Identification and purpose
Lightweight bushings Ø45–300 mm for large excavators, corrosion resistant- steel bushing according to the drawing. Excavator hinge or support unit. The exact installation location is confirmed by the assembly drawing.
The card refers to one independent item: its name and images are considered together, without adding photos or parameters of adjacent products.
Confirmed position characteristics
- Product type:Steel bushing according to drawing
- Model/Series:not indicated in the individual name
- Dimensions:45–300 mm
- Material:not indicated in the individual name
- Hardness:exact value not specified
- Standard:a separate standard is not indicated in the name
Values missing from an individual name are not replaced by general numbers for the product group.
Design and working unit
Lightweight bushings Ø45–300 mm for large excavators, resistant to corrosion, are considered as an independent part. The landing dimensions, working surface and interface are determined by its own drawing; visual similarity to another bushing does not indicate identical material, processing or interchangeability.
- Corrosion protection is claimed, but the type of coating and its control requirements must be specified when ordering.
Data for technical approval
Before calculating and starting production for this position, it is necessary to fix:
- outer and inner diameters, length and fit tolerances
- mating part, working gap and installation method
- material, heat treatment, roughness and coating
- load, movement, contamination and maintenance regime
Control and acceptance of the batch
Acceptance criteria are determined by the drawing and order. For this item, the control chart should separate the confirmed requirements from the preliminary ones:
- critical dimensions and tolerances with reference to position drawing
- identification of material according to the agreed document
- condition of the working surface, edges and installation areas
- marking, quantity and surface protection during packaging
Compatibility and Request Kit
Interchangeability is confirmed not by a photograph, but by the coincidence of the drawing, fits, associated parts and working conditions. To request, please attach a drawing or measured sample, specify the equipment designation, dimensions 45–300 mm, material, required processing, quantity and control program.
