"Precise dimensional control during the forming and extruding of components," he responds, "very tightly controlled and optimised heat treatment process; and, finally, specially formulated surface treatments on bearing surfaces and coatings on plates combine to provide highly robust interference fits and the lowest possible inter-component friction between moving parts."

Retaining compounds are used to assemble clearance, slip and interference fits. When using anaerobic materials, machining tolerances can be relaxed and rougher surface finishes can be used, removing costs from the final assembly.
As a turnkey operation, this job shop also repairs and rebuilds impellers, sleeves and nuts for finished assemblies with tight interference fits in the 0.001" to 0.003" range.
Interference fits can be strengthened or replaced by slip fits without loss of strength.
These problems can normally be prevented by using interference fits to eliminate the relative movement between rings and their shafts or housings.
Diametral interference fits of 0.0005[inches] to 0.0008[inches] headless press fit, and 0.0003[inches] to 0.0005[inches] head press fit are recommended between bushing OD and mounting hole ID to provide adequate gripping force.
