A151 hydraulic rod nutrings
A151 single acting rod seal has a shorter inner lip and is designed to be used in rod applications of medium duty hydraulic cylinders. It is produced in NBR Shore 90 and PU Shore 92 as a standard. It offers easy assembly into closed grooves, superior dynamic and staticsealing within the hydraulic system, economical sealing solution, and is available in a wide range of metric and imperial dimensions.
It is suitable for use in construction machinery, moving and loading platforms, forklifts, agricultural machinery, injection moulding machinery, as well as any other medium duty standard cylinders.
