BD rod-seal matching requires a section drawing of the groove and the seal rather than the profile code alone. The available groove space and clearances determine whether a proposed replacement fits. Fluid compatibility and the pressure cycle then guide the material review.
Typical applications
- Hydraulic rod sealing with a confirmed BD profile
- Replacement selection from groove and seal drawings
What to include in an inquiry
- Provide a section drawing showing rod diameter, groove diameter and width
- Include the original BD seal dimensions and marking
- State fluid and operating temperature range
- Describe normal pressure, pressure peaks and duty cycle
- Identify extrusion clearance, rod wear and installation access
