Measuring Roller INSIZE 4110-3D80 — precision gauge roller Ø3.80 mm, resolution 0.001 mm

INSIZE 4110-3D80 is a precision measuring roller with a nominal diameter of 3.80 mm and a resolution of 0.001 mm. It is designed for contact measurement and for transferring small linear movements to indicators or measurement systems. The roller is compatible with dial indicators, test stands and measurement fixtures used in machining and quality control environments where fine incremental readings are required.

Advantages

The precision gauge roller provides high resolution and repeatability for contact measurements, enabling accurate transfer of linear displacement to measuring instruments. Its small nominal diameter of 3.80 mm allows measurement of narrow features and small radii where larger rollers would not fit. The construction is intended to integrate with standard indicator mounts and test stands, offering straightforward installation and reliable mechanical contact for incremental measurement tasks.

Suitable for

• Transferring linear motion to dial indicators and digital comparators
• Measurement fixtures and test stands in quality control
• Machining inspection of small diameters, grooves, and profiles
• Precision incremental measurement where 0.001 mm resolution is needed

When it may not be suitable

This measuring roller is intended for contact measurement and small displacement transfer; it is not suitable for non-contact or high-speed dynamic measurement where inertial effects or surface damage could affect readings. It also may not be appropriate for applications requiring larger contact diameter or for heavily profiled/rough surfaces that can cause excessive wear or inconsistent contact.

Key specifications

• Nominal roller diameter: 3.80 mm
• Measurement resolution: 0.001 mm
• Function: contact measuring roller for linear displacement transfer
• Typical compatibility: dial indicators, test stands and measurement fixtures
• Primary use areas: machining, inspection and quality control

How to use

Mount the INSIZE measuring roller in the holder or spindle of the dial indicator or test stand following the instrument manufacturer’s mounting instructions. Ensure the roller contacts the measured surface with gentle, consistent pressure and that the contact line is perpendicular to the direction of the linear movement being measured. Rotate the part or move the roller along the surface so the roller rolls smoothly, transferring the displacement to the indicator. Avoid side loads and excessive force that could impair accuracy or damage the roller surface.

What to consider before purchase

• Confirm compatibility with your dial indicator, comparator or test stand mounting system
• Verify that a 3.80 mm contact diameter and 0.001 mm resolution meet your measurement requirements
• Consider surface finish and part geometry to ensure reliable rolling contact
• Assess expected measurement frequency and environment for wear considerations

Usage recommendations

For best results, use the roller on smooth, clean surfaces and check seating and alignment before each measurement session. Regularly inspect the roller for wear or contamination and replace if surface degradation affects repeatability. Pair the roller with a calibrated indicator and stable mounting to maintain the specified 0.001 mm resolution in routine inspection tasks.
