Replacement Oil Seal Kit A2FO125 For REXROTH Hydraulic Pump Service Parts

Basic Requirements For Sealing Materials:

• The performance of the sealing material is an important factor to ensure effective sealing. The selection of the sealing material is mainly based on the working environment of the sealing element, such as the temperature, the working pressure, the working medium used, and the movement mode. The basic requirements for sealing materials are as follows:
• Have certain mechanical properties, such as tensile strength, elongation, etc.;
• Appropriate elasticity and hardness, small compression set;
• High temperature and low temperature resistance, no decomposition or softening at high temperature, and no hardening at low temperature;
• It is compatible with the working medium, without swelling, decomposition, hardening, etc.;
• Good oxygen resistance and aging resistance, durable;
• Abrasion resistance, no corrosion to metal;
• Easy to shape and process, low price.

Advantages Of Oil Seal:

1. Oil seal structure is simple and easy to manufacture. Simple oil seal can be molded in one time, even the most compliC.A.Ted oil seal, the manufacturing process is also oil seal not compliC.A.Ted. The metal skeleton oil seal can also form the required oil seal between metal and rubber only by stamping, gluing, inlaying, molding and other processes.

2. Oil seal has light weight and few consumables. Each type of oil seal is a combination of thin-walled metal parts and rubber parts, and its material consumption is very small, so the weight of each oil seal is very light.

3. The installation position of the oil seal is small, the axial size is small, easy to process, and make the machine compact.

4. Oil seal has good sealing performance and long service life. It has certain adaptability to the vibration of the machine and the eccentricity of the main shaft.

5. Oil seal is easy to disassemble and convenient for inspection.

6. The oil seal is cheap.
