Chesterton’s 19K Bearing Bands are the solution to costly cylinder machining and repairs. They extend cylinder life by preventing direct metal-to-metal contact of moving parts.

Advantages of 19K compared to conventional bearing materials:

• Manufactured from glass fiber reinforced thermoplastic polyamide resin,
  heat stabilized nylon.
• Traps and absorbs metal particles.
• Same load carrying capacity as bronze.
• Less expensive and easier to install than bronze.

19K Bearing Bands are designed specifically for metric sizes.
