Vibration meter
The Model 200 heavy-duty vibration meter troubleshoots rotating machinery for velocity vibration measurements and cross-checks readings to diagnose the health of motors, pumps, and fans.
FEATURES & BENEFITS
- Measures displacement and acceleration for trending and analysis
- Digital LCD display and push-button operation
- Operates on 9-V alkaline battery
- Audio output jack for headphones determines source of vibration

Ball bearings
Explorer deep groove ball bearings achieve smooth and quiet operation, high running accuracy, increased speed capability, lower friction and operating temperatures, and longer service life.
FEATURES & BENEFITS
- Optimized raceways and cage geometry for running accuracy to ISO tolerance class P5 and ABMA ABEC Class 5 (to 52-mm O.D.)
- Available in many bore sizes and dimensions
- Dimensional accuracy to ISO Class 6 and ABMA ABEC Class 3
- Width tolerance tighter than ISO tolerance Class Normal for lower stackup in shaft system
