Having problems installing oil seals? The part has had many updates in recent years, which has totally changed the installation process. In this blog, our specialists will give you information and installation tips so that these oil seals no longer cause difficulties during your overhaul or repair job.

The metal case serves as the oil seal’s exterior or frame, providing rigidity and strength to the seal. The case material selection depends on the environment in which the seal will operate. Often, the same rubber material used in the seal element covers the case to help seal the exterior of the oil seal in the housing bore.

Because the inner diameter of the oil seal must be stretched during assembly, it is necessary for the shaft to possess a ramped edge. The angle at which the ramped taper should be chamfered is 30° a 50°. If a flange or keyway is present on the shaft, it is best to use a bushing. The bore should also have a chamfer of 30° over at least 1 mm on the ramped side. Be sure to round off the edges properly in the process.

This technique is used when the seal depth must match the housing surface precisely. It involves stopping the installation tool at the machined housing face. Ensure the tool is perfectly perpendicular to the shaft for best results. This technique is ideal for applications requiring exact seal positioning relative to the housing face.

Temperature

Fluid side face The front-end face of the seal is called the nose. The nose is made of rubber and forms a gasket seal when compressed on the housing shoulder.

Pressure - Many oil seals can only withstand low-pressure applications, so understanding the compression set of your components is key.

Description
Heavy Duty Wheel Seals and Agricultural Equipment Seals can be divided into AP type, CRS type and ST type. Mainly be used in heavy pollution of agricultural machinery, construction machinery, mining equipment and trucks, buses and other environments. Compared to TC type, with special internal lubrication design, making it closed to the rotary shaft seal and bearing assembly which prevent external dirt effectively; a specially designed multi-lip inside the seal, makes it to achieve the function. Multiple external sealing lip design effectively prevents outside dirt and grease leakage immersion; the internal high-quality grease (butter) prevents muddy and water immersion.
