Spi 14-041-8 Gear Tooth Gage 6 to 80mm 14 Leaf

Product Description

The SPI 14-041-8 is a 14-leaf gear tooth gage used to measure and verify gear tooth pitch across a range of 6 to 80mm. Each leaf is 2 inches in length and stamped from stainless steel for durability and corrosion resistance. The gage folds compactly like a feeler gage set, allowing technicians to fan out individual leaves and match them directly against gear teeth to confirm pitch and pressure angle. With a pressure angle of 14.5 degrees, this tool is suited for inspecting standard involute gears in mechanical, industrial, and maintenance applications. Machinists, millwrights, and maintenance technicians use this gage during gear inspection, replacement verification, and equipment overhaul.

The 14-041-8 is designed for use in shops, manufacturing facilities, and field maintenance environments where gear identification or verification is required. It covers a wide pitch range in a single compact tool, making it practical for technicians who service a variety of gear-driven equipment including gearboxes, conveyors, and industrial machinery. The stainless steel construction holds up to repeated use in oily or humid shop conditions without degrading measurement accuracy.

Key Features

• 14 individual leaves covering a pitch range of 6 to 80mm
• Pressure angle of 14.5 degrees for standard involute gear inspection
• Leaf length of 2 inches for direct tooth-profile matching
• Stainless steel construction resists corrosion and wear
• Compact folding design for easy storage and portability

Compatibility

Designed for inspecting and identifying standard involute gears with a pitch range of 6 to 80mm and a 14.5-degree pressure angle across a wide range of gear-driven industrial equipment.

Installation Notes

This is a hand measurement tool and does not require installation. Machinists and maintenance technicians should clean gear teeth of grease and debris before attempting to match leaves for accurate pitch identification. Store the gage folded and protected from impact to preserve leaf geometry and measurement accuracy.
