Mitutoyo 155-126 Telescoping Gage 3.5 to 6 Inch

Product Description

The MITUTOYO 155-126 is a telescoping gage designed for measuring inside diameters, bores, and slots with a measurement range of 3.5 to 6 inches. The telescoping spindle locks at the measured dimension, allowing the gage to be withdrawn and read with an outside micrometer or caliper. With an overall length of 5.9055 inches, the 155-126 provides the reach needed for typical bore and housing measurements encountered in mechanical and HVAC equipment service. The satin chrome finish reduces glare and resists corrosion during regular shop use. Machinists, millwrights, and service technicians rely on telescoping gages like this one for quick, accurate inside-dimension transfer measurements.

The MITUTOYO 155-126 is suited for inspecting bores, cylinders, housings, and valve bodies in light industrial and trade service environments. It is commonly used in mechanical shops, HVAC equipment overhaul, pump service, and general maintenance work where inside measurements in the 3.5 to 6 inch range are needed. The 5.9055 inch overall length makes it practical for shallow to moderate-depth bore checks without requiring additional extensions.

Key Features

• Measurement range of 3.5 to 6 inches covers a wide span of bore and housing sizes
• Overall length of 5.9055 inches provides adequate reach for most standard bore depths
• Locking spindle holds the measured dimension for transfer to an outside micrometer or caliper
• Satin chrome finish reduces light glare and provides corrosion resistance in shop environments
• Compact and lightweight at 0.1 pounds for easy one-hand use

Compatibility

Designed as an OEM-style telescoping gage for general inside-dimension measurement applications requiring a range of 3.5 to 6 inches.

Installation Notes

Telescoping gages are used by machinists, millwrights, and service technicians as a transfer measuring tool and require no installation. Compress the spindle, insert into the bore, release and allow it to expand to the bore wall, then lock and withdraw for measurement with a calibrated outside micrometer. Handle with care to avoid dropping or impacting the gage, which can affect measurement accuracy. Store in the provided case when not in use to protect the contact surfaces.
