Dial indicator shaft alignment

What is digital dial indicator? There are two commonly use methods to align rotating machine shafts using dial indicators. When using a rim-face metho one measurement is taken on the rim of the coupling to determine shaft offset.


Another measurement is taken on the face of the coupling to determine shaft angularity. The primary parts of a dial indicator are the face or dial , the case, and the plunger.

Reliability Direct, Inc. Stan shows you how to perform an alignment in just one or two moves using dial indicators and the Verti-Zontal Compound. This is best accomplished with a dial indicator using the process desc. Check Out Top Brands On eBay.


The fixtures can easily be reconfigured to perform the Rim and Face alignment method if necessary. In the right hands, a very accurate alignment can be performed with dial indicators. The easy-to-read dials offer more precise measurement than stylus indicators.

Objective: Detect shaft and coupling runout conditions. Activity: Use magnetic base with dial indicator. Straight Edge Techniques. This video gives a brief overview of how dials can be used to measure shaft alignment , and can even be adjusted to show the true. Re-measure and record final alignment values.


Mounting the dial indicator fixtures To mount the fixtures follow these steps: 1. With the coupling broken, mount the fixture to the stationary shaft or coupling hub. Span the coupling with a rod. Rotate the fixture to 12:00.


Attach the face dial indicator. This system is capable of addressing radial and angular misalignment problems and can be set up within minutes. It is true that flexible couplings are designed to take misalignment, typically up to 4mils or more radial offset of the shafts. However, even under the best of circumstances, it will be a time-consuming task with many traps and pitfalls for the unwary or the untrained.


Using dial indicators properly for shaft alignment is almost an art form. One key consideration is the measurement setup. Skip to main search Amazon Prime.

This past week I had the pleasure of teaching a couple hybrid shaft alignment training classes–part of each class was using the rim and face dial indicator method and the other part was using a laser alignment tool. For most alignment applications the smaller sized indicators should be used to reduce indicator bar sag.


The set comes in a fitted case for organization and protection. However, several precision tools are commonly used in alignment work. Each one has a part to play in doing alignments. Defining Shaft Misalignment III.
