85*145*12/37 Shaft Differential Oil Seal 0219975947

The function of the oil seal is to isolate the parts that need lubrication from the output parts in the transmission parts, so as not to let the lubricating oil leak. It is usually used in the transmission parts.The oil seal is composed of metal, rubber and spring.
The skeleton acts as a reinforcing steel bar in concrete members and keeps the shape and tension of the oil seal.
The NBR skeleton oil seal is made of high-quality nitrile rubber and steel plate, with stable quality and long service life.
It is widely used in automobile, motorcycle crankshaft, camshaft, differential, shock absorber, engine, axle, front and rear wheels, and other parts.

The rear differential delivers engine power to the wheels and allows them to rotate at varied rates, particularly during turns. A hypoid gear set consisting of a ring gear and a pinion gear is used by the differential to shift the direction of engine torque so that the vehicle’s drive wheels turn as they should.

In order for your car's differential to work, its gears and bearings should be properly lubricated with differential fluid. Your rear differential seal is a type of seal in your differential that prevents the fluid from leaking out.

How long do differential seals last?

There's no set interval for replacing a differential pinion seal, as it can vary depending on driving conditions, mileage, and other factors. However, most mechanics recommend inspecting your differential seals for signs of wear and tear every 50,000 to 100,000 kilometers, and replacing them as needed.

Truck Oil Seals are a very important component of a truck’s engine system. They are designed to keep lubricating oil in and contaminants out of the system. Oil seals help reduce friction between rotating components and prevent oil leakage.

Truck oil seals are made up of a rubber seal and a metal housing. The rubber seal is normally made of a synthetic rubber such as nitrile butadiene rubber or polychloroprene which is a blend of these two rubbers. This rubber is designed to withstand high temperatures, pressure and oil viscosity. The metal housing is generally made of stainless steel or aluminum and is designed to provide the oil seal with adequate support and protection against the environment. The joint between the rubber seal and metal part can be filled with a sealing compound such as silicone or polyurethane. The combination of all these materials provides the oil seal with a good seal and long service life.

The primary function of a truck oil seal is to ensure the engine has sufficient lubrication. Without the oil seal, friction between contact surfaces could cause excessive heat buildup and damage to surfaces. The oil seal also helps reduce oil leakage which in turn helps protect other engine components from contamination and excessive wear.

There are many types of oil seals on trucks, and there are four categories according to the installation location: truck engine oil seals, truck gearbox oil seals, truck axle oil seals, and truck wheel hub oil seals.Professional truck oil seal manufacturer, various types of accessories, if you have any, please contact us.
