Split GUARDIAN® Bearing Isolators

The first fully unitized bronze split bearing isolator

M Barnwell Services provides the full range of Garlock’s KLOZURE® Split GUARDIAN® Bearing Isolators in addition to the standard GUARDIAN™ Bearing Isolators. The Split GUARDIAN® Bearing Isolator is the first truly unitized split isolator. It provides bearing protection for motors, pumps, and other machinery in the most demanding environments. If uptime and MTTR (mean time to repair) are your main issues, then Split GUARDIAN® is your best and only choice. Due to its unique split design, the Split GUARDIAN­® can save you thousands of pounds in rigging and maintenance. The average installation takes minutes rather than hours, and doesn’t require any costly dismantling of equipment or machinery.

Split GUARDIAN® Isolators

Features and benefits of Split GUARDIAN® Bearing Isolators:

  • The split design offers the FASTEST mean time to repair (MTTR) during maintenance
  • Non-contact engineered labyrinth design reduces shaft drag, using 97-99% less energy compared to contact lip seal
  • Unitizing ring prevents seal components from metal-to-metal contact
  • Mean time between failure (MTBF) increased by lifetime bearing protection
  • Excludes contamination and retains bearing lubrication to IP 65 level
  • Consistent sealing efficiency over the lifetime of a bearing
  • Stationary O Ring contact between the seals and shaft prevents shaft grooving damage  and housing damage
  • Patented Cam-Lock O Ring system offers reduced installation time
