Product
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

07.

Features

High strength metal frame

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.

Excellent sealing

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.

High temperature resistance

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.

Strong wear resistance

The rubber sealing lip has strong wear resistance, suitable for long-term work and reduces wear.

Resistance to aging

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.

Lips design

Some models adopt double lip design to enhance the sealing effect, prevent oil leakage and improve sealing performance.

Wide applicability

It is suitable for various fields such as various hydraulic equipment, automobiles, engineering machinery, mining equipment, etc. and has wide adaptability.

Easy installation

The oil seal has a simple design and convenient installation process, which reduces the maintenance cost of the equipment.
