General
The compact rod seal Profile Q2R is a combination of a fabric-reinforced grooved ring (high extrusion resistance) and a vulcanised rubber sealing part (high sealing effect). The sealing edges of the rubber part are radially pre-stressed during installation and thus wipe off the liquid film on the rod most effectively. As a result, this seal has an excellent sealing effect even in the low-pressure range and in a depressurised state.
Medium
Hydraulic fluids based on mineral oil, water and water-glycol emulsions
Material
Standard materials: NBR or FKM elastomers with hard fabric insert
Advantages
- due to its robust design, the Q2R can be used in rough operating conditions
- easily adjustable to operating conditions via selection of different materials.
- High sealing and wiping effect
- Hydrolysis-resistant
Installation instructions
Due to its small profile width, the U-Cup is sensitive to tolerance deviations and excessive tolerance clearance between piston and guide unit.
Range of application
Hydraulic cylinder piston rods, plungers, slides, plungers
