Heavy-Duty Box-Type Cassette Oil Seal

Engineered for heavy-duty applications like axle hubs and drive shafts, this all-in-one Cassette Oil Seal eliminates the need for hardened/ground shaft surfaces, reduces maintenance costs, and effectively blocks mud, dust, and contaminants while ensuring long service life.

BRONZE FILLED PTFE-Sealed GSZ Composite Dust Seal

The GSZ Combined Dust Seal features a high-performance BRONZE FILLED PTFE sealing ring, delivering exceptional wear resistance, thermal conductivity, and dust-scraping efficiency—ideal for hydraulic, pneumatic systems, and servo equipment operating in severe dust or low-temperature environments.

GSJ-W Heavy-Duty Piston Rod Steck Seal

Designed for high-pressure, heavy-load reciprocating hydraulic systems (e.g., bulldozers, forging presses), the GSJ-W Steck seal combines a durable bronze-filled PTFE sealing element with NBR/FKM/PU elastomers, ensuring low friction, stable sealing, and long service life.

GSF-W Series Heavy-Duty Bore Glyd Ring for High-Pressure Hydraulic Systems

The heavy-duty bore Glyd Ring GSF-W is a high-performance hydraulic piston seal, featuring a filled PTFE main ring paired with optional NBR, FKM, or PU O-rings to deliver excellent dynamic/static sealing, low friction, and resistance to high pressure, making it ideal for heavy machinery like injection molding machines and construction equipment.

GSD-W Heavy-Duty Reverse Step Seal

Designed to withstand high-impact hydraulic conditions, the GSD-W Heavy-Duty Reverse Step Seal features NBR/PU sealing elements that provide reliable wear compensation, making it a durable choice for hydraulic pistons, cylinders, and critical components in industrial and construction equipment.

GSD Type Piston Seal for Hydraulic Systems

The GSD bore seal is a high-performance double-acting sealing element specifically designed for reciprocating pistons in hydraulic systems, featuring a core structure of bronze-filled PTFE (F-PTFE) ring paired with an NBR or FKM elastomer O-ring.

Forever Seals DAQ2 Low - Friction Hydraulic Seal - Reliable Leakage Control

Forever Seals DAQ2 hydraulic seals integrate dual wear rings and a star - shaped elastomer. They ensure bidirectional sealing, handle 40MPa pressure, and resist - 45℃~+200℃ temps for stable hydraulic system ops.

Industrial DAQ Sealing Solutions for Press Machinery

DAQ seals, featuring a star - shaped combined structure with elastomers and wear - resistant rings, ensure bidirectional sealing, low friction, and high pressure resistance (up to 40MPa) for hydraulic cylinders and industrial machinery.

NBR VA Seal: Ideal for Medium-Temp Applications

Forever Seals' VA NBR seal, with excellent oil resistance and flexibility, delivers reliable sealing for industrial hydraulic systems and fuel applications.

KR - Type Piston Seals for Hydraulic Cylinders

KR - type seals deliver reliable, low - leakage performance in high - pressure hydraulic systems, with self - tightening V - structure and wear compensation for long - term sealing integrity.

FKM VA Seal: Reliable Sealing Solution

Industrial - grade FKM VA seal. Temp range (-20℃ to 200℃), oil - resistant. Easy - install, long - lasting sealing for systems.

R35 Heavy-Duty Oil Seal: Anti-Leak, Wear-Resistant, FKM/NBR

R35 heavy-duty oil seal, made of FKM/NBR, offers anti-leakage and wear resistance, ideal for rolling mills, wind power and heavy machinery. Its fabric-reinforced structure with spring-loaded lips ensures consistent sealing pressure even in high-stress industrial operations.

We have specialized in the development and production of high-quality sealing products, including O-rings, hydraulic seals, pneumatic seals, and oil seals.
