Drawing-based components
Cut and turned PTFE rings with annular, stepped or grooved profiles. Define radial fit, axial width and mating features for the installed assembly.
Procurement specification
These components are made to the required geometry. The drawing defines the finished dimensions and interfaces.
| Principal geometry | OD, ID and axial width |
|---|---|
| Cross-section | Rectangular, stepped or drawing-based |
| Features | Grooves, shoulders, holes or a defined split |
| Manufacturing route | Sheet cutting for flat rings; turning for profiled rings |
| Fit requirements | Housing and shaft interfaces at service conditions |
A ring drawing needs more than inner and outer diameters. The cross-section establishes whether the part is a flat annulus, a guide ring or a stepped component with locating shoulders.
Specify any split width and orientation where installation requires an open ring. An unspecified cut changes the component geometry and its assembled fit.
A guide ring carrying side load has a different duty from an insulating annulus. Identify the surfaces that carry force and whether relative movement occurs.
A PTFE ring is not automatically a sealing element. If the ring contains pressure, provide the sealing profile and gland arrangement so it is assessed as a seal.
Specific answers
Yes. Show the split geometry and installation clearance on the drawing.
No. A machined PTFE annulus has a specified section and stiffness. It does not provide the same elastic response as an elastomer O-ring.
