China Oil Seal Size
Product Details: China oil seals are mechanical components used to seal oil and other fluids in various mechanical systems. They are typically made from materials such as NBR, FKM, PTFE, PU, and silicone. These seals are designed for static and dynamic sealing applications, including reciprocating motion. Key types include TCY oil seals, which are double-lip oil seals with a self-tightening spring fully covered by rubber. They are used in applications like excavators, loaders, graders, dump trucks, forklifts, and other construction and automotive machinery. The seals come in standard and customized sizes and are designed to handle high temperatures, low temperatures, high pressure,
and low pressure, as well as friction resistance[1][2][4].
Pros:
– Better sealing performance and reduced leakage problems
– Less friction and lower energy consumption

Oil Seal – YALAN Seals – China Mechanical Seal Standard …
Product Details: The oil seal, also known as the floating oil seal, is an alternative to the traditional framework oil seal. It is assembled with a metal framework and an NBR outer ring. The seal is designed to close spaces between stationary and moving components in mechanical equipment, preventing lubricant escape and stopping harmful contaminants from entering the machinery. It features two floating rings combined with O-rings, which act as both sealing and compensation components to ensure the seal faces stick together closely. The O-rings do not have direct contact with the shaft, preventing damage. The seal has a compact and simple
structure, is easy to install, and has a long lifespan. It is made from materials such as Chrome-Molybdenum Steel/TC and NBR/HNBR/VMQ/FPM. The seal operates within parameters of ≤ 2.0 MPa pressure, -50°C to 200°C temperature, and ≤ 10 m/s linear speed. It is used in construction, mining, farm, building, and environmental machinery.
Pros:
– Compact and simple structure, easy to install
– Long lifespan and maintenance-free
– Better sealing effects than normal elastomer shaft seals
– Wide range of applications including coal cutters, tramcars, and other machinery
– Customizable materials for different operating parameters
