Shaft Alignment Tool for In-Line Drive Systems
Keeping your rotating equipment in line - can add years to
your equipment's life span. When misaligned machinery is allowed
to operate uncorrected, the resulting vibration will eventually
cause bearing, shaft, seal and coupling failures. Your company
loses two ways: first in the outlay of funds to repair or replace
the machinery, and, more importantly, you lose productivity
and income every hour the machine is down.
Peterson Alignment tools utilize the Rim and Face Method
of Shaft Alignment, far and away the most common method - more
accurate than straight edge or magnetic base systems and much
less expensive than laser alignment tools.

30RA
Our #30RA alignment system was designed to handle larger equipment
- shaft sizes up to 8" in diameter are no problem - but
versatility demanded that it also handle smaller shaft sizes
like the #20RA. What you get is an alignment system that can
handle virtually any alignment job you can throw at it.
#30RA Kit Contents (link to 62k picture of #30 RA)
- Two (2) alignment frames, each with three (3) - 1/2 inch diameter mounting hole for tubing.

- 2 dial indicator assemblies with swivel joints and mounting rods.
- 1/2" diameter tubing: 2 x 5", 7", 9", 12" and 2 x 15" lengths.
- #555 Inspection mirror by General.
- Allen key, 3/16".
- Instruction manual.
- FastMath(tm) worksheets.
- Durable carrying case with handle.
