Chesterton’s 30K seals are high performance shaft mounted lip seals that provide excellent service in bearing and gearbox applications.

The 30K is available in three distinct PTFE materials developed specifically for sealing applications. The PTFE compounds coupled with the seal design provide excellent fluid compatibility and outstanding performance.

• Each seal is individually machined.
• Dynamic sealing lip is mechanically formed to provide optimal sealing force.
• Static o-ring seal prevents rotation and allows for easy installation and removal.
• Outperforms conventional oil lip seals.
• Does not fret or damage hardened shafts.
• Custom fabricated to meet equipment dimensions.
• Material is selected easily based on system fluid.

Other designs/profiles include:

• 30K, 30KW, 30KSW - shaft mounted lip seals
