The SKF PA series covers single-lip seals built for hydraulic cylinder rods. Their job is to hold pressurized fluid in and keep contaminants out, which protects the system and keeps it running efficiently. You will find them on mobile equipment, presses, agricultural machinery and general industrial plant. MR Industrial Accessories LLC supplies this line and helps you match the size to your cylinder.
Reading the code takes a moment once you know the layout. The letters point to the family, and the numbers behind them give the dimensions in millimeters. Take PA 20X30X7X10: rod side 20 mm, housing side 30 mm, overall height 7 mm, lip height 10 mm. The same logic applies to PA 25X35X7X10, PA 30X40X7X10 and every other size in the range, so a replacement can be pinned down without guesswork.
Typical applications include hydraulic cylinders on road machinery, earthmoving equipment, presses, cranes and agricultural systems, plus metallurgical, plastics and construction operations where a rod has to seal oil across a range of pressures. These are common in cylinder repair work, where dependable sealing is what keeps leaks and early wear away.
Before ordering, confirm three things: rod diameter, housing diameter and the height you have to work with. The PA series tolerates a certain amount in assembly, but the rod surface has to be ground and free of burrs. Lubricating with the same oil the system runs on eases installation and protects the lip. Check as well that the spring sits where it should and that the seal is not cocked in the cavity.
Because hydraulic seals are defined by dimensions and lip type, units from different brands can be swapped when size and material line up. SKF is a global reference, and other options exist. Our team can point you to the choice that suits your application without hurting hydraulic performance.

Frequently asked questions
- How do I work out which PA seal I need?
- Take the rod diameter, the housing diameter and the height. PA references run inner diameter x outer diameter x overall height x lip height, all in millimeters. With those figures we can confirm the exact reference.
- Can SKF PA series seals be used in place of other makes?
- Yes, provided the dimensions and lip type agree. Interchangeability comes down to size and seal material. Send us your part number and we will list the matching options.
- What should I watch for during installation?
- Clean the housing, check the rod for burrs and lubricate the lip before you push it in. Do not let the seal twist, and make sure the spring is seated correctly. Careful fitting helps the seal last.
