The DTW-J2G line from SKF covers lip seals built for hydraulic cylinder rods. Their job is to hold pressurized fluid on one side and keep dirt, water and other contaminants out, which protects the rest of the system and keeps it running efficiently. You will find them on mobile equipment, presses, construction machines and industrial circuits that run on mineral oil or hydraulic fluid. MR Industrial Accessories supplies them as part of its sealing range.
Reading the code helps you order the right size. The letters DTW name the series, and what follows points to the rod diameter and the compound. A reference such as DTW-25X33X5-J2G describes a seal for a 25 mm rod, a 33 mm outer diameter and a 5 mm height, in J2G compound. Where the number appears on its own, as in DTW-250-J2G, the 250 stands for a 25.0 mm rod, the letter J marks the elastomer family and the G suffix can signal a design or material variant. Confirm these readings against the SKF catalog before ordering.
Typical installations include excavator and backhoe cylinders, cranes, presses, mining equipment and farm machinery, along with lifting systems, power steering and hydrostatic drives. Repair shops that service road machinery, steel plants and offshore operations also use this series. It suits moderate to high pressures and the rod speeds normally seen in linear motion.
Selection comes down to three dimensions: rod diameter, outer diameter and housing height. The J2G compound is generally a polyurethane, chosen for abrasion and extrusion resistance. Check that it is compatible with your hydraulic fluid and operating temperature. At installation, keep the rod aligned, avoid nicking the lip, lubricate properly and keep the sealing area clean.
Dimensional equivalents from other recognized seal makers can serve as replacements when size and material line up. Tolerances and lip geometry differ between manufacturers, so it pays to compare technical data first. Our team can review interchangeability and help you source a suitable alternative.

Frequently asked questions
- How do I work out which DTW-J2G seal I need?
- You need three figures: rod diameter, outer diameter and height. DTW-25X33X5-J2G, for instance, is a 25 mm rod, 33 mm outer diameter and 5 mm height. If all you have is the part number, read the digits after DTW as the rod diameter in tenths of a millimeter.
- What is the J2G compound?
- The J2G suffix normally points to a high-strength polyurethane intended for hydraulic service with mineral oils, with good elasticity and abrasion resistance. For special fluids or extreme temperatures, check the manufacturer's data sheet.
- Can another brand's seal replace an SKF DTW-J2G?
- Dimensional equivalents do exist. Match both the dimensions and the compound type, since tolerances and lip design vary from one maker to another and affect performance. We can advise on the most practical option.
