5. FAQ

Q: What are the material characteristics and why are they chosen for motor grader working conditions?
A: Motor graders operate in harsh environments with heavy dust, high pressure, and frequent load changes. NBR offers excellent oil resistance and elasticity, adapting to mineral hydraulic oils. PU buffer seal absorbs pressure shocks, protecting the main seal from damage during frequent blade adjustments. FKM O-rings provide high temperature and aging resistance, suitable for long-hour operation. PTFE wear rings reduce friction between metal parts, lowering wear and noise. This composite material design ensures stable sealing, long service life, and reliable performance in tough conditions.


Q: Can you describe the color, appearance and structural features of the seal components?
A: Each component has unique features. The NBR main seal is black with a double-lip design, smooth outer surface, and fabric-reinforced inner core for durability. The PU buffer seal is orange, with a tapered profile to cushion pressure spikes. The NBR piston seal is black, U-shaped with anti-extrusion notches. FKM O-rings are brown, glossy, with uniform cross-section. PTFE wear rings are white, flat, rectangular with precision grooves. PA66 backup rings are beige, rigid, circular. The dust wiper is black with an outward lip to block dirt. All parts have precise dimensions and smooth edges for perfect fit.


Q: What are the key technical parameters like pressure rating, temperature range and service life?
A: This heavy-duty seal kit is built for motor grader hydraulic systems. Max working pressure: 380 bar, suitable for high-pressure hydraulic circuits. Operating temperature: -30°C to +120°C, covering cold winter and hot summer conditions. Service life: Under normal medium-load conditions (≤280 bar, 40–80°C), it reaches 6000–8000 working hours. In harsh environments (heavy dust, frequent impacts, continuous high temperature), it still achieves 4000–5000 working hours, 50–70% longer than standard single-material kits.


Q: What common problems do low-quality seal kits have, and how does 238-25-16360 solve these issues?
A: Low-quality kits often use recycled rubber or inferior materials, leading to oil leakage due to poor lip precision or material shrinkage. Under high pressure, seals may extrude, crack or twist, causing sudden cylinder failure. Inferior O-rings harden and become brittle, losing sealing ability. Low-grade PTFE wear rings wear quickly, leading to metal contact and cylinder damage. In contrast, 238-25-16360 uses 100% virgin materials with strict QC. Precision-machined double-lip seals ensure tight sealing. PA66 backup rings prevent extrusion. High-quality FKM resists aging, and pure PTFE reduces friction. These features eliminate common failures, reduce maintenance frequency, and lower long-term costs.


Q: What installation steps and precautions should be followed to ensure optimal performance?
A: Proper installation is critical. First, disassemble the cylinder completely and clean all parts (grooves, rod, bore) with clean hydraulic oil—remove all old seal debris, metal shavings, and dirt; even tiny particles can damage new seals. Second, inspect the piston rod and bore for scratches, dents, or corrosion; repair or replace damaged parts. Third, lubricate all new seals and O-rings with clean hydraulic oil; never use grease, as it causes rubber swelling. Fourth, install seals in the correct orientation (rod seal lip faces pressure side; piston seal open side faces piston head); use proper tools to avoid twisting. Fifth, fit wear rings and backup rings tightly into grooves with no gaps. Finally, test at low pressure first after assembly to check for smooth movement and leaks before full-pressure operation.
