Mitutoyo 568-472 Borematic Bore Gauge 3-3.5" | KSA

 Product Summary

The Mitutoyo 568-472 Borematic bore gauge measures internal diameters from 3.0–3.5" (76.2–88.9 mm) using a self-centring three-point measuring head. With .00005" (0.001 mm) resolution and ±.0003" (±6 µm) accuracy, it supports inspection of engine cylinders, liners, compressor cylinders and other precision bores. GO/NO-GO judgement, data hold and Digimatic SPC output support efficient dimensional inspection.

 Product Description

Cylinder wear is rarely uniform. An engine bore can develop taper along its depth and ovality across different measurement angles, making reliable dimensional inspection important when deciding whether a component should be reused, honed or rebored.

The Mitutoyo 568-472 Digital ABS Borematic bore gauge is designed for 3.0–3.5" (76.2–88.9 mm) internal diameters. Its three-point measuring system automatically self-centres inside the bore, helping provide consistent readings at different depths and positions.

The snap-open lever allows the user to squeeze the lever, insert the measuring head and release it so the measuring contacts centre inside the bore. Taking readings at multiple depths can help identify bore taper, while rotating the gauge and repeating measurements can help identify ovality.

The gauge provides .00005" (0.001 mm) resolution and ±.0003" (±6 µm) accuracy. Its electrostatic capacitance ABSOLUTE encoder is designed to avoid over-speed errors, while the 8.5 mm LCD digits and 330° rotatable display unit make measurements easier to view during inspection.

The Mitutoyo 568-472 supports inch and metric units, zero/ABS operation, two-point preset, data hold, function lock, error alarm and low-battery alert. GO/NO-GO judgement can be configured using upper and lower tolerance limits, with a zoom display for easier pass/fail interpretation.

TiN-coated measuring contacts can reach close to the bottom of blind holes. For data collection, the gauge provides Digimatic SPC output and can be connected using SPC cables 905338 or 905409, USB Input Tool Direct 06ADV380F or U-WAVE-T wireless connectivity through cable 02AZD790F.

The gauge uses one SR44 battery and provides approximately 5,000 hours of battery life. A matching setting ring is sold separately and is used for origin setting. The 568-472 is also available in the Mitutoyo 568-969 complete unit set covering the 3–4" range.

 How to Use / How It Works

1. Establish the origin

Place the gauge in a matching master setting ring with a known certified diameter. Set the gauge origin according to the manufacturer's procedure before measuring the workpiece.

2. Set the measurement parameters

Select inch or millimetre units and configure the required upper and lower tolerance limits if GO/NO-GO judgement is needed.

3. Measure the bore

Squeeze the snap-open lever, insert the measuring head into the bore and release the lever. The three measuring contacts self-centre inside the bore.

4. Check for taper and ovality

Take measurements at the top, middle and bottom of the bore to identify dimensional changes along its depth. Rotate the gauge and repeat the measurement at different angular positions to assess ovality.

5. Record the results

Use the data-hold function when required, or transfer the measurement through the Digimatic SPC output to compatible data-collection equipment.

Frequently Asked Questions

What range does the Mitutoyo 568-472 measure?

The 568-472 measures internal diameters from 3.0–3.5" (76.2–88.9 mm).

Can the 568-472 check cylinder taper?

Yes. Taking measurements at different depths allows dimensional differences along the bore to be compared and can help identify taper.

Can it check bore ovality?

Yes. Take measurements at different angular positions within the bore and compare the readings to assess variation in diameter.

What is the accuracy of the Mitutoyo 568-472?

The specified accuracy is ±.0003" (±6 µm), with .00005" (0.001 mm) resolution.

Is the setting ring included?

The matching setting ring is sold separately from the individual gauge and is used for origin setting.

Does the 568-472 support inch and metric measurements?

Yes. The gauge can switch between inch and millimetre measurement units.

Does the gauge have GO/NO-GO judgement?

Yes. Upper and lower tolerance limits can be configured for GO/NO-GO judgement, with a zoom display to make the result easier to read.

Can the measurement data be transferred to a computer?

Yes. Digimatic SPC output supports electronic data collection. Compatible options include SPC cables 905338 and 905409, USB Input Tool Direct 06ADV380F and U-WAVE-T wireless connectivity through the appropriate cable.

What is the difference between the Mitutoyo 568-471 and 568-472?
