Engineered, precision bearing surfaces extend the calibrated life of the M line to as many as 60,000 cycles or more and ensure the most reliable performance possible. In addition to flawless operation at release, calibration is completely external, unlike traditional mechanisms that require disassembly and the replacement of blocks and shims. Meets or exceeds ANSI/ASME B107.14m, GGG-W-686C, GGG-W-2843 and ISO6789.
