Product Description

Product Description

The TG4 oil seal is a multi-lip, high-performance rotary shaft seal designed for demanding industrial and automotive applications. Its reinforced structure and premium elastomer materials provide reliable sealing under high pressure, high temperature, heavy contamination, and continuous dynamic operation.

Key Features

Multi-lip sealing structure — Offers enhanced oil retention and superior dust exclusion, ideal for harsh working environments.

Reinforced metal skeleton — Ensures excellent rigidity, stable installation, and long-term durability.

High-grade elastomer materials — Available in NBR, FKM, compatible with oils, lubricants, water-based fluids, and chemical media.

Low friction design — Reduces heat generation and wear during high-speed rotation.

Excellent pressure resistance — Suitable for hydraulic systems and heavy-load machinery.

Functions

Prevents lubricant leakage in rotating shafts

Blocks dust, mud, moisture, and contaminants

Maintains system pressure and improves equipment efficiency

Protects bearings and transmission components from wear

Ensures stable operation under continuous dynamic motion

Typical Applications

Industrial machinery: forging machines, reducers, pumps, compressors

Construction equipment: excavators, loaders, tunneling machines

Agricultural & off-road vehicles: tractors, ATVs, harvesters

Automotive systems: engines, transmissions, differentials

Hydraulic & pneumatic equipment operating under high pressure and heavy load

Product Advantages

High temperature resistance (up to 250°C with FKM material)

Superior chemical and corrosion resistance

Enhanced sealing stability in dusty, muddy, or high-pollution environments

Extended service life due to optimized lip geometry and wear-resistant materials

Reliable performance in extreme working conditions with large temperature variations

Interchangeable with international models such as HMSA7, WAS, R23, etc.
