(RF905)
Seals that seal rings made of S-FLON(PTFE) are combined with O-rings made of synthetic rubber. No stick slip even in low pressure and low speed due to small friction characteristics. As seal rings(resin) are hard and lacking in elasticity, sealing performance is inferior a little compared with U-packings. Be careful to handle seal rings as they are easy to be specially influenced by cracks, etc.
# Cylinders for general industrial machines
# ST-type : Abundant size series for general use # Cylinders for special use# STR-type : Use for rolling joints

# Cylinders for agriculture machines
PENTA-Seals[Exclusively for rods]
Packings exclusively for rods. Compatible with O-rings of JIS B 2401 P-line. Better sealing performance than O-rings. No distortion and no damage due to rolling.
# Small diameter cylinders(Operating valves, solenoid valves)
HSD-Packings[Exclusively for pistons]
RN906Packings of both sides pressure type. Available for thin type design for pistons. Compared with O-rings, stable sealing performance is conducted without distortion and damage caused by rolling.
RGU-Packings[Exclusively for pistons ]
RN923Special one ring shaped packing for both sides pressure with seal lip. Has the same sealing performance as U-packing. Possible to make a piston compact. PWL-Bearings for bearings combined with back-up rings are being prepared.
SKY-Packings[For pistons and rods]
Most popular packing for hydraulic cylinders. Available for use for both pistons and rods. Available for mounting this packing in a solid groove. Possible to reduce the number of part items and conduct compact design. Effective in reducing cost.
KY-Packings [For pistons and rods]
Various sizes. Used for the various fields due to large section design. Conduct stable performance.
# Cylinders in the specification of cold resistance
T-SNY-Packings[Exclusively for rods]
RN809
T-SGY-Packings[Exclusively for pistons]
RN812 Packings exclusively for pistons and rods compatible in grooves with SKY-Packings. Available for use at -40 to 100 degree C. Unnecessary to replace packings in the specifications of domestic and overseas cold districts. Compared with other U-packings, designed hard to cause stick slip. Laying stress on cold proof, rubber hardness is restrained. Be careful in use under the conditions of high pressure and high frequency.
GPY-Packings[Exclusively for pistons]
RN919Packings exclusively for pistons and rods, respectively, using wear proof material. Section sizes for diameter sizes are made larger than those of SKY-Packings. Durability has been improved. GPY-Packings for pistons are hard to cause damage brought about by back pressure, while GNY-Packings for rods have been improved in sealing performance for good elastic seal materials.

The length of the lead-in chamfer “C” is criticalto successfully installing the seal withoutdamaging it in the process. The value for “C”is given for each seal on the following pagesand it is a function of the profile of the seal(dimension “B”).
The maximum allowable clearance gap is afunction of the system pressure and the profile(dimension “B”) of the seal. It should bedetermined using the highest operatingpressure the system will see. The value fordiameter D1 can be determined as follows:
D1 = d + (Max. Allowable Clearance Gap)
Please use the chart below to determine themaximum allowable clearance gap. Thesevalues are based on using non-metallic guideelements.

Fitting into Housing
When fitting the OMEGAT OMS-S into its housing, the rubber energizer is installed first. The PTFEprofile ring is then carefully formed into a kidney-shape and then snapped into the groove. Carefulattention must be paid when installing the PTFE profile ring to prevent sharp kinks from beingformed and to assure that the sealing edge is correctly aligned to the direction of the pressure. Alledges must be chamfered and burr-free to prevent damage to the seal during installation.

Surface Finish Clearance Gap, Diameter D1
Profile bearing length ratio Mr > 50% up tomaximum 90% with cutting depth c = Rz/2 andreference line Cref = 0%
The maximum allowable clearance gap is afunction of the system pressure and the profile(dimension “B”) of the seal. It should bedetermined using the highest operatingpressure the system will see. The value fordiameter D1 can be determined as follows:
D1 = d + (Max. Allowable Clearance Gap)
Please use the chart below to determine themaximum allowable clearance gap. Thesevalues are based on using non-metallic guideelements.
The length of the lead-in chamfer “C” is criticalto successfully installing the seal withoutdamaging it in the process. The value for “C”is given for each seal on the following pagesand it is a function of the profile of the seal(dimension “B”).

Features & Benefits
MERKEL T22 RodSealFeatures & Benefits
¨ The T22 Rod Seal provides superior sealing performance as a primary sealing element.
¨ Pocket formed between primary and secondary sealing edges provides a reservoir for lubrication,thereby reducing friction.
¨ Superior abrasion and wear resistance of our NOVATHAN ensures longer operating life thanother urethanes.
¨ Extrusion resistant material and design are engineered to withstand high pressures, up to 6,000psi (40 MPa).
¨ Dynamic sealing lips are knife-cut to exert maximum sealing force.
¨ Asymmetrical design positions seal securely in the housing to prevent twisting.
¨ Preload design seals effectively even with unpressurized system
¨ No adhesion effect on sliding surface, even after a long standstill.

Features & Benefits
DISOGRIN Symmetrical Rod SealFeatures & Benefits
♦ The Symmetrical U-cup provides excellent sealing performance and very long operating life inboth rod and piston applications.
♦ Knife-cut lips on both the dynamic and static sides assures maximum sealing force to preventleakage.
♦ The Symmetrical U-cup is made from DISOGRIN 9250, world renowned for its resistance to wearand tear and for its very low compression set. Its extrusion resistance is second to none. Theresult is superior sealing performance and longer operating life.
♦ The Symmetrical U-cup is resistant to pressure spikes and diesel effect. Capable of withstandingpressures up to 4,000 psi and 300°F (intermittent), the Symmetrical U-cup is a great for thosetough applications with high pressures or temperatures where other seals fail.
♦ No adhesion effect on sliding surface, even after a long standstill.
♦ Superior performance over a wide range of temperatures and hydraulic fluids.
