In the realm of port and terminal cranes, the use of dry sliding bearings has become increasingly prevalent due to their reliability, durability, and maintenance-free operation. Among these bearings, PAP10 and PAP20 are two commonly specified types that offer exceptional performance in demanding environments.

The slide paths, which are essential components of these bearings, play a crucial role in ensuring smooth and efficient operation. To further enhance the performance of these slide paths, PAS strips are often utilized as a material choice. PAS strips are specifically designed for high-load applications, such as port and terminal cranes, and are known for their excellent wear resistance and low friction properties.

The use of PAS strips in the bushings of PAP10 and PAP20 bearings helps to significantly reduce friction and wear, thereby extending the lifespan of the bearings and reducing the need for maintenance. This, in turn, leads to lower operational costs and improved productivity for port and terminal crane operators.

In addition to their performance benefits, PAS strips also offer excellent corrosion resistance, making them suitable for use in harsh marine environments. This ensures that the bearings can continue to operate reliably even in the most challenging conditions.

Overall, the combination of PAP10 and PAP20 bearings with PAS strips material in port and terminal crane bushes represents a significant advancement in terms of performance, durability, and maintenance-free operation. This technology is poised to become a standard choice for crane operators looking to improve their efficiency and profitability.

If these material sections are used to create slide paths, they have the following main functions:

 

• Absorbing and transferring forces acting vertically to the running surface
• Fixing moving components to each other
• Ensuring guidance accuracy for axial movements over the entire service life

Strusture

 
1. PTFE/Fibre mixture thickness 0.01~0.03mm. It is the contact surface for the rotating shaft. Minute partides of the PTFE layer and the sintered bronze material combine to create a solid lubricant film, which coats the shaft.
 
2. Sintered bronze powder thickness 0.20*0.35mm,A special composition of powdered copper is thermally fused to the steel backing. This contact layer acts as an anchor for the PTFE layer and conducts the thermal build up away from the bearing surfaces.

3. Low-carbon steel backing. Setting the foundation of the bushings, the steel back provides exceptional stability, load carrying and heat dissipation characteristics.
