Product Description

Large internal bores in engines, gearboxes, pumps, compressors, and heavy equipment can develop dimensional variation, taper, or ovality through wear and machining. Accurate inspection at multiple depths helps determine whether a component remains within the required dimensional limits.

The Mitutoyo 568-936 Digital ABS Borematic interchangeable head set provides one measurement system for bore sizes from 2–4" (50.8–101.6 mm). It combines one 568-015 ABSOLUTE display unit with four interchangeable heads covering 2–2.5", 2.5–3", 3–3.5", and 3.5–4".

The three-point self-centering measuring method helps position the head consistently inside the bore. This makes it suitable for checking internal diameters, taper, and ovality at different measurement depths. TiN-coated measuring contact points are designed for repeated inspection and can reach close to the bottom of blind holes.

The gauge provides .00005" (0.001 mm) resolution and uses an electrostatic capacitance ABSOLUTE encoder. The 8.5 mm LCD display rotates through 330° and supports inch/metric measurement. The ABSOLUTE system helps retain the established origin without requiring repeated zero-setting during normal operation.

For tolerance inspection, the display supports user-defined upper and lower GO/NO-GO limits with judgement zoom. Other functions include ZERO/ABS, 2-point preset, data hold, error alarm, low-battery alert, and function lock.

The 568-936 also supports Digimatic SPC data output. Measurement data can be transferred using SPC cables 905338 or 905409, USB Input Tool Direct 06ADV380F, or U-WAVE-T wireless connectivity through the appropriate cable.

The set includes adaptor 216558 and setting rings 177-315 and 177-319. The correct head is fitted to the 568-015 display unit and mastered using the appropriate setting ring before measurement.

For applications where separate complete gauges are preferred for different bore ranges or operators, compare the Mitutoyo 568-968 and 568-969 complete unit sets.

Key Benefits

• 2–4" large bore coverage: Four interchangeable heads cover 2–2.5", 2.5–3", 3–3.5", and 3.5–4" bore ranges.

• One digital display: The 568-015 display unit works with all four heads.

• Three-point self-centering: Helps position the measuring contacts consistently inside large internal bores.

• High-resolution measurement: Provides .00005" (0.001 mm) resolution.

• Taper and ovality inspection: Measure at different depths and positions to identify dimensional variation.

• Blind-hole capability: TiN-coated measuring contacts can reach close to the bottom of suitable blind bores.

• GO/NO-GO judgement: Configure upper and lower tolerance limits for faster inspection decisions.

• SPC connectivity: Transfer measurement results through compatible Digimatic, USB, or U-WAVE-T solutions.

• Inch/metric operation: Switch between inch and metric measurement modes as required.

Who This Product Is Best For

The Mitutoyo 568-936 is suitable for workshops and inspection teams that regularly measure large internal bores between 2" and 4" and want multiple measuring ranges from one display unit.

Typical users include:

• Engine rebuilding workshops

• Heavy-equipment service companies

• Fleet maintenance workshops

• Compressor repair teams

• Pump and gearbox service companies

• Power-generation maintenance teams

• CNC machining and quality-control departments

• Industrial equipment inspection teams

Typical applications include engine cylinder bores, cylinder liners, gearbox and axle housings, compressor bodies, pump casings, large bushings, bearing seats, and other machined internal diameters within the 2–4" range.

How to Use / How It Works

1. Select the correct measuring head.
Choose the head covering the required bore size: 2–2.5", 2.5–3", 3–3.5", or 3.5–4". Attach it to the 568-015 display unit using adaptor 216558.

2. Master the measuring head.
Use the appropriate setting ring supplied with the set. Insert the measuring head into the setting ring and establish the reference using the ZERO/ABS or preset function.

3. Measure the bore.
Operate the snap-open lever, position the head inside the bore, and release it so the three-point contacts self-centre. Take measurements at the top, middle, and bottom when checking for taper.

4. Check dimensional variation.
Take measurements at appropriate positions and depths to identify changes in diameter, taper, or ovality.

5. Evaluate and record the result.
Use the displayed measurement with configured GO/NO-GO limits, data hold, or transfer the result to compatible SPC software.

When changing to another interchangeable head, follow the appropriate mastering procedure before continuing measurement.

Frequently Asked Questions

What is included with the Mitutoyo 568-936?

The set includes one 568-015 display unit, four interchangeable heads covering 2–2.5", 2.5–3", 3–3.5", and 3.5–4", adaptor 216558, and setting rings 177-315 and 177-319.

What bore range does the Mitutoyo 568-936 cover?

The 568-936 covers internal diameters from 2–4" (50.8–101.6 mm) using four interchangeable measuring heads.

What is the resolution?

The gauge provides .00005" (0.001 mm) resolution.

Can the Mitutoyo 568-936 check taper and ovality?

Yes. Taking measurements at different depths and positions can help identify changes in internal diameter, including taper and ovality.

Can it measure blind holes?

Yes. The TiN-coated measuring contacts can reach close to the bottom of suitable blind holes, depending on the bore geometry and depth.

Does the 568-936 support GO/NO-GO inspection?

Yes. The display supports user-set upper and lower tolerance limits and GO/NO-GO judgement with a zoom display.

Can measurement data be transferred to SPC software?

Yes. The gauge supports Digimatic SPC output and can be connected using SPC cables 905338 or 905409. USB Input Tool Direct 06ADV380F and U-WAVE-T wireless connectivity are also available with compatible accessories.

What is the difference between the 568-936 and the 568-968 or 568-969?

The 568-936 is an interchangeable head set using one display unit with four measuring heads covering 2–4". The 568-968 and 568-969 are complete unit sets designed around their respective bore ranges, with separate gauge units for the applicable sizes.

Which interchangeable head set should I choose?

Choose according to your required bore range. The 568-936 covers 2–4". For 1–2" applications, the Mitutoyo 568-930 covers the smaller range with interchangeable heads.
