Fabric Reinforced Rubber Seal R37Rubber Seals

Description

he 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.

Application   

Rotary seals   

Mills   

Civil engineering   

Forging   

Heavy-duty cylinders   

General machinery   

Steel production   

Ship building   

Wind turbines   

Bearings

Materials

Rubber seal: NBR+Fabric (under 100 degree)                    

                       FKM+Fabric (under 180 degree)
Advantages:

Sealing ring is used, in case of adequate lubrication by the medium to be sealed, preferably where shafts pass through walls in mills and large gearboxes in heavy machinery manufacture.

Particularly robust static part

Lasting radial contact pressure

Highly wear-resistant
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.
