HBTU Rod Seal – Heavy-Duty Double-Acting Hydraulic Rod Seal with U-Cup and Multiple Backup Rings
Heavy-duty HBTU rod seal with U-cup geometry and multiple backup rings for extreme-pressure hydraulic cylinders. Anti-extrusion, low-friction, PU. –40°C~110°C, ≤50 MPa.
HBTU Rod Seal – A rugged heavy-duty hydraulic rod seal engineered for extreme-pressure and high-cycle double-acting cylinder applications. This U-cup rod seal features a multi-backup ring configuration that provides superior gap resistance under severe pressure spikes, shock loads, and side forces. The multi-lip sealing profile ensures reliable bidirectional sealing in both dynamic and static conditions, while the high-modulus polyurethane compound delivers outstanding abrasion resistance and thermal stability. The multiple-ring protection system prevents extrusion into radial clearances, maintaining seal integrity even under alternating pressure and side-load conditions. This heavy-duty sealing solution is ideal for mining equipment, construction machinery, off-highway vehicles, and heavy industrial hydraulics. Material: high-modulus polyurethane with robust backup rings. Temp: –40°C to +110°C. Pressure: up to 50 MPa. Speed: up to 2 m/s.
