Description

DEDE Seal Co., Ltd. is one of the most reliable manufacturers and suppliers of tg4 oil seal in China. If you're going to buy bulk tg4 oil seal made in China, welcome to get pricelist from our factory. All customized seals are with high quality and competitive price.

 

The TG4 Oil Seal is an upgraded rotary shaft sealing component engineered for heavy-duty harsh working environments where standard single or double-lip seals fail to deliver adequate protection. Its optimized triple-lip sealing architecture effectively locks internal lubricants and fully blocks external dust, mud and moisture from invading the sealing zone. It is the ideal sealing solution for equipment that demands extended service cycles and lower maintenance frequency.

 

Product Benefits

 

 

Optimized triple-lip construction delivers more stable sealing performance than ordinary oil seals, greatly slowing premature lip abrasion

 

Strong lubricant retention capability, ensures smooth equipment operation and extends the service life of gears, bearings and other core parts

 

Outstanding adaptability for equipment with frequent start-stop cycles, continuous vibration and heavy contamination exposure

 

Outer threaded design improves fitting tightness, prevents external seepage caused by thermal expansion of housing parts

 

Material Options

 

 

DEDE supplies TG4 oil seals with two standard elastomer materials, custom compound formulas are available upon request: 

NBR Nitrile Rubber

Matches mineral oil, grease and all common general industrial equipment

FKM Fluoroelastomer

Recommended for high-temperature operation and working media requiring superior chemical corrosion resistance

 

Typical Applications

 

 

The Seals are widely deployed on all heavy rotary machinery:

● Industrial gearboxes & speed reducers

● Agricultural machinery: tractors, harvesters, farm attachments

● Construction equipment: excavators, loaders, road rollers

● General & servo electric motors

● Hydraulic pumps, water pumps & oil pumps

● Heavy-duty transmission & robotic arm systems

FAQ

 

 

Q1: What is the difference between TG4 Oil Seal and ordinary triple-lip oil seal?

A: The core difference lies in the outer thread locking structure. Ordinary triple-lip oil seals only optimize internal sealing with smooth outer rings, which are prone to loosening and oil leakage under high vibration. TG4 adopts threaded line-contact locking design for the outer ring with stronger fitting tightness. Combined with triple-lip protection and dual oil chamber structure, it achieves far better stability in heavy vibration and harsh environments.

Q2: What are the core advantageous scenarios of TG4 Oil Seal?

A: It is specially designed for high-vibration, muddy-dusty, frequent start-stop and all-weather outdoor heavy-duty working conditions. It solves common defects of ordinary oil seals such as seal displacement, outer ring leakage and rapid lip wear, which is the preferred upgraded sealing solution for harsh industrial scenarios.

Q3: Does the threaded outer ring increase installation difficulty?

A: No.it follows standard press-fit dimensions without hole modification or special tooling. The threaded structure only enhances locking tightness after installation without changing assembly specifications, supporting direct replacement of ordinary oil seals of the same size.
