UHS refers to the UHS type shaft hole universal sealing ring~~There is also the UN type shaft hole universal sealing ring~~25 refers to the nominal diameter~~
“"Universal shaft hole" is what it means - "Universal shaft hole". I looked for an English translator and asked Du Niang. UHS is generally made of polyurethane material. USH is generally made of rubber (fluorine rubber, nitrile rubber) material.
This is what it means in English~~UHS does not limit the material~~For example, NO.2060-UHS is made of nitrile rubber； NO.4060-UHS is fluorine rubber~~
Now I understand that UHS means that the shaft hole is universal. All other materials and sizes are standard.

The above explanation is very clear. UHS is the standard of Japan's Valka. It is a universal seal for shaft holes and is made of polyurethane. USH is the standard of Japan's NOK. It is also a universal seal for shaft holes and is made of nitrile rubber.
