Product Description


L-shaped Type Floating Oil Seal


Product Description:

Floating seals are seals used in harsh environments such as undercarriage equipment for construction machinery and agricultural machinery. A seal product consisting of a special metal ring that is resistant to wear and an O-ring / packing made of rubber. By sliding the metal seal surface at the bearing, lubricating oil inside the equipment and intrusion of muddy water, earth and sand from the outside, etc. To prevent. A pair of the same shape is combined, and when the O-ring packing is deformed, the metal seal part is moved to the center of the groove and floats with respect to the shaft, so it is called a floating seal.

Floating Seal Structure:

  • There are two types of floating seals, one is a general type that uses an O-ring, and the other is a special type that uses a rubber product with a diamond-shaped cross section instead of the O-ring. Both types consist of two metal rings with the sealing surfaces polished to each other.
  • A pair of these two metal rings are incorporated into separate housings so that the sealing surfaces are in contact with each other, and the O-rings combined with the outer peripheral surface serve to position the entire seal in the center of the housing and perform the sealing function. ..
  • The housing shape is usually machined on an NC lathe.

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:

1. Have certain mechanical properties, such as tensile strength, elongation, etc.;

2. Appropriate elasticity and hardness, small compression set;

3. High temperature and low temperature resistance, no decomposition or softening at high temperature, and no hardening at low temperature;

4. It is compatible with the working medium, without swelling, decomposition, hardening, etc.;

5. Good oxygen resistance and aging resistance, durable;

6. Abrasion resistance, no corrosion to metal;

7. Easy to shape and process, low price.
