Mitutoyo 12AAA218 Cylinder Nosepiece SJ-301/R

Product Description

The MITUTOYO 12AAA218 is a cylinder nosepiece accessory designed for use with the SJ-301/R Surftest portable surface roughness tester. This nosepiece mounts to the instrument to provide a cylindrical reference surface, allowing the gage to perform accurate roughness measurements on contoured or cylindrical workpieces. It measures 30.00 millimeters in overall diameter and ships as a single-unit package. Metrologists, quality control technicians, and machining professionals install this accessory when surface profile measurements require a stable, curved contact reference. The part weighs 1 pound and is manufactured to MITUTOYO's dimensional standards for Surftest instrument accessories.

This cylinder nosepiece is suited for production floor and metrology lab environments where cylindrical or curved surfaces require roughness evaluation. The SJ-301/R is a portable surface roughness tester commonly used in manufacturing and inspection settings. When standard flat-surface measurement is not practical due to workpiece geometry, this nosepiece provides the appropriate interface between the instrument and the part being tested. It is a direct OEM accessory for the SJ-301/R and is installed without modification to the base unit.

Installation Notes

Installation of this nosepiece should be performed by a qualified metrology or quality control technician familiar with Surftest instrument accessories. Power down or disconnect the instrument from any active data connections before attaching or removing nosepieces. Handle the nosepiece carefully to avoid contact with the stylus or measurement surfaces, as contamination or impact can affect measurement accuracy. Refer to the SJ-301/R instrument manual for specific attachment procedures and torque requirements if specified by the manufacturer.
