Oil nozzle sizing

[Pimech]

Hi,
I'm sizing a lubrication system for a transmission gearbox.
According to flow rate and pressure generated by oil pump, I've calculated a nozzle size of 0.7mm to lubricate a ball bearings.
Is it a feasible hole size for a nozzle in a lubrication system?

Thanks
Pierluigi

Why do you want a nozzle? What do you expect it to do?

Please excuse my english, I made a translation mistake.
The oil is supplied to the bearings through a gallery whose diamater is 0.7mm.

Yes, you could put an orifice in with that sort of hole size - but your oil has to be very clean (no big bits of debris floating round) otherwise the hole will block up.

What sort of flow rate are you expecting? Just check that the velocity through the jet isn't too high. Anecdotal evidence is of the fluid jet actually drilling a hole in the housing at the point where the high velocity fluid stream struck.

The attached datasheet is just one place where you can buy the jet you want. You can also get them from Sun Hydraulics.

Thanks Oldhydroman. Expected flow rate is 0,7 lit/min.
