I'm using their round bushings (a direct replacement for Sintered Bronze).
I' couldn't be more pleased! They seem to do everything they are supposed
to--can't tell about wear yet as they haven't been in service that long.
The important part of installation is to have diameter of the housing
correct. The bushings need to be compressed to give rated accuracy.

My machine is all MDF so I turned aluminum sleeves for the bearings,
pressed them in and epoxied the aluminum into the MDF.

The best part of the equation is the price!
