Rotary Seals

High Performance Seals

RB Series :: MC Series :: SB Series

Rotaflon™ RB series

The Rotaflon™ RB high performance rotary shaft seal combines an elastomer seal lip for maximum flexibility to adapt quickly to ever changing operating conditions with a proprietary blend of polymer based material incorporated into the sealing edge of the seal lip to accommodate maximum wear resistance.  Combining these characteristics makes for a more durable seal with a longer operational life and better performance than conventional elastomer lip seals.

 

Some of the advantages of the Rotaflon™-RB series design are:

• High surface speeds up to 6000 ft/min
• Capable of sealing up to 150 PSI. with PV (feet per min. x PSI) values of 100,000
• Can tolerate dry running conditions
• Low friction and wear
• Easy to assemble and disassemble
• Temperature range: -30º to 250ºF
• Maximizes seal life

* Maximum values depend on seal material, seal configuration and working environment. For maximum seal life expectancy, do not operate your seal beyond 50% at the combined limits of the working conditions. Please consult our engineers or call 1-800-283-7140 for advice.
