Identification and purpose
Bushings DIN 1494 for high temperatures after heat treatment- steel bushing according to the drawing. Supporting, guiding or hinge unit of equipment. 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:are specified by a drawing of a specific position
- Material:not indicated in the individual name
- Hardness:exact value not specified
- Standard:DIN 1494
Values missing from an individual name are not replaced by general numbers for the product group.
Design and working unit
Bushings DIN 1494 for high temperatures after heat treatment 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.
- The name indicates heat treatment; the specific mode and controlled properties are specified by specification.
- The position is designated for high temperature conditions, but the temperature limit is not specified in the individual title.
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 with tolerances, material, required processing, quantity and control program.
