yx sealing ring shaft hole with how to distinguish

YX type sealing ring is divided into two kinds of shaft and hole, which can be distinguished by the following methods:

Distinguish from the tilt Angle of the lip of the largest and smallest diameter sides of the Y-ring: if the tilt Angle of the lip of the largest diameter side is less than the Angle of the smallest diameter side, it is used for the shaft; Conversely, if the tilt Angle of the lip of the largest diameter side is greater than the Angle of the smallest diameter side, it is used for holes. This is because the shaft is sealed by stretching the inner lip, so the tilt Angle of the inner lip is large; The hole is sealed by the compression of the outer lip, so the tilt Angle of the outer lip is larger.

Distinguish by looking at the letters on the seal ring: if the seal ring is marked with "D", it is for holes; If marked with "d", it is used for axes.

In addition, the specific uses of the YX sealing ring shaft and hole are also different. The YX sealing ring for the shaft is mainly used to seal or fix the sliding shaft surface, while the YX sealing ring for the hole is mainly used to seal the sliding inner hole surface.

Please note that when installing the YX sealing ring, it is necessary to carefully check the lip edge and lip quality, and set the groove size according to the relevant requirements, and try to select the sealing ring with proper porosity and reasonable materials for installation to ensure its sealing effect and working stability.
