I haven't drawn-up a variant with the HM1 profile, yet. I was drawing a variant with a different kind of lip seal which I found on McMaster: seal, sleeve bearing.
What do you think?
Maybe it varies from one location to another. I was calling their warehouse in SF.
I suspect that's...
Bearing Egineering is local for me too (you and I must be both living in Northern California). They said that they can provide any SKF part if I give them part number or dimensions. Do you know how to look-up part numbers for the SKF's gas spring seals? Their brochure doesn't have part...
I drew O-rings only because they seem to be easier for me to find. I'm not insisting on O-rings for fundamental technical reasons. Nor am I attached to O-rings emotionally.
Lip seals would be fine. I’m in the US, and I should have first world access to parts. But I have a hard time...
Colleagues,
What are the techniques for sealing a small shaft like this one against water?
For a sense of scale, the outside diameter of the metal cylinder is around 50mm.
The purpose of this shaft is to turn a wiper that's attached directly to the shaft. (The photo doesn't show the wiper.)...
Yes, local codes will cover the mains AC wiring. I’m more concerned about the rest of the wiring.
Imagine that one needs to build a solid wire harness for an existing car engine from scratch. What's given is the working engine with ad-hoc rat's nest wiring.
What are the best practices? Clad...
The device I'm doing wiring for is a 20kW generator. It will be working semi-outdoors in a shed. It will have an internal combustion engine that will generate some vibration and heat.
Colleagues,
I'm looking for standards for rugged wiring. My gut feeling is that there are MIL and NEMA standard that cover that. If anyone knows part numbers for these standards, could you please post them?
Any suggestion, insight or reference is really appreciated!
Cheers,

Colleagues,
I need advice about a linear sliding shaft with bushing. This is a type of thing I haven’t designed before. The sole purpose of these shafts is to prevent rotation of one flat part against another. Both parts are flat plates, parallel to each-other. Plates are made of delrin...
Colleagues,
I'm setting up a fluorescence experiment with quinine as fluorescent dye. Quinine is a common fluorescence standard, that's why I chose it. The caveat with quinine, though, is that its excitation band is in near UV; peak is between 320nm and 370nm. Due to size constraints, I'd like...
Folks,
Could anyone recommend some practical books on optomechanical design? I’m mostly a circuit and software designer. I have done a moderate amount of general mechanical design too. For my current project, I need to make a relatively small optical measurement system, and I have a...
