Oil seals, often referred to as shaft seals or rotary seals, play an essential role in various industrial applications. Among the diverse types of oil seals in the market, the oil seal designated as 20% 35% 7% specifically represents a particular sizing and design that can address unique sealing requirements. In this article, we will explore the significance of oil seals, the specific features of the 20% 35% 7% oil seal, and its applications.

Types of Hydraulic Shaft Seals

5. Backup Rings These rings are used in conjunction with O-rings to prevent extrusion under high pressure, providing additional protection to the sealing system.

4. Follow Torque Specifications When reassembling the pump, adhere to the manufacturer’s torque specifications to avoid damaging the seals or the pump itself.

When it comes to selecting cylinder seal kits, it is essential to consider several factors. First, one must be aware of the specific size and type of cylinders in use. The seal kits should be correctly matched to the machinery’s specifications to ensure proper fit and function. Additionally, the material of the seals is crucial. Different hydraulic fluids may require seals made from various materials to resist degradation and maintain performance under varying pressure and temperature conditions.

- O-Ring Seals Circular in shape, O-rings are widely used due to their simplicity and effectiveness. They can accommodate a range of applications and are often used in low-pressure systems.

Conclusion

Oil seal companies specialize in producing seals that cater to a wide range of applications, including automotive, aerospace, heavy machinery, and consumer appliances. These companies focus on developing seals that can operate in extreme conditions, resist wear, and withstand the pressure and temperature fluctuations common in industrial settings. The innovation seen in oil seal design includes the use of various materials—such as rubber, silicone, and polyurethane—to enhance durability and performance.

   - Shut down the system: Before beginning the replacement procedure, ensure that the system is safely shut down to prevent accidents and injuries.

4. Shaft seals These seals prevent fluid from leaking along the shaft of the pump. They play a vital role in protecting the pump from contamination and maintaining the hydraulic fluid’s integrity.
