Minimum interference of housing and bushing: Tolerance of interference fit (sum of ISO IT Grades 6 & 7): Bushing ID shrinkage factor due to interference: Maximum bushing ID shrinkage due to interference: Minimum running clearance (ISO Shaft Deviation Limit f): Total tolerance for clearance (sum of ISO IT Grades 7 & 8.
The bushing internal clearance shall be selected so that when bushings are mounted with recommended fits, and operate under normal conditions a suitable operational clearance will be obtained. For other conditions, e.g. where both rings are mounted with an interference fit or where unusual temperatures prevail, bearings with greater or smaller.

Feb 22, Generally per inch of diam is a good fit for bronze bushings. As said, if you press or shrink a bushing by, expect a reduction in ID, as well. If you can heat a 5" bore housing up to about F and freeze the bushing, you should have about clearance to slide it in before it binds up.
Press fit or shrink fit bushing design and installation is a common method of retaining bearings by use of interference between the bushing and the bushing hole. Bushings are available in standard sizes with both inside and outside diameters surfaces finished, and are commonly available in many sizes.
Mar 08, The rule of thumb as far as I know was per inch of OD bore. If you press a bushing into a bore you best bore the bushings ID to"+. Never make a bushing too tight, it will shear off the press fit and just fall out later.PM #
