PV Limit for steel bearings

[serdart]

Hello,

Some earthmoving machinery have hardened steel bushings instead of bronze ones. They are made of x MnCr 4/5 and hardened to +50 HRC.

I need the PV value of such bushings. Internet is full of information for the new ones (sintered bronze/graphite, PTFE etc...) But There is no info for turned hardened steel bush. Any info is appreciated, however academic data is preferred.

Thx

The Vogelsang Corp. has the information you require for one particular material. As they make Tension bushings from different material one has to be careful.
All the data you need is here, but the site is a little convoluted, so your mouse has to do the walking.
