Q: What is the part number of this piston rod seal we are checking?
A: This piston rod seal carries part number 6J-1700, made for motor grader steering cylinder sealing duties.

Q: Which construction machine is seal 6J-1700 suitable for mounting?
A: Seal 6J-1700 is for motor grader, fitted on the steering hydraulic cylinder piston rod.

Q: What raw material forms this piston rod seal?
A: It is produced from nitrile rubber, with good oil compatibility and stable resilience after repeated compression.

Q: What main sealing purpose does this rod seal serve in the steering circuit?
A: It holds hydraulic pressure to keep steering response steady and blocks fine road dust from entering the cylinder.

Q: Where is this piston rod seal located within the cylinder assembly?
A: It is installed inside the cylinder head gland and makes contact with the piston rod during steering travel.

Q: How does this seal perform with frequent steering adjustments on uneven road surfaces?
A: It maintains flexible lip contact and will not easily lose sealing force under continuous small stroke movements.

Q: What hydraulic oil can be used with this nitrile rubber piston rod seal?
A: It matches standard anti-wear hydraulic oil widely adopted for road grader steering systems.

Q: What warning signs show that this piston rod seal needs replacement?
A: Slow steering response and oil seepage on the rod when the grader turns left or right are typical signs.
