FR200 is a single acting rod seal, which is designed to ensure low friction force, reliable backpumping ability and superior sealing.
PRODUCT ADVANTAGES
• Superior static and dynamic sealing
• Low friction capability
• Increased extrusion resistance
• Reliable backpumping ability
• Operates well with a double wiper without a problem
APPLICATION
Construction machinery , fork-lift trucks , injection moulding machines , all hydraulic applications that need low friction force, metal working machines

| SURFACE ROUGHNESS | Ra | Rmax |
| Sliding Surface ?d | 0.05<=..<=0.4 ?m | <=3.2 ?m |
| Groove Base ?D | 0.20<=..<=1.6 ?m | <=10 ?m |
| Groove Flanks B | 0.20<=..<=3.2 ?m | <=16 ?m |
Note: It is recommended to have 50% to 90% of the working surface material contact area value.
INSTALLATION
Existing table values of K22 rod sealing element should be used to decide closed groove dimensions. Open grooves or special assembly tools should be used for the values that are outside this table. It is very important that the assembly tools must be of soft material and have no sharp edges. Before installation the rod seal must be oiled with system oil.
| PERMISSIBLE SEALING GAP |
| Smax (mm) |
| t=(D-d)/2(mm) | 150 Bar | 250 Bar | 400 Bar |
| t<=5 | 0.50 | 0.45 | 0.25 |
| t>5 | 0.60 | 0.45 | 0.35 |
Note: The largest sealing gap value occurring on the non-pressurized side of the seal does have a vital importance for the function of the seal and in this respect it is quite important to use the S value lower than the above indicated numbers.
