Description
Frame oil seal is a sealing element commonly used in sealing applications such as hydraulic systems and mechanical equipment. It has a structure supported by a metal frame. Its main function is to prevent oil leakage and prevent external pollutants such as water and dust from entering the mechanical system to ensure the normal operation of the equipment. Frame oil seals are usually composed of a metal frame, a rubber sealing lip and an oil return groove. The metal frame gives the oil seal sufficient mechanical strength and pressure resistance, enabling it to operate stably under high pressure, high speed and extreme working conditions. It is widely used in automobiles, engineering machinery, industrial equipment and other fields.

Production
Process
Metal frame manufacturing
The oil seal frame is made of high-strength metal materials (such as stainless steel, carbon steel, etc.) to ensure its stability and strength under high pressure and high load environments.
Rubber molding
Through injection molding or pressing process, suitable rubber materials (such as NBR, FKM, etc.) are processed into sealing lips to ensure the sealing effect.
Vulcanization
The vulcanization process improves the rubber's oil resistance, high temperature resistance, wear resistance, and aging resistance, ensuring long-term and stable operation of the oil seal.
Finishing and assembly
The sealing lip, metal frame and oil return groove are processed precisely to ensure the sealing effect and installation accuracy.
Quality Inspection
Each oil seal is strictly tested for quality, including temperature resistance, pressure resistance, sealing, wear resistance, etc., to ensure compliance with standards.
Packaging and delivery
After strict inspection, the products are packaged to ensure safety during transportation.
Standard frame oil seal
Applicable to sealing under normal working conditions, providing basic sealing effect
Double lip frame oil seal
Designed with double sealing lips to enhance sealing effect, prevent oil leakage and block external contaminants from entering
High temperature frame oil seal
Made of high temperature resistant materials, suitable for sealing requirements in high temperature environments
Customized frame oil seal
Customize size, material, sealing lip design, etc. according to customer needs to adapt to different working conditions and equipment requirements
type
Application
Scenario
Used for sealing of automobile drive shafts, wheels, differentials and other parts to prevent oil leakage and protect internal systems
Such as the sealing of gear boxes, hydraulic pumps, compressors and other equipment to ensure that lubricating oil does not leak
Such as drive shaft seals for excavators, bulldozers and other equipment to protect transmission systems and bearings
Used for ship gearbox and transmission shaft seals to retain oil and prevent external pollutants from entering
Sealing systems for equipment such as tractors and harvesters
Such as the sealing of mining vehicles and mining equipment to ensure the normal operation of the equipment
Features
The frame oil seal is supported by a metal frame to ensure that the oil seal does not deform under high pressure, high speed and high load environment and can effectively withstand pressure.
The rubber lip of the oil seal is reasonably designed to provide a stable sealing effect, effectively preventing oil leakage and preventing external contaminants from entering.
The high temperature resistant rubber material is used to adapt to the high temperature working environment and ensure long-term stable operation under high temperature conditions.
The rubber sealing lip has strong wear resistance, suitable for long-term work and reduces wear.
Made of high-quality rubber material, it has good anti-aging properties and can resist the influence of environmental factors such as ultraviolet rays and oxidation.
Some models adopt double lip design to enhance the sealing effect, prevent oil leakage and improve sealing performance.
It is suitable for various fields such as various hydraulic equipment, automobiles, engineering machinery, mining equipment, etc. and has wide adaptability.
The oil seal has a simple design and convenient installation process, which reduces the maintenance cost of the equipment.
