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

R37-Type
The Style R37 shaft sealing rings are used when additional lubrication is necessary from the outside. These sealing rings are usually fitted in pairs back-to-back, and this combination effectively seals the bearing lubricant and prevents the penetration of dust and splash water. The sealing rings have a peripheral groove on the outer periphery in addition to the radial grooves. With a fabric reinforced static part that is securely joined to the elastomer sealing lip. The sealing lip is also preloaded with a garter spring.

Fitting & installation

For fabric reinforced seal R37 an axially accessible housing is necessary, as the rings must have low inclination. The Radiamatic 37 rings are supplied with oversize seal width. For reliable function the Radiamatic R rings must be axially compressed to the dimension "L". 
An open housing with cover plate and tightening screws is necessary. Specific deformation forces are necessary for the compression. The cover plate and the tightening screws are to be designed appropriately. Please request recommended values.

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.
