bushing/shaft chart
bushing/shaft chart
(OP)
I'm specifying a bushing for a 6" dia x 11.75" S7 steel pin that will take a 300 ton load (mounted on the end of a large hydraulic cylinder) and I was wondering if anyone out there has come across a standardize chart for bushing types with varying loads. The machinist handbook only goes to 1". The bushing will likely be mild steel, however I'm not sure what OD would be best for such a load and if applied stress over a given surface area will have an impact on life.
Thanks in advanced

RE: bushing/shaft chart
Could you the forum why the S7
You might want to look at links below to give you some idea of the size required. The first link is to CRC who is now Hydrotech
they build very large hydraulic cylinders.
The second link is to CRC Component Parts catalogue to see what's available.

RE: bushing/shaft chart
Thanks for the links. Unfortunitely the calculator wont let me specify the cylinder I need. 12" ID X 164" Stroke, 345 bar. There isn't a shock load and very little rotation (no more than 3 degree's). We've used S7 steel pins for some time on our cylinders and I'm just trying to figure out what size bushing (relative to pin diameter and applied force) to use. I'm not sure what to use besides a guess without data to back it up. Thanks in advanced for your help.

CRC Mfg. built some awfully large cylinders and if you look at
the Applications section on the Hydratech web page the pictures
are from the old CRC Mfg.web page.
Here are two sites that may help. The RBC site has high spherical.Spherical bearings. The Connex site is for spring steel tension bushings. They may go to 6" as they only list 5.5"
