How to measure the diameter of floating seals?

Measuring the precise dimensions of floating seals is crucial as it directly impacts the effectiveness of sealing and operational efficiency of the equipment. By implementing scientifically dimension management and maintenance measures, the equipment’s lifespan can be effectively extended, production efficiency enhanced, and maintenance costs reduced.


What dimensions do we need when purchasing floating seals?


The outer and inner diameters of floating seals are determined based on the dimensions of the seal chamber and the size of the rotating shaft or bearings, while the thickness depends on the axial space provided by the seal chamber. Therefore, it is essential to comprehensively consider the matching relationships among the seal chamber dimensions, the dimensions of the rotating shaft, and the dimensions of the bearings when designing the floating seals to ensure its sealing and wear resistance.

Additionally, optimizing the material selection and manufacturing processes of the floating seals is crucial for improving its performance and lifespan. Thus, various factors need to be taken into account when designing the floating seals, including selecting the product dimensions, the most suitable materials for specific operating conditions, and manufacturing processes to ensure its stable and reliable operation in different environments.

Four most important diameters of floating seals are metal seal ring diameter (D), inner diameter (ID), outer diameter (OD), and the thickness (H)


Following are the diameter drawings of duo cone seals and heavy duty seals.



Following shows the measurement method of the floating seals:

① Metal seal ring diameter (D)



② Inner diameter (ID)




③ The thickness (H): usually two metal seal rings’thickness




④ The outer diameter of the floating seals (OD)
