- 2. Cartridge-Type Metal-to-Oil Seal As the name suggests, this type of seal is housed in a cartridge that can be easily installed and replaced. Cartridge-type seals are designed for applications where frequent maintenance is required or where the shaft diameter is too large for face-type seals.

crankshaft oil seal.
Next, apply a small amount of grease to the seal lip(s) and the area of the shaft in contact with the seal. When using a double-lip seal, fill the small cavity between the two lips with grease as well. This both protects the lips during initial installation and break-in, and also acts as another barrier keeping contaminants out. When installing rubber-coated seals, apply lubricant to the outside diameter as well. This will help prevent the seal from rebounding or backing out from its mounting place.

Oil seals close spaces between moving or stationary mechanical components to prevent lubricants like grease and oil from escaping, while also preventing dust, dirt, moisture, and other contaminants from entering the seal. Also known as shaft seals, dirt seals, lip seals, or grease seals, the primary components of any oil seal include an inner metal ring, which provides structural support, and a spring, which provides interference for effective sealing.
: guarantees dynamic and static sealing.
Oil seals, which are also referred to as radial shaft seals, rotary shaft seals, grease seals, or fluid seals, are used to close the gaps between fixed and moving parts of mechanical equipment. They are put between moving and stationary mechanical parts to make sure that moisture, contaminants, corrosive materials, and abrasives don’t cause any damage to these parts.
