Elastic star coupling with XL shaft hole enlargement

Structural features :

  • This part is similar to the basic XL model, but is suitable for installations with larger hole diameters.
  • The design is compact and lightweight, with low rotational inertia.
  • The shaft bushing is made of steel, making it particularly suitable for heavy-duty drive units such as air compressors, lifts, rolling mills and construction equipment.
  • The material of the elastic element is polyurethane. For high-load transmissions, a Shore A 98 (red) hardness element can be chosen.
  • The marking method is the same as for the basic XL model. An example of marking is “XL4D80L114YA38-42
