Calculate optimal nominal volume, operating pressure and N2 pre-charge using our certified sizing engine.
Open Volume Sizing Calculator →The SCHWERLL gas‑liquid piston‑type shock absorber is a high‑precision damping device. Compared with spring‑based dampers, it offers superior repeatability and smoother vibration suppression, and when installed in vehicle seats or speedboat seating, it can effectively enhance driver comfort.

Direct technical answers from Schwerll fluid power application engineers regarding Gas–liquid piston-type shock absorber.
SCHWERLL's gas-liquid piston-type shock absorbers are rated for continuous operation up to 207 MPa (30,000 psi) with a response time of less than 5 milliseconds. The piston design ensures minimal friction and leakage, making it suitable for extreme pressure spikes and high cycle frequencies.
Every Schwerll accumulator is designed, inspected, and validated against international safety and quality standards.
Complete Quality Management System certification across raw material testing, precision machining, honing, welding, and final FAT pressure testing.
ASME U-stamp and National Board (NB) registration available for high-pressure piston series (up to 30,000 PSI / 207 MPa) for North American & offshore deployment.
