THE TRUNCATED CYLINDER IS THE LEAST EXPENSIVE MODIFIED CYLINDER. IT IS USED IN CLOSE QUARTERS WHERE REDUCED PROFILE HEIGHT AND OR INCREASED STABILITY DUE TO THE FLAT BASE ARE IMPORTANT.

THESE HARDENED AND DIMENSIONALLY STABILIZED STAINLESS STEEL CYLINDERS ARE PRECISION GROUND AND MACHINE LAPPED TO PROVIDE EXCELLENT CYLINDRICITY WITH CLOSE DIMENSIONAL TOLERANCE.

THE HIGHLY UNIFORM LOW MICROINCH SURFACE TEXTURE GENERATED BY THE MACHINE LAPPING LEADS TO LOW HYSTERESIS AND EXCELLENT REPEATABILITY.

TWO PARALLEL MOUNTED CYLINDERS FORM A VERY HIGH QUALITY SUBSTITUTE FOR THE HARD-TO-MANUFACTURE VEE GROOVE. THE TRUNCATED CYLINDERS ARE USUALLY CLAMPED OR GLUED INTO POSITION.
