Mitutoyo 568-473 Borematic Bore Gauge 3.5-4" | KSA

 Product Summary

The Mitutoyo 568-473 Borematic bore gauge measures internal diameters from 3.5–4.0" (88.9–101.6 mm) using a self-centring three-point measuring head. It provides .00005" (0.001 mm) resolution, ±.0003" (±6 µm) accuracy, inch/metric switching, GO/NO-GO judgement and Digimatic SPC output. The snap-open design supports quick inspection of gearbox housings, pump casings and other large bores.

Product Description

Large machined housings can be difficult to move to a dedicated measuring system, especially during maintenance and repair work. The Mitutoyo 568-473 Borematic bore gauge provides a direct way to inspect 3.5–4.0" (88.9–101.6 mm) internal diameters at the component.

The three-point measuring system automatically self-centres inside the bore, helping reduce positioning variation during measurement. Its snap-open lever allows the user to squeeze the lever, insert the measuring head and release it so the contacts centre inside the bore.

The 568-473 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 LCD provides 8.5 mm digits and a 330° rotatable display unit for easier viewing in different inspection positions.

The gauge 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 tolerance checking.

TiN-coated measuring contacts can reach close to the bottom of blind holes. The gauge uses one SR44 battery with an approximate operating life of 5,000 hours.

For electronic inspection records, the Mitutoyo 568-473 provides Digimatic SPC output. Compatible connectivity includes SPC cables 905338 and 905409, USB Input Tool Direct 06ADV380F and U-WAVE-T wireless connectivity through cable 02AZD790F.

A matching setting ring is sold separately for origin setting. The 568-473 is also available as part of the Mitutoyo 568-969 complete unit set covering the 3–4" range.

For applications requiring additional measuring reach, the optional 150 mm extension rod, part number 952623, can be used where compatible with the measurement setup.

 Who This Product Is Best For

The Mitutoyo 568-473 is suitable for workshops and inspection teams measuring large internal diameters from 3.5–4.0".

Typical users and applications include:

• Gearbox and transmission repair workshops

• Pump repair and maintenance teams

• Heavy-equipment service companies

• Oil and gas equipment maintenance teams

• Power-generation maintenance departments

• Compressor service workshops

• Industrial machinery repair teams

• Dimensional inspection departments

Typical applications include gearbox housings, axle housings, pump casings, compressor bodies, large bearing bores, bushings and other machined internal diameters within the 3.5–4.0" range.

 How to Use / How It Works

1. Establish the origin

Use a matching setting ring with a known certified diameter to establish the gauge origin. Follow the manufacturer's setting procedure before measuring the workpiece.

2. Select units and tolerance

Choose inch or millimetre measurement units. If required, configure the upper and lower tolerance limits for GO/NO-GO judgement.

3. Insert the gauge

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

4. Check the bore

Take measurements at the required depth. For a more complete inspection, compare readings at different depths and angular positions to identify dimensional variation.

5. Record the result

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