Product Summary
The Mitutoyo 568-466 Borematic bore gauge 0.8-1 inch measures internal bores from 20.32 to 25.4 mm, making it suitable for bearing seats, pump housings, hydraulic ports, and other precision bores. Its self-centering three-point measuring head provides repeatable diameter readings, while ±.0003" (±6 µm) accuracy and .00005" (0.001 mm) resolution support close-tolerance inspection. GO/NO-GO judgement and SPC output help streamline quality checks. Contact General Tech at +966 569 289 544 for pricing and availability in Saudi Arabia.
Product Description
A bearing seat needs to match the required fit closely. An oversized bore can allow an outer bearing ring to move in the housing, while an undersized bore can affect the intended fit. Checking the seat before assembly helps identify dimensional issues before the bearing is installed.
The Mitutoyo 568-466 Borematic bore gauge is designed for internal diameter inspection across a .8–1.0" (20.32–25.4 mm) range. It uses a three-point self-centering measuring head to position the contact points around the bore and provide a direct internal diameter reading.
The snap-open lever supports quick operation: squeeze the lever, insert the measuring head into the bore, release it, and allow the contacts to self-centre. This makes the gauge suitable for repeated inspection of bearing seats, pump housings, hydraulic ports, gearbox covers, and other machined components.
The 568-466 provides ±.0003" (±6 µm) accuracy with .00005" (0.001 mm) resolution. Its LCD uses 8.5 mm digits and the display unit can rotate through 330°, allowing the reading to be positioned toward the operator.
The electrostatic capacitance ABSOLUTE encoder maintains the measurement origin throughout the battery life and supports unlimited response without over-speed errors. TiN-coated measuring contact points can reach close to the bottom of suitable blind holes and recessed seats.
For longer or deeper housings, the optional 150 mm extension rod 952622 can provide additional reach where applicable. A matching setting ring is sold separately and is used to establish the measurement reference before inspection.
The gauge also supports GO/NO-GO judgement using user-defined upper and lower limits. This allows operators to quickly evaluate whether a bearing seat or other bore is within the specified tolerance.
For quality documentation, measurement values can be held or transferred through Digimatic SPC output. Compatible options include SPC cables 905338 (1 m) and 905409 (2 m), USB Input Tool Direct 06ADV380F, and U-WAVE-T wireless connectivity through the applicable connecting cable.
The Mitutoyo 568-466 is the next size above the 568-465, which covers .650–.800", while the 568-467 covers 1.0–1.2". The 568-966 set can be considered where multiple Borematic sizes are required.

How to Use / How It Works
-
Prepare the reference: Use a suitable setting ring covering the .8–1.0" range. The setting ring is sold separately.
-
Set the origin: Insert the gauge into the setting ring, press ORIGIN, and enter the certified ring dimension according to the instrument procedure.
-
Set tolerance limits: Enter the required upper and lower limits when using GO/NO-GO judgement.
-
Insert the gauge: Squeeze the snap-open lever and insert the measuring head into the bearing seat or bore.
-
Release and centre: Release the lever and allow the three-point contact system to self-centre inside the bore.
-
Read the diameter: Position the 330° rotatable display for convenient viewing and record the measurement.
-
Transfer the result: Hold the reading or send it to a compatible SPC system through the appropriate cable, USB Input Tool Direct, or U-WAVE-T connection.
Frequently Asked Questions
What range does the Mitutoyo 568-466 measure?
The 568-466 measures .8–1.0" (20.32–25.4 mm) internal diameters and supports inch or millimetre measurement.
How accurate is the Mitutoyo 568-466?
The specified accuracy is ±.0003" (±6 µm) with .00005" (0.001 mm) resolution.
