Good Wear Resistance PTFE Rotary Seal Ring Gns for High Speed Cylinder
This high-performance PTFE Rotary Seal Gns is engineered for high-speed cylinder applications. Delivering exceptional wear resistance under heavy duty conditions, it efficiently handles pressures up to 30MPa and temperatures from -30°C to +200°C. It is the ideal Rotary Seal solution for reliable, leak-free performance in demanding hydraulic systems.
1. Performance and use
rotary seal ring is suitable for rods, shafts, pins, rotary joints, etc. that rotate in the circumferential direction or angle. It is a two-way rotating sealing ring that can withstand pressure on both sides or alternating pressure. It is used in construction machinery, manipulators and automobiles, etc. industrial field,
Small friction, no sticking phenomenon, smooth start, no crawling even at low speed.
The groove is simple and the cross-sectional size is small
Good wear resistance, dimensionally stable
Very good compatibility with hydraulic media
High temperature resistance, good extrusion resistance
While rotating, it can withstand certain reciprocating motion.
2. Materials
Sealing slip ring: filled with polytetrafluoroethylene (PTFE). According to different working conditions and sealing requirements, different filling materials and filling processes can be selected, please contact us for details.
O-ring: NBR (nitrile rubber) or FKM (fluororubber), determined according to specific working conditions, the default is NBR, for special working conditions, please inquire and explain before ordering.
3. Labeling method
Mark with the size of the installation groove. The marking method is:
GNS "nominal diameter size D" × "groove bottom diameter d" × "groove width L"
4. Precautions:
Ⅰ. Pay attention to the external dust protection. If necessary, please install the corresponding dust ring.
Ⅱ, There may be one or two sealing grooves, which are designed according to working conditions and user requirements.
Ⅲ, If the installation space permits, please choose a seal with a larger cross-section to increase the seal life and reliability, but the installation will be more difficult.
