Product
Description

CR oil seal (chlorinated rubber oil seal) is a sealing element made of chlorinated rubber (CR) material, which is widely used in mechanical equipment, especially for sealing needs in high temperature, high load and harsh environment. CR oil seal has excellent oil resistance, wear resistance, oxidation resistance and aging resistance, which can effectively prevent oil leakage, and prevent external pollutants such as dust and moisture from entering the equipment, thereby protecting the normal operation of the equipment. It is commonly used in transmission shafts, hubs, gear boxes and other parts in automobiles, engineering machinery and industrial equipment to provide long-lasting and reliable sealing effects.

Production
Process

Metal frame manufacturing

Use high-strength metal materials (such as stainless steel or carbon steel) to make the metal frame of the oil seal to provide support for the oil seal.

Rubber molding

The rubber material (such as NBR, FKM, etc.) is processed into a sealing lip through injection molding or pressing technology to ensure the sealing effect.

Vulcanization

The vulcanization process improves the high temperature resistance, oil resistance, and aging resistance of rubber materials, ensuring stability in high temperature and high pressure environments.

Finishing and assembly

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

Quality Inspection

Each oil seal undergoes strict quality testing, including temperature resistance, pressure resistance, sealing, etc., to ensure its stable and reliable performance.

Packaging and delivery

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

Standard TA oil seal

Suitable for sealing conventional equipment, providing stable oil sealing effect

Double lip type TA oil seal

Designed with double sealing lips to increase sealing performance, prevent oil leakage and block external contaminants from entering
