Product Description
Oil seal is also known as shaft seal. They are often called grease, fluid or dirt seals. Oil seal is an integral part in any rotating and moving part assembly. They close spaces between stationary and moving components in mechanical equipment. In most applications, the seal is either partially or temporarily immersed or is simply exposed to splashing lubricant, particularly in engines, transmissions, gearboxes or axles. They are vital components of almost every type of machine and vehicle in operation. An oil seal normally consists of three basic components: The Sealing Element (the nitrile rubber part), the Metal Case, and the Spring. It is a widely used sealing component. The function of a seal is to prevent the leakage of medium along the moving parts. This is mainly achieved by the sealing element. 

Oil Seal Cross Reference

SC-Type
The SC profile rotary shaft seal is the rubber covered metal shell oil seal a single metal cage with a rubber coating and a primary sealing lip with integrated spring. The metal shell performs as a support. The spring provides the seal lip with radial pressure to avoid lubricant leakage. Two different O.D designare available : Flat rubber sheath as well as wavy.This type is not recommended for use in heavy polluted environments.

Installation Instructions

To provide effective sealing, radial shaft seals must be installed properly. An experienced installer with suitable tools, working in a clean environment, is recommended to provide proper installation. To facilitate seal installation and to achieve initial lubrication, prior to installation, NextGen Tech recommends wiping the shaft and seal with the lubricant that is going to be retained. While the outside diameter of metal-cased seals can be lightly lubricated to ease installation, the outside diameter of rubber covered seals should always be lubricated.
Seals with an auxiliary, contacting lip can also be filled with grease between the sealing lip and auxiliary lip to reduce frictional moment. This does not apply to silicone rubber seals and seals with hydrodynamic features.
