This is description of this part:
Complete focus block for the Olympus CX31 / Olympus CX41 microscopes.
This is the complete module responsible for raising and lowering the stage and condenser assembly. It consists of the following parts:
- load-bearing metal casting to which the remaining parts are screwed (manufacturer's name: frame)
- brass rack fastened with two Allen screws (manufacturer's name: rack). This is the main rack that lifts the whole mechanism. Because it carries the entire load, this is a part that often gets damaged while the microscope is being transported
- outer guide with five screws used to adjust the lateral pressure and the running resistance (manufacturer's name: outer guide). It is the loosening of this part that is often responsible for the microscope stage sinking down on its own
- tracks on which the rollers run (manufacturer's name: wire guide)
- two brass plates with rectangular windows that keep the rollers evenly spaced (manufacturer's name: casing). These often get bent, which makes the vertical movement of the stage lose its smoothness
- set of 16 steel bearing rollers, 8 per side (manufacturer's name: roller). These often fall out and get lost after a mechanical impact or during servicing of the mechanism
The last photo in the gallery shows the frame of the Olympus CX31 microscope, with arrows indicating which parts are meant and where they are located in the microscope.
What is this part needed for?
- as a service part, when the complete vertical movement module needs to be replaced
- when one of the individual parts of the focusing unit needs to be replaced
- when you are building your own DIY project and need a precise mechanism running on cylindrical roller guides
