SRA1-2-3 FABRIC REINFORCED ROTARY SEALS

February 27, 2019

The Fabric Reinforced Rotary Seal is widely used in heavy machinery and engineering industries such as Rolling Mills, Gear Boxes etc.

The material generally used is NBR (Nitrile) for the sealing lip which is bonded on the outer body made out of a hard and rigid fabric reinforced with NBR. This seal also proves most cost effective when compared to other types of seals.

Special features

SRA1 is the basic profile used wherever the adequate lubrication is provided by the hydraulic fluid.

SRA2 has additional slots provided on the back face  of the seal to enable the lubricant to enter through these slots for lubricating the sealing lips.

SRA3 with additional distribution groove on seal body thus eliminates machining groove in housing. These seal is recommended to use back to back.

These seals can be manufactured and supply in with single split (Straight Cut). Split Seals are used to reduce downtime in replacing seals, especially during shut down time, without removing heavy couplings or parts.
