PRODUCT SUMMARY
The Mitutoyo 122-106-10 Series 122 blade micrometer measures narrow grooves, keyways and recessed features from 125–150 mm. It provides 0.01 mm graduation, ±4 µm accuracy and a non-rotating spindle with a 0.75 mm Type A hardened steel blade for controlled metric measurement.
PRODUCT DESCRIPTION
The Mitutoyo 122-106-10 is a Series 122 mechanical blade micrometer designed for measuring groove diameters, keyways and recessed features that can be difficult to access with conventional micrometers. Its 125–150 mm measuring range makes it suitable for larger shafts, bearing journals, gearbox components, compressor shafts and other precision-machined parts.
The Type A measuring design uses a 0.75 mm thick hardened steel blade to reach into narrow grooves and slots. This blade-shaped measuring arrangement is suitable for applications such as keyways, snap-ring grooves, spline roots and O-ring grooves where conventional measuring faces may not provide adequate access.
The micrometer features a non-rotating spindle with a 0.5 mm pitch, allowing the measuring blade to remain aligned with the feature as the spindle advances. This is useful when measuring narrow grooves and recessed surfaces where controlled positioning of the measuring faces is important.
A ratchet stop provides a controlled measuring force of 3–8 N, helping maintain consistent contact pressure during repeated measurements. The 122-106-10 provides 0.01 mm graduation and ±4 µm accuracy. Its specified measuring-face parallelism is (3 + R/100) µm, where R represents the applicable range value.
The satin chrome thimble and sleeve provide an analog mechanical reading surface suitable for workshop and inspection environments. Because the measuring range starts at 125 mm, a setting standard is included for zero-setting and reference checks. The main unit weighs approximately 775 g and is supplied in a fitted protective case.
For a larger measurement range, the Mitutoyo 122-107-10 covers 150–175 mm and uses the same Series 122 blade-micrometer concept.

WHO THIS PRODUCT IS BEST FOR
The Mitutoyo 122-106-10 is suitable for rotating-equipment workshops, gearbox rebuilding facilities, heavy machining operations, industrial maintenance departments and dimensional inspection teams.
It can be used by machinists checking component dimensions during production, quality inspectors verifying first-off parts and maintenance engineers inspecting larger shafts and recessed features before repair or rebuilding.
Typical applications include measuring shaft grooves, keyways, snap-ring grooves, spline roots and O-ring grooves on gearbox shafts, compressor shafts, motor shafts and other components within the 125–150 mm range.
It is particularly suitable for workshops working with metric engineering drawings, where measurements need to be read directly in millimetres without unit conversion.
HOW TO USE / HOW IT WORKS
-
Clean the measuring faces and workpiece to remove dirt, chips or other particles.
-
Check the micrometer against the supplied setting standard and verify the reference condition.
-
Open the micrometer enough to position the blade around the groove, keyway or recessed feature.
-
Position the blade squarely against the feature being measured.
-
Operate the ratchet stop until the measuring faces make controlled contact with the part.
-
Read the sleeve and thimble scale using the 0.01 mm graduation.
-
Record the measurement while maintaining the correct measuring position.
For precision inspection, keep the measuring surfaces and component clean and follow the applicable inspection procedure for the part.
FREQUENTLY ASKED QUESTIONS
What is the Mitutoyo 122-106-10 used for?
The Mitutoyo 122-106-10 is a Series 122 blade micrometer designed for measuring narrow grooves, keyways, snap-ring grooves, spline roots and similar recessed features within the 125–150 mm range.
What is the measuring range?
The measuring range is 125–150 mm.
How accurate is the Mitutoyo 122-106-10?
The specified accuracy is ±4 µm, with 0.01 mm graduation. The specified measuring-face parallelism is (3 + R/100) µm, based on the applicable range value.
What type of blade does it use?
It uses a Type A hardened steel blade with a thickness of 0.75 mm.
Why does this micrometer use a non-rotating spindle?
The non-rotating spindle keeps the blade aligned with the measured feature as it moves. This is useful for narrow grooves and keyways where controlled blade positioning is important.
What measuring force does the ratchet stop provide?
The specified measuring force is 3–8 N through the ratchet stop.
Is a setting standard included?
Yes. A setting standard is supplied because the 122-106-10 has a 125–150 mm measuring range rather than starting at zero.
Is the 122-106-10 a metric micrometer?
Yes. The 122-106-10 is a metric mechanical micrometer with 0.01 mm graduation.
What is the difference between the 122-106-10 and 122-107-10?
The 122-106-10 covers 125–150 mm, while the 122-107-10 covers 150–175 mm. Both belong to the Series 122 blade micrometer range.
What is the difference between Mitutoyo 122-106 and 122-106-10?
Both part numbers are associated with the Series 122 blade micrometer for the 125–150 mm size. The 122-106-10 is the order number used for this product listing. If both numbers appear in your store or catalogue, confirm the applicable current order number before creating duplicate product pages.
