LANDING GEAR ROLLER – KRONE

Guide roller for the support system – KRONE – Dimensions: Ø22 x 21 x 78 mm

The landing gear roller with the dimensions Ø22 x 21 x 78 mm is an essential mechanical component for the landing gear structure of Krone semi-trailers. This part ensures smooth movement during the lowering or raising of the support legs, a critical action in parking or coupling/uncoupling processes from the tractor unit.

Due to the precise geometric tolerances and the durable materials from which it is manufactured, the roller guarantees the stability of the entire support system, reducing friction and extending the service life of metal sub-assemblies even under intense daily operating conditions.

Main technical specifications:

Main advantages of the Krone Ø22x21x78 mm roller:

• Geometric precision: Perfect fit with factory parameters, eliminating unwanted mechanical play.

• Superior durability: Excellent resistance to static loads and high dynamic pressures.

• Structural protection: Prevents deformation and blocking of the internal elements of the landing gear.

• Reduced maintenance: The low coefficient of friction minimizes wear, even in harsh working environments.

• Operational efficiency: Facilitates fast and effortless handling of the lifting/lowering system.

Application areas and usage:

This component is widely used in the support systems of heavy commercial vehicles for guiding internal telescopic elements. Its presence prevents direct metal-on-metal contact, ensuring uniform, silent movement and protecting gear mechanisms against premature wear.

Target audience:

• Owners and managers of Krone semi-trailer fleets;

• Road transport and international logistics companies;

• Auto service workshops specializing in the maintenance of superstructures and running gear;

• Suppliers and distributors of spare parts for commercial vehicles;

• Professional drivers who perform basic maintenance on their own equipment.

Conclusion

The Krone Ø22x21x78 mm support roller is an indispensable component for the safety and efficiency of coupling and uncoupling operations. Choosing this part ensures perfect compatibility with the original system, increasing the reliability of the landing gear and reducing long-term maintenance costs for your semi-trailer.
