Torque (Pitch/Bolt) to Axial Force - Mechanical ...

11-03-2009· Using the 15lbf-in torque on a 7/8" diameter screw I get a load of 2.625lbf with the formula you have provided. Normally to create a seal with an 'o' ring you compress the thickness or cross section of the 'o' ring by a %, usually off the top of my head about 15-30% of the section size. One full turn of your screw will compress the ring by 0.031".

Biomass screw feeding with tapered and extended .

01-08-2008· Biomass screw feeders operate in a manner similar to piston feeders, but have a somewhat lower pressurization range (0.5–1.5 MPa). In a screw feeder, an auger compresses the feedstock into a compact plug, aided by tapering the feed channel, or by gradually reducing the pitch of the screw.
