VC type single lip rotary oil seal with various materials available
Type VC single-lip seals are a common mechanical sealing element used to prevent the leakage of lubricants, fluids or grease while preventing external dust, dirt or moisture from entering the equipment.
Type VC oil seals have a single lip design, which makes them economical and effective in some applications. The rubberized outer, fully encapsulated inner, single main lip, non-spring loaded type is a rotary seal. Depending on the medium, pressure and temperature, different materials are used. Common materials include NBR VC type skeleton oil seal, Viton VC type skeleton oil seal, Silicone Rubber VC type skeleton oil seal, and so on.
1. Structure and Composition
Sealing lip: made of elastic material such as rubber, Viton, etc. The sealing lip is in direct contact with the rotating shaft or other moving parts to realize the sealing effect in the work of oil seal. Single lip design means that the oil seal has only one sealing lip.
Skeleton: The skeleton provides structural support for the oil seal, enhancing its mechanical strength and stability. The skeleton helps the seal to maintain its shape and avoid deformation.
Design: The design of Type VC oil seals may include additional features such as dust shields or special lip shapes to improve sealing performance. Specific designs will vary according to application requirements.
2. Features
Single Lip Design: With single lip design, the structure of the oil seal is relatively simple and suitable for applications where the sealing requirements are not particularly high. Although the single-lip design is not as comprehensive as the double-lip oil seal in sealing performance, its cost is lower and maintenance is simple.
Sealing Effectiveness: The single-lip design combines the right materials and manufacturing processes to provide a good seal for low to medium pressure applications.
Dust protection: Some Type VC seal designs include additional dust protection, which prevents dirt and particles from entering the sealing area, thereby extending the life of the seal.
