Oil seal materials

An oil seal, also known as crankshaft retainer, is a small device, but essential to ensure the proper engine operation. It plays a key role in all moving parts of an engine, acting as a physical barrier. This mechanical seal fulfils the dual purpose of sealing a rotary shaft to maintain the necessary lubrication (avoiding leaks) and preventing other foreign matter from contaminating shafts and bearings in the rotary shaft equipment.

Lubricate the threads of the shaft: The o-ring can easily tear during installation as it consists of threading. But this can be avoided by covering the threads with lubricant or masking tape.
