$ ma x ​= D V l imi t ​​× π 1000 ​Where VlimitV_{limit} $V$ l imi t ​is DD $D$ is the bearing diameter.
