Chesterton 33K Split Rotary Seal
Split Design Avoids Costly Equipment Disassembly

  

​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​Chesterton's patent-pending 33K Split Rotary Seal can be used in many non-pressure applications, including bearing protection for pumps, gearboxes and rollers. The innovative split design eliminates the need and associated costs for equipment disassembly while improving seal performance of conventional lip seals. Installation time can be reduced from hours to minutes because the split assembly is unitized.

  • Fast: The patent pending split design eliminates the need for equipment disassembly.
  • Easy: No need for​ equipment modification since all seals are made to order.
  • Reliable: High-performance materials are proven to outperform conventional lip seals
