Polyurethane Seals ODU type is a special piston seal suitable for the Chinese machinery and equipment market. The groove design can adopt the Chinese standard JB/ZQ4264.
Hydraulic Oil Seal ODU Applications:
Working pressure: ≤32MPa (PU)
Working temperature: -40℃~+80℃ (PU)
Working pressure: ≤32MPa (NBR)
Working temperature: -30℃~+100℃ (NBR)
Reciprocating speed: ≤0.5m/s
Media: mineral oil, air
Note: To prevent extrusion, it is recommended to install a retaining ring on the heel of the seal when the pressure is above 140bar.
Install:
Seals such as Piston Seal PU should have an axial clearance (see columns h and H in the table). Integral pistons are available. To avoid damage to the sealing lip, precautions should be taken to avoid sharp edges during installation.
Material:
KVK polyurethane material with a hardness of 90 degrees. High-performance NBR with a hardness of 88 degrees.
