Avoid metal contact between stator and rotor, which will cause vibration and deflection, which will cause the traditional O-ring to break

GUARDIAN ™ bearing isolators provide excellent bearing protection for pumps, motors and bearings in rotating equipment in the most demanding conditions. GUARDIAN ™ products feature a patented cam lock design and combination ring. This special design avoids metal contact between the stator and the rotor, which will cause vibration and deflection, which will cause the traditional O-ring to break. Country of Origin: United States

Features / Benefits
  • Easy installation-no special tools required
  • Reduce friction loss
  • Compatible with safety and industrial manufacturing standards

Attachment information
Garlock's patented cam lock design

GUARDIAN®'s patented cam lock design enables excellent drilling retention and easy manual installation without special tools. Other designs of interference fits require special tools for installation and may produce bronze shavings, which can lead to boring.

Combination element

Patented combination element prevents rotor and stator contact. The combination element also prevents the parts from being separated during operation, otherwise it may cause premature failure. All KLOZURE metal isolator designs cover combination components.
