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.

Normal spaces vary from one-half the drill diameter for small chips as from cast iron to one and one-half times the drill diameter for long stringy chips as from cold-rolled steel.

For other conditions, e.g. where both rings are mounted with an interference fit or where unusual temperatures prevail, bearings with greater or smaller.

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.

Bushing Installation A bushing should be developed to withstand the electric field strength created with the insulation, whenever any earthed material is present.

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.
