Product
Description

TB oil seal is a sealing element specially used in hydraulic systems, mechanical transmission systems, etc., and is particularly suitable for working conditions with large axial loads. Its design features combine sealing, wear resistance, pressure resistance and other properties to ensure that the oil does not leak during the operation of the system, while effectively preventing external pollutants (such as dust, moisture, etc.) from entering. TB oil seals are widely used in various types of machinery and hydraulic equipment, especially in situations where they need to withstand high pressure, high speed and high axial load. It is usually composed of a metal frame, a rubber sealing lip and an oil return groove. The metal frame increases the strength of the oil seal and ensures its stability under high-load and high-speed working environments.

Production
Process

Metal frame manufacturing

The metal frame of the oil seal is made of high-strength metal materials (such as stainless steel, carbon steel, etc.) through precision processing to ensure its stability under high-load environments.

Rubber molding

The selected rubber material (such as NBR, FKM, etc.) is processed into a sealing lip through injection molding or pressing technology to ensure that the oil seal has excellent sealing performance.

Vulcanization

The vulcanization process is used to improve the oil resistance, high temperature resistance, wear resistance and aging resistance of rubber, so that it can withstand high temperature and high pressure environments.

Finishing and assembly

The sealing lip, metal frame and oil return groove are finely processed to ensure the sealing effect and installation accuracy of the product.

Quality Inspection

Each oil seal is strictly tested for quality, including temperature resistance, pressure resistance, sealing, etc., to ensure the product's performance is stable and reliable.

Packaging and delivery

After passing the quality inspection, the products will be packaged to ensure safety during transportation.
