What is a caliper?
A caliper is a specialized tool that combines the functionality of a caliper and a caliper. It is designed to measure:
- the thickness of the tooth of the gear wheel at the design depth;
- tooth height.
The design of the device includes two rods converging at right angles:
- the horizontal scale is used to determine the thickness of the gear teeth;
- The vertical scale allows you to set the height from the top of the tooth at which the measurement is performed.
Tooth thickness is calculated using a horizontal ruler and vernier, and height is calculated using a vertical ruler. The device is installed with an emphasis on the tooth being measured, and the sponges are brought close to the tooth profile.
Where is it applied?
Calipers are widely used in enterprises when:
- manufacture and repair of gear mechanisms (gearboxes, mechanical variators, etc.);
- checking the compliance of the teeth with the standards and requirements for the manufacture of parts;
- gear wear monitoring.
The tool is indispensable in automotive, industrial and other industries where gears play a key role. The rod gauges allow you to work with wheels with a module of up to 26.

Types of Micron rod gauges
There are two main types of devices:
Simple (SZ) is a common variant consisting of:
- measuring head;
- scales (metal rulers with vernier divisions);
- the clamping mechanism for fixing the object.
Digital is a more advanced model with a number of advantages:
- digital display for accurate data reading;
- automatic reset function;
- the ability to save measurement results.
How to choose a caliper?
When buying a Micron caliper, you should pay attention to the following parameters:
- device type (simple or digital) - the choice depends on the required accuracy and budget;
- measurement accuracy is a critical parameter for ensuring product quality;
- quality of materials - reliable components guarantee a long service life and stable readings;
- compliance with the technical documentation - SHZN type rod cutters must meet the manufacturer's requirements and industry standards;
- Units of measurement - models are available with markings in millimeters, inches, and other metric units.
Each Micron caliper is supplied in a hard plastic or wooden case and is accompanied by a product certificate. The document contains all the characteristics and operating standards - this simplifies the accounting and maintenance of the tool at the enterprise.
The use of a rod gauge makes it possible to achieve high measurement accuracy, which directly affects the reliability and durability of gear mechanisms. The correct choice and operation of this device is the key to high-quality production and repair of gears.
