@Kyle Loctite is already in use.

@stick Tapered- lock bushing will significantly increase the cost. Perhaps not feasible as a result. Shaft diameter is 0.163 in. Bore diameter is 0.156 in.

@BUGGAR and @chez311 It is a straight knurl. Diametrical Pitch 96.

I have a knurled interference fit between a shaft and a gear. With an interference of 0.007 in, I am achieving an experimental slip away torque of 7 ft-lb and bending the shaft in the process. What could I possibly do to achieve a higher torque without bending the shaft during the assembly? Both...

Could someone please recommend modifications/reinforcements that could be made to a pipeline to reduce its vibration? Installing a pulsation dampener is not an option that the customer is willing to pursue. Currently, the vane pump sits on a solid base as recommended by the manufacturer and flex...

EdStainless Based on your statement, will the below expressions suffice? Thank you. OD (Temp) = OD (293) + alpha (Temp) ID (Temp) = ID (293) - alpha (Temp)

rb1957 If the cross-section were to contract with the expansion in length, would the Poisson's ratio figure in the expression?

EdStainless and rb1957 I perhaps should have asked, if the percent change in the length of the tube for a given temperature difference is the same as the percent change in its diameters individually?

I have a 316 SS tube with an I.D. of 0.43″ and O.D. of 0.5 ″. Could someone please advise me on how I would calculate the I.D. and O.D. of the tube at cryogenic temperatures? The linear thermal expansion percent (L – L293/L293) at a temperature range (0 K – 300 K) is the only material property...

No, the frequency is not being used as a measure of stiffness. When heated or cooled, the boundary conditions will resist the change and generate stress in the tube. I am using the equation listed in the Cryogenics NIST website to define Youngs Modulus as a function of temperature.

I have a simple omega-shaped SS tube, vibrating at it's natural frequency and constrained at both the ends. Could someone please tell me how I would calculate it's stiffness as a function of temperature. The temperature range I am looking at is 5K to 300K. Thanks in advance!

Could someone please suggest a reliable resource containing information on Youngs Modulus for 316 Stainless Steel at Cryogenic temperatures? Thanks in advance!

Could someone please recommend a polymer to be over-molded onto a metal surface to create a soft seat valve? This valve will be used in LPG applications. We are currently using Buna-N and it appears that the liquid has gotten between the metal and the rubber and caused the rubber to balloon...

My supplier is out of 260 Cartridge Brass - Hard Temper which is being used to manufacture flat washers. Can somebody advise me, if the half hard temper which is readily available be used as a replacement? Thanks in advance!

Additional information: The deposit was sent to analysis and the EDS spectrum indicated the presence of Oxygen, Copper, Zinc, Lead and Tin.

I have metal to metal contact between leaded brass and aluminum components. The aluminium is Nituff coated and sits inside the brass body. The only fluid that this combination comes into contact with is refined fuels. A dirty green colored deposit is being observed from time to time on the inner...
