Joint d'étanchéité rotatif GRS à bague en silicone OED pour cylindre OU joint d'étanchéité à gradins pour joint rotatif

The Shaft Rotary Glyd Ring is a double-acting rotary seal designed for rods, shafts, pins, rotary joints, and other components with rotary or oscillating motion. It is widely used in construction machinery, building equipment, automotive equipment, and other industrial hydraulic systems.

The seal consists of a filled PTFE sealing ring and an NBR or FKM O-ring. It can withstand pressure from either side or alternating pressure and is installed in ISO 7425 standard grooves. Single-acting designs are also available for higher rotational speeds. For design reference, the product corresponds to Trelleborg TG3, Merkel M15, Parker OR, and AS XRB series standards.

Caractéristiques principales :

• Suitable for both piston rod and piston sealing applications
• Low friction with no stick-slip or crawling during startup
• Excellent wear resistance and dimensional stability
• Simple, compact groove design with a lubrication cavity
• Available in GRS TG3, M15, OR, and XRB series configurations

Working Conditions for rotary seals

Installation Notes

• Ensure shaft and housing surfaces are clean and free from burrs.
• Lubricate the seal and installation area with a compatible lubricant.
• Avoid twisting the O-ring during installation.
• Protect the PTFE lip from sharp edges.

Installation Dimensions

Muti material for different working applications

Standard Materials

Seal Ring: Filled PTFE (F-PTFE) O-Ring: Nitrile Rubber (NBR) or Fluoroelastomer (FKM)

PTFE Bronze Filled Seal

A PTFE compound with bronze powder for high-pressure, heavy-duty hydraulic sealing. Bronze improves thermal conductivity, load capacity, wear and extrusion resistance. Low friction and good chemical resistance, but may wear softer mating surfaces.

PTFE Carbon Fiber Filled Seal
Carbon fiber filled PTFE seal offers improved wear resistance, creep resistance, thermal conductivity and load-bearing capacity while maintaining low friction. It is suitable for rotary and reciprocating sealing applications under medium to high loads.

PTFE Carbon Fiber + Graphite Filled Seal
Carbon fiber and graphite filled PTFE seal combines good wear resistance with improved self-lubricity and thermal conductivity. It is well suited for dry-running, low-speed and high-PV applications where low friction is critical.

PTFE Carbon Fiber + Glass Fiber Filled Seal
This seal combines carbon fiber and glass fiber in PTFE to provide higher rigidity, dimensional stability, wear resistance and pressure resistance. It is suitable for medium- to high-pressure sealing duties, but may cause slightly higher counterface wear.

Polyurethane Seal
Polyurethane seal features high wear resistance, tear resistance, oil resistance and load-bearing capacity. It is widely used in hydraulic reciprocating seals, but its resistance to hydrolysis and high temperature is relatively limited.

Applications for rotary glyd ring seal

Widely used in seals for hydraulic equipment, automotive, power, new energy, shipbuilding, pharmaceutical equipment, semiconductor, water treatment and sanitary ware, robotics, agricultural machinery, food and beverage, and other industries.
