The TG4 skeleton oil seal is an advanced sealing solution featuring external circular threads and 3 built-in lips, delivering superior anti-leakage (both internal and external) and dust-proof performance, widely suitable for industrial machinery, automotive systems, and hydraulic equipment.
Engineered for automotive, manufacturing, and heavy-duty industrial machinery, this Rotary Seal ROI features a low friction coefficient and durable PU construction, effectively preventing fluid or gas leakage in high-pressure rotating applications while boasting an extended service life.
The Pneumatic Sealing DK Buffer-Type Integral Piston integrates sealing and guiding functions, featuring a double U-seal and metal skeleton bonded structure. It is rubber-coated for corrosion resistance, compatible with oil-lubricated and initially lubricated oil-free air, and operates smoothly with low friction.
The HBY combined buffer polyurethane seal ring is a high-performance sealing solution tailored for construction machinery and hydraulic equipment, integrating a polyurethane seal ring with POM/PA backup rings to deliver exceptional pressure resistance (up to 50MPa) and wear resistance.
This high-performance COMBI combination oil seal features a polyurethane (PU) dust lip, delivering exceptional resistance to external contaminants like dust, dirt, and debris while reliably preventing internal oil leakage, making it ideal for harsh working environments.
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.
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.
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.
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.
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.
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 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.
