Identification and purpose
High precision thin steel washers 40×80×3mm for sealing- round steel adjusting washer. Adjusting the gap or thickness of the package in a mechanical assembly. 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:Round steel shim
- Model/Series:not indicated in the individual name
- Dimensions:40×80×3 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
The adjusting washer sets the thickness of the package or the axial clearance in the assembly. For this position, the diameter and thickness cannot be transferred from the adjacent washer: the outer and inner diameters, flatness and condition of the edge are checked according to its drawing.
- The individual name does not indicate additional coatings or processing modes; they are specified by drawing.
Data for technical approval
Before calculating and starting production for this position, it is necessary to fix:
- outer and inner diameters, thickness and tolerance
- flatness, parallelism and edge quality
- material, hardness and surface condition
- single washer or assorted thickness pack
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
- thickness, flatness, parallelism and burr-free
- 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, indicate the designation of the equipment, dimensions 40x80x3 mm, material, required processing, quantity and control program.
