Factors Affecting the Rotational Resistance of Idlers

  The rotational resistance of the idler rollers is influenced by various factors, and the following are the main ones:

  Bearing type: Bearings are an important factor that affects the rotational resistance of the idler rollers. Different types of bearing steel, such as long solid hardened bearing steel, induction hardened bearing steel, surface hardened bearing steel, stainless bearing steel, and high-temperature bearing steel, have different performance characteristics and have a direct impact on rotational resistance.

  Sealing structure: The sealing structure of the idler rollers is divided into contact sealing and non-contact sealing (labyrinth sealing). Contact seals, although effective in sealing, have a higher rotational resistance; non-contact seals theoretically have no frictional resistance and lower rotational resistance, but are not suitable for special environments, such as prolonged immersion in water.

  Processing and Assembly Quality: The quality of processing directly affects rotational resistance, including processes such as pipe cutting, drilling, chamfering, as well as the precision of bearing housings and shafts. Deviations in concentricity and straightness during the assembly process, as well as shaft deflection, can increase rotational resistance and even prevent the idler rollers from rotating.

  Adjusting the idler support: Adjusting the idler support is crucial for preventing conveyor belt misalignment, reducing material spillage, and minimizing equipment wear. Improper adjustment of the support structure can lead to a decrease in production capacity and efficiency.
