Frequently asked questions — Cast Iron Wheels

• How do I choose between a cast iron wheel for belt or chain transmission?

  The choice depends on the type of power transmission installed. For precision roller chain drives, the wheel design must meet the requirements of ISO 606. If the installation uses V-belts, the selection is based on compliance with the industrial standards ISO 4183 or DIN 2211, which define the appropriate groove profiles for pulleys.
• Which technical criteria guarantee the longevity of a FAIR Transmission cast iron wheel within a kinematic chain?

  The longevity of the mechanical assembly relies on strict compatibility between the wheel and adjacent transmission components, such as torque limiters, bushings or fixing systems. Precise alignment is essential. Technical selection must also include a rigorous analysis of the working environment, including rotational speed and transmitted forces, to ensure optimal operation of the components.
• Why comply with ISO 4183 or DIN 2211 when selecting a cast iron wheel for belts?

  These industrial standards are decisive in ensuring the efficiency of the transmission system. They enable the appropriate groove profiles to be defined for cast iron pulleys. Strict compliance with these standards guarantees compatibility with the V-belts used and ensures mechanical integrity during the operation of the power transmission.
• Should I opt for a cast iron wheel or another mechanical transmission component?

  Cast iron wheels are essential elements intended for transmission systems incorporating chains, belts or couplings. Your choice must meet the precise technical specifications of your installation, particularly the permissible load, the required diameter and the profile of the teeth or groove. Analysis of the kinematic constraints of your application will determine whether the cast iron wheel is the appropriate component compared with the other solutions in the Mechanical Transmission range.
