RB NOK Asymmetrical Profile Rod U-Cup with Double Lip RB asymmetrical C-cup is suited for heavy duty mobile and stationary service when rod leakage must be kept to a minimum. Double lip design reduces fluid from passing outside the cylinder and stops contamination from entering the front sealing lip.

HBTS Profile NOK O-Ring Energized Low Friction PTFE Rod Seal This is used to absorb the impact and fluctuating pressure at high load, to isolate high temperature fluid, and to improve the durability of the packing. It has small friction resistance and is suitable for high speed, short stroke operation. A slit on the tapered surface can leak back pressure.

Technical Data

Pressure (Typ.)5100 PSI / 35 MPa

Linear Velocity 4.5 ft/s / 1.5 m/s

Temperature (NBR for low temp.)-55C/100C to -67F/212F

Temperature (FKM) -20C/160C to -4F/320F

This has the same function as HBY. It has small friction resistance that is suitable for high speed, extremely short stroke operations. A slit on the tapered surface (non-sliding surface) allows pressure to leak back. It is used in combination with rod packings to absorb the impact and fluctuating pressures at high load, to isolate high temperature fluids, and to improve the durability of the packing.

A626 uses general petroleum hydraulic fluid oil, water-glycol type hydraulic fluid oil, and oil-water emulsion type hydraulic fluid oil.

F201 uses general petroleum hydraulic fluid oil, and phosphate ester type hydraulic fluid oil.

HBY Profile NOK Buffer Seal with Anti-Extrusion Rings U-Cup with asymmetric profile of the sealing lips, and chamfered sealing edges with pressure - relieving capabilities to prevent inner pressure entrapment when employed in tandem sealing system. This rod seal is designed to absorb impact pressures and pressure fluctuations under high-load conditons, thus increasing the life of the tandem seal.

Technical Data

Pressure 8000 PSI / 55 MPa

Linear Velocity 1.5 ft/s / 0.5 m/s

Temperature -54C/149C to -65F/300F

This is used in combination with rod packing to absorb the impact and fluctuating pressures at high load, to isolate high temperature fluids, and to improve the durability of the packing. It has a special shaped slit at the sliding lip that can leak back pressure, and eliminates the pressure between the rod packing and the buffer ring. Used with general petroleum hydraulic fluid oil.

no adhesion effect on sliding surface relieves any pressure build-up which may occur superior abrasion and wear resistance
