For hydraulic cylinder rods, the SKF RGRW series seal keeps pressurized fluid in and contaminants out, protecting internal components and supporting reliable operation. It is a lip seal suited to reciprocating motion in equipment such as presses, excavators, and lifting systems, where sealing integrity and low friction matter. MR supplies this line and can help you match the right variant to your application.
The RGRW code combines a base designation with numbers that point to a size in the family, for example RGRW108. Those digits often relate to rod and housing diameters, but each size has its own design. Use the manufacturer's size table or send the complete part number rather than assuming that close numbers mean interchangeable sizes.
Typical installations include hydraulic cylinders on earthmoving and road equipment, industrial presses, and automation systems. Metalworking, mining, construction, and agriculture are common sectors, since equipment there runs at high pressure and in demanding conditions. The RGRW series fits rod applications with reciprocating motion, where wear resistance and compatibility with standard mineral and hydraulic oils are required.
Selection starts with three measurements: rod diameter, housing bore diameter, and groove width. The RGRW mounts in an open groove and its lip seals against the rod. Inspect the rod surface as well; scratches or heavy wear shorten seal life. During installation, lubricate the lip with the system fluid and avoid twisting. Cylinder alignment and adequate lubrication also influence how long the seal lasts.
SKF hydraulic seals can be exchanged with other brands when dimensions and materials match, but codes are not universal. Each manufacturer sets its own nomenclature, so visual similarity is not enough. Compare critical dimensions and service conditions such as pressure, temperature, and speed. If anything is unclear, share your equipment data and we will help you confirm the reference.

Frequently asked questions
- How do I identify the RGRW seal I need?
- Find the full part number on the seal or in the equipment manual. If it is not available, measure the rod diameter, housing bore diameter, and groove width. With those dimensions we can help you locate the equivalent reference.
- What distinguishes an RGRW seal from other seals?
- The RGRW is a rod lip seal intended for hydraulic reciprocating motion. Other seals may be designed for rotating shafts or different pressure ranges. Lip geometry and material define its specific application.
- Can I use another brand instead of SKF?
- Yes, provided the dimensions and material suit your application. Do not rely on the code alone, because each manufacturer uses its own nomenclature. Always compare critical dimensions and the pressure and temperature conditions.
