GUARDIAN™ bearing isolators offer exceptional bearing protection for pumps, motors, and bearing supported industrial equipment under the harshest conditions.
Garlock is pleased to announce the offering of the GUARDIAN™ bearing isolator in additional sizes of 12 to 24 inches for your larger applications. We call it the GUARDIAN™ XL. We offer 7 day lead times in order to assist you with your needs.
GUARDIAN™ products are composed of a patented Cam-Lock design and patented unitizing ring. This unique design eliminates the metal-to-metal contact between rotor and stator that causes vibration and misalignment which causes traditional O-rings to shred.
FEATURES and BENEFITS

Garlock Patented Cam-Lock Design
The patented Cam-Lock design of the GUARDIAN™ provides excellent bore retention while allowing easy installation by hand, without the need for an arbor press. The interference fit of other designs require special tools for installation and may generate bronze shavings and result in bore scoring.
The patented unitizing element prevents the rotor and stator to contact. The unitizing element also prevents the components from separating during operations which could cause premature failure. The unitizing element is integrated into all KLOZURE metal isolator designs.
