Press Fit Steel Pin Into Aluminum

Spiral vent pull out dowel pins a spiral groove cut into these pins relieves trapped air but stays in 360 contact with the hole for a secure fit that s easy to insert in and remove from blind holes.

Press fit steel pin into aluminum. Lubrication is frequently used in the press fitting of compliance pins in pcbs to reduce board stress due to undue press force according to lowery. Let s say you ve used a one inch nominal aluminum pin in a hole on a 410 stainless steel part with 0 0007 inches of diametrical interference. Depending on the amount of interference parts may be joined using a tap from a hammer or pressed together using a hydraulic ram. The force required to assemble press fit cylindrical parts depends on the allowance or clearance between the cylindrical parts for the fit area of the positioned and fitted surfaces the pressure increasing in proportion to the distance that the shaft feature is forced in.

Critical components that must not sustain. To remove thread a screw or tool into the tapped hole then pull the pin out. How cold can it get before the shrinkage completely negates the interference. Pin shaft press fit force equation.

An interference fit also known as a press fit or friction fit is a form of fastening between two tight fitting mating parts that produces a joint which is held together by friction after the parts are pushed together.
