	 Maximum Loading Capacity On Micrometer Heads

The maximum loading capacity of a micrometer head depends mainly on the method of mounting and whether the loading is static or dynamic (used as a stop, for
example). Therefore the maximum loading capacity of each model cannot be definitively specified. The loading limits recommended by Mitutoyo (at less than 100,000
revolutions if used for measuring within the guaranteed accuracy range) and the results of static load tests using a small micrometer head are given below.

1. Recommended maximum loading limit

                         Standard type  (spindle pitch: 0.5 mm)                                   Up to approx. 4 kgf *

                                        Spindle pitch: 0.1 mm/0.25 mm                             Up to approx. 2 kgf

                                        Spindle pitch: 0.5 mm                                     Up to approx. 4 kgf

                         High-functionality type Spindle pitch: 1.0 mm                            Up to approx. 6 kgf

                                        Non-rotating spindle                                      Up to approx. 2 kgf

                                        MHF micro-fine feed type (with a differential mechanism)  Up to approx. 2 kgf

                * Up to approx. 2 kgf only for MHT
