The OIL SEAL LIP OPENING PRESSURE TEST RIG(LOP) is manufactured to comply with the SAE: J946 standard of testing.
The LOP test rig is used to test Oil Seals with the Air Flow method. The Rig measures the resistance offered to specified air flow of 10,000 cc/minute between Oil Seal Lip and Mating shaft in static condition. This resistance is due to radial load of lip on shaft and is defined as Lip Opening Pressure (LOP)
The major factors playing a role in LOP are:
Lip Diameter size variation.
Lip Diameter Ovality, Crookedness and localized defects/deformation
Improper Spring load on Lip
Eccentricity of Lip with respect to Outside Diameter
Contact line height
Flex section thickness variation
Radial Wall variation.
MACHINE CAPAITY :
The machine is designed to test Oil Seals with outside diameters ranging upto 300mm with dedicated mating shafts/mandrels as per Oil Seal dimensions.
