Slip fit tolerance for 37mm dia. part

AI Thread Summary
For a steel component with a diameter of 37mm, a loose slip fit is required for easy insertion and axial stability. The fit should allow the component to fall through when held vertically, suggesting a diameter slightly larger than 37mm, typically around 37.1mm to 37.5mm. Operating temperature is a crucial factor, as thermal expansion can affect the fit; what works at 20°C may not at 100°C. Reliable references for fits and tolerances can be found by searching "fits and tolerances" online. Proper consideration of these factors will ensure the desired functionality of the assembly.

I have a steel component ∅37mm (O.D.) and looking for material/guidelines on a loose tolerance for the housing surrounding it. It needs to be able to fall straight through if held up vertically, easily insertable by hand, while still providing enough axial stability. What's a good diameter for this and is there any reliable references/tables for applications like this? Thanks, much.

I can't help thinking that your range of operating temperatures will have a big impact upon the answer. Something that's a loose "slip fit" at 20° might very well seize at 100°.

Thread 'Bubble formation in 4 mm gap vessel'

How did you find PF?: Via Google search Hi, I have a vessel I 3D printed to investigate single bubble rise. The vessel has a 4 mm gap separated by acrylic panels. This is essentially my viewing chamber where I can record the bubble motion. The vessel is open to atmosphere. The bubble generation mechanism is composed of a syringe pump and glass capillary tube (Internal Diameter of 0.45 mm). I connect a 1/4” air line hose from the syringe to the capillary The bubble is formed at the tip...

Thread 'Physics of Stretch: What pressure does a band apply on a cylinder?'

Scenario 1 (figure 1) A continuous loop of elastic material is stretched around two metal bars. The top bar is attached to a load cell that reads force. The lower bar can be moved downwards to stretch the elastic material. The lower bar is moved downwards until the two bars are 1190mm apart, stretching the elastic material. The bars are 5mm thick, so the total internal loop length is 1200mm (1190mm + 5mm + 5mm). At this level of stretch, the load cell reads 45N tensile force. Key numbers...

Thread 'Find 3D Printer & Software Resources for Prototype Creation'

I'd like to create a thread with links to 3-D Printer resources, including printers and software package suggestions. My motivations are selfish, as I have a 3-D printed project that I'm working on, and I'd like to buy a simple printer and use low cost software to make the first prototype. There are some previous threads about 3-D printing like this: https://www.physicsforums.com/threads/are-3d-printers-easy-to-use-yet.917489/ but none that address the overall topic (unless I've missed...
