Measurement Tip Mahr 4304320 for 802EW/NW, ball Ø4.00 mm, length 31 mm

Replacement measurement tip by Mahr with a spherical probe head of 4.00 mm diameter and a total length of 31 mm, designed for compatibility with 802EW and 802NW measuring instruments. The tip restores or customizes contact probing capability for bore, gauge and small-feature inspection tasks where a compact, accurate ball stylus is required. Constructed to meet the dimensional requirements for precise contact measurement and to fit standard compatible probe holders.

Advantages

This measurement tip provides a defined, wear-resistant ball contact geometry that supports repeatable contact points and consistent measurement results. Its compact 31 mm length makes it suitable for confined spaces while maintaining probe stability. Designed for direct replacement on compatible Mahr probes, the tip simplifies restoration of measurement setups and reduces downtime when worn or damaged tips need to be exchanged.

Suitable for

• Bore and internal diameter inspection
• Gauge and fixture verification
• Contact probing of small features and edges
• Replacement of worn or damaged probe tips on compatible instruments

Key specifications

• Ball diameter: 4.00 mm
• Total length: 31 mm
• Probe shape: spherical (ball) tip
• Compatibility: designed for use with compatible 802EW and 802NW probe models
• Application: precision contact measurement for bores, gauges and small features

How to use

Mount the measurement tip securely into the appropriate compatible probe holder following the instrument manufacturer's instructions for attachment and torque settings. Verify alignment and seating of the ball tip before performing measurements. Use gentle contact and appropriate probe approach angles to avoid side loading; perform a calibration or reference measurement on a known standard after installation to confirm correct measurement behavior.

Usage recommendations

For best results, inspect the ball surface regularly for wear or contamination and clean with a lint-free cloth and suitable solvent if necessary. Avoid impacts or lateral forces on the ball tip during handling and measurement. When replacing tips, follow the measuring instrument's service guidelines to ensure secure mounting and reliable measurement accuracy.
