A sliding compound miter saw slide device allows a user to easily and accurately move a saw for proper alignment with a cutting material or workpiece. The sliding saw slide device integrates an adjustment or alignment mechanism configured to move an upper base portion of the saw base relative to a lower base portion of the saw base. In addition, a sliding saw stand allows a user to easily and accurately move a saw for proper alignment with a cutting material or workpiece. The sliding saw stand integrates an adjustment or alignment mechanism configured to move an upper miter saw mount member/plate relative to the saw stand base/base frame.

A saw slide device allows a user to easily and accurately move a saw for proper alignment with a cutting material or workpiece. The saw slide device generally includes a sliding plate configured to support an associated saw, an adjustment or alignment mechanism configured to move the sliding plate, and a base frame which supports the sliding plate and adjustment mechanism.

A stage mechanism includes a feed screw, a fixed stage having a space portion incorporating the feed screw, a movable stage, and a backlash absorbing portion. The feed screw has a first end portion and a second end portion. The stage mechanism further includes a deviation preventing portion preventing the feed screw from deviating in a direction toward the first end portion and a pressing force adjusting portion adjusting the pressing force by which the feed screw is pressed in a direction from the second end portion side to the first end portion. The deviation preventing portion is in contact with a wall of the space portion on the first end portion side. The pressing force adjusting portion is in line contact with and presses the second end portion.

Provided is a compact stage mechanism entailing little backlash and little play in a direction along the axis of a feed screw.

A stage mechanism 10 includes a feed screw 11, a fixed stage 13 having a space portion 13a incorporating the feed screw, a movable stage 15, and a backlash absorbing portion 17. The feed screw has a first end portion 11d and a second end portion 11e. The stage mechanism further includes a deviation preventing portion 19 preventing the feed screw from deviating in a direction toward the first end portion and a pressing force adjusting portion 21 adjusting the pressing force by which the feed screw is pressed in a direction from the second end portion side to the first end portion. The deviation preventing portion is in contact with a wall 13b of the space portion on the first end portion side. The pressing force adjusting portion is in line contact with and presses the second end portion.

An assembly to restrict fluid flow through the bearing section of a positive displacement or progressive cavity pump or motor. The assembly fits within the bearing chamber and includes an upper ring member, a lower ring member, an outer ring member and a floating member. The floating ring member is axially disposed between the upper and lower ring members. The floating ring member is also disposed at least partially around a drive shaft and is radially movable and constrained inwardly of the outer ring member. The floating ring member has a radial clearance between the drive shaft and a floating ring member inner surface with the radial clearance varying depending on the relative position of the floating ring member to the outer ring member.
