Mitutoyo 155-124 Telescoping Gage 1.25-2.125 Inch Range

The Mitutoyo 155-124 is a precision telescoping gage designed for accurate internal measurement of bores, holes, and groove widths in the 1.25 to 2.125 inch range. This essential measurement tool features a spring-loaded plunger mechanism that expands within the bore, allowing technicians and machinists to determine internal diameters with precision and reliability.

Key Features:

• Measurement range: 1.25 to 2.125 inches
• Spring-loaded plunger expands automatically within bores and grooves for accurate measurement transfer
• Knurled clamp provides secure locking of the contact points once proper measurement is achieved
• Hardened and ground contact points ensure long-term accuracy and durability
• Can be used to measure internal diameters, groove widths, and recessed dimensions
• Available individually or as part of complete set (Part Number 155-903)

Mitutoyo telescoping gages are trusted by professionals in manufacturing, automotive, aerospace, and precision machining environments. To use, compress the plunger, insert into the bore, release to allow spring expansion, rock gently to find the maximum diameter, lock the clamp, and measure the expanded dimension with an external micrometer or caliper.
