the mvn50 precision ball bearing vertical linear stage provides precise 0.31 inch manual height control with micron-scale sensitivity. its high load capacity makes it especially suited to vertical positioning of heavy payloads. the stage utilizes an inclined plane design consisting of two precision-machined, opposing wedge blocks. horizontal translation of the lower wedge is transformed into vertical motion of the upper wedge by means of inclined ball races. for linear, backlash-free travel, ball races are fabricated from precision-ground tool steel and are pre-loaded by a spring. a rotation of one division on the micrometer scale corresponds to a vertical displacement of half the linear displacement distance, thereby doubling the sensitivity. manual positioning sensitivity can be approximately 50 nm using the dm series of differential micrometers. this stage has a large mounting platform that incorporates an array of tapped english mounting holes for the convenient attachment of components.actuators are sold separately. please note theminimum and maximum height specs below include a 6-mm thickness of the m-pbn5base plate which is sold separately.
