Hydraulic Seals have different sizes as per International standard. These sizes are determined by Piston Rod diameter, bore size of a hydraulic barrel and working pressure of the hydraulic system etc. PU Seal Size Chart is mentioned below…
How to determine the size of a PU Hydraulic Seal ?
In the above photo, few types of hydraulic seals are shown. It is seen that Wiper Seal, Rod Seal and Buffer Seal are directly connected with the piston rod. So, piston rod diameter size will be the inside diameter(ID) size of the Wiper Seal, Rod Seal and Buffer Seal.
Similarly, Piston Seal and Wear Ring are directly connected with the Cylinder. So, cylinder bore size will be the outside diameter(OD) size of the Piston Seal and Wear Ring.
Seal Mark on a Seal :
ID, OD and Thickness of any Hydraulic Seal are kept mentioned on the seal. So, you can identify the seal size by this. These sizes can also be found in the pu seal size chart.
