For a BU rod-seal inquiry, identifying the existing part is the first step. A readable marking, a cross-section drawing or an intact sample helps distinguish the sealing profile from other parts in the rod assembly. Rod diameter and groove dimensions are reviewed together with pressure and fluid before a replacement is proposed.
Typical applications
- Hydraulic cylinder rod-seal replacement
- Maintenance inquiries with an unidentified or worn original seal
What to include in an inquiry
- Send photographs of the BU marking and seal cross-section, or an intact sample
- Provide rod diameter, groove diameter and groove width
- Identify fluid, normal pressure and pressure peaks
- State stroke speed, temperature and leakage symptoms
- Include extrusion clearance and the condition of adjacent buffer and wiper seals
