Parker’s BD Profile with Back-up is a single-acting, non-symmetrical profile rod seal for hydraulics. The o-ring energizer functions as a spring to maintain sealing contact for improved cold temperature sealing, and under low pressure or vacuum applications. The knife trimmed, beveled lip does an excellent job wiping fluid film. Its rectangular shaped cross section ensures stability in the gland. A stabilizing lip is located below the primary sealing lip, just above the base of the seal, to provide enhanced sealing performance and ensure a tight, stable fit in the gland. The heel design incorporates a positively actuated back-up ring for anti-extrusion and extended high pressure sealing capability.
Available in Parker’s proprietary urethanes, the BD Profile provides
• Long life
• Extrusion resistance
• Low compression set
• Shock load resistance, and
• Excellent sealing performance at zero pressure
The BD Profile With Back-up is designed to be used as a stand alone rod seal or for use with the BR Profile rod buffer seal for more critical sealing applications.
Improved extrusion resistance: For enhanced extrusion protection, the BD Profile With Back-up is designed with a positively actuated back-up ring located in the heel.
