Crafted from high-quality oil-resistant materials, the 30x42x7 oil seal is impervious to the corrosive effects of petroleum products. The integrity of the seal is paramount; any compromise could lead to leaks that jeopardize the machine's lubrication and, consequently, its operational efficiency. Such a seal must maintain its flexibility and resilience under diverse conditions, from extreme temperatures to high-pressure environments, all while enduring the constant motion of rotating shafts.
When the oil seal material and the chemical are not compatible, there will be a chemical attack, which increases at high temperatures. The only way to remedy this is to select the right material for your application. If you’ll be dealing with harsh chemicals, choose oil seals that are made with reliable materials for their compatibility.
A PU oil seal is essentially a barrier that seals off mechanical parts, particularly those in contact with oils or other lubricants. The 'PU' in the term refers to polyurethane, a versatile material known for its high resilience, excellent abrasion resistance, and ability to withstand extreme temperatures. This makes it ideal for use in harsh operating conditions where conventional rubber seals may fail. The process of replacing the gasket requires precision and expertise. It involves removing the valve cover, cleaning the mating surfaces, and then installing a new gasket. It's a task best left to professional mechanics, as even a small error can lead to recurring leaks or other complications.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.
Air side face The oil seal surface vertical to the center line of the shaft on the side that does not come in contact with substances to be sealed is called the back face.
4. SHAFT SPEED: As different shafts move at different speeds you need to consider the runout, the housing bore, and oil type being sealed. Ensure you select a seal that will not suffer from abrasions or spiralling.
