Hydraulic buffer seal, with slide ring and energizer

These hydraulic buffer seals consist of a PTFE slide ring and a nitrile rubber energizer that keeps the slide ring in its proper position against the rod seal side of the housing. This design ensures that the buffer seal is positioned to handle any pressure spikes that might occur in the hydraulic cylinder. On request, for the most demanding applications of large equipment, SKF can manufacture these with polyamide slide rings for additional extrusion and wear resistance.

• Provides protection for rod seals in applications where conventional buffers are not sufficient
• Provides improved gap extrusion resistance at abrupt pressure peaks
• Suitable for medium to heavy duty applications
• Accommodate pressures up to 400 bar (5 800 psi)
• Available in inch sizes
