Distance ring for Palfinger PK38502D

The HBS1381 distance ring serves as a precision component within the Palfinger PK38502D crane assembly. Its primary function is to maintain the exact separation between mechanical parts, ensuring that components remain correctly positioned during operation. By establishing these specific tolerances, the ring prevents unwanted contact between moving parts, assists in uniform load distribution, and helps maintain the alignment of shafts or bearings within the crane structure.

This component is compatible with the Palfinger PK38502D truck-mounted articulated crane. In such systems, distance rings are typically utilized at key articulation points, within slewing systems, or near cylinder and boom supports. The precise thickness of this ring is critical for maintaining the mechanical integrity of the assembly, preventing friction, and ensuring that the crane mechanisms operate without misalignment or excessive play.

Distance rings are used throughout heavy machinery to manage tolerances between mating surfaces. By providing a fixed gap, they ensure that rotating or sliding components move freely without binding or causing premature wear on adjacent parts. Proper installation of these rings is necessary to keep the mechanical system within its design specifications and to prevent the development of excessive clearance that could lead to operational instability.
