Mitutoyo 115-253 Micrometer, Spherical Face, 0-1in, 0.00015in

Description

The Mitutoyo 115-253 is a mechanical, spherical-faced micrometer designed specifically to measure the wall thickness of tubing and other curved surfaces. It features both a spherical anvil and a spherical spindle to ensure accurate, repeatable measurements on contoured workpieces.

Key features

• Dual spherical contact points: The primary feature of this micrometer is its spherical (or ball-shaped) anvil and spindle. This unique design allows for accurate, single-point contact measurement of the wall thickness of tubes, pipes, and bearings, where a flat-faced micrometer would make inconsistent or inaccurate contact.
• Carbide-tipped faces: Both measuring faces are tipped with carbide for superior durability and resistance to wear, ensuring long-term accuracy.
• Ratchet-stop mechanism: This feature applies a constant and uniform measuring force to the workpiece, which helps eliminate over-tightening. This ensures precise and repeatable measurements every time.
• Satin chrome finish: The sleeve and thimble are coated with a satin chrome finish. This makes the markings and graduations easier to read by reducing glare.
• Spindle lock: A locking nut is included to secure the spindle in place once a measurement has been taken. This prevents the reading from being accidentally changed during removal or inspection.
• Protective case: The micrometer comes with a fitted plastic case for safe storage and transport, protecting the instrument from damage.
• Manual (analog) reading: As a mechanical micrometer, it provides readings via a vernier scale on the barrel and thimble.
