Description:

The concept of box oil seal:Box oil seal also known as cassette oil seal
Box oil seal is a sealing element used in industrial production to protect equipment from external environments such as dust, moisture, corrosion, etc. Its main function is to isolate grease or lubricating oil in the equipment, which not only reduces the heat generated by equipment friction, but also protects the service life of equipment bearings and other parts. Box oil seals are widely used in various mechanical equipment, industrial machines, agricultural machinery, ships, automobiles and other fields.
The characteristics of the box oil seal are good sealing performance, long service life, simple structure, and easy installation and replacement. According to their different structures and uses, they can be divided into many types of oil seals. Let’s introduce them one by one below.

Classification of box oil seals:
1. Fixed box oil seal
The main function of the fixed box oil seal is to isolate the space between different adjacent parts to prevent foreign matter from entering. Common fixed oil seals have 4 diameters: 10mm, 12mm, 15mm, and 20mm.
2. Adjustable box oil seal
Adjustable box oil seals are mainly used in equipment that require adjustment in size and sealing, such as bearings, pumps and other high-speed mechanical equipment. The adjustable oil seal has an inner conical surface that can be adjusted to suit different sizes to ensure stable and reliable sealing effect.

The concept of combined oil seal:
The combined oil seal is also a seal, consisting of an inner ring, an outer ring, a sealing lip and other parts. It is not only suitable for axial movement, but also for radial movement.

Structural form of combined oil seal:
The structure of the combined oil seal is relatively complex and consists of multiple components such as an inner ring, an outer ring, and a sealing lip. There is a layer of elastic material sandwiched between the inner ring and the outer ring of the combined oil seal, which acts as a seal, and the outer surface is pressed against the outer ring to ensure contact between the sealing lip and the moving parts.

Application range of box oil seals and combined oil seals：
1. Cassette oil seals have a wide range of uses and are suitable for equipment such as wheel axles, reducers, and agricultural machinery.
2. Due to its complex structure, the combined oil seal has a relatively high cost in the production process, so it is generally suitable for high-end mechanical equipment.

Sealing effect of box oil seal and combined oil seal：
1. The density of the sealing lip in contact with the shaft of the cassette oil seal is higher and the sealing effect is better.
2. The combined oil seal has better wear resistance and corrosion resistance, can adapt to more complex environments, and the sealing effect is better than the box oil seal.
