I was starting to look at ceramics last night. I have no experience with them. I know they will handle the heat but do not know if there are FDA rated ceramics. I'll investigate today. Thanks for the help, Dan

We tried a test yesterday afternoon but blew the circuit after 5 min. We are trying again today. I assumed 1,200 f as the elements are generating 1,500 to 1,600 f at 4" away.

Good Morning, I have an FDA application. A heater element that reaches 1,600 deg f. located 4" above the a 303/304 Stainless Steel belt. I need a wear rail for the belt that won't melt. We are leaning toward a non-metalic component so we dont get micro-particles from metal on metal. Any...

Thanks Syd, They've got an easy to search web site with stock listings as well! You've been a big help, Dan

Good = Not Junk. My speeds and loads are generally light. Stock = Stock. On the shelf. Ready to ship. Thanks, Dan

Try Bostons BEAR-N-BRONZ Series. It is an SAE660 Cast Bronze Bearing that has saved me in som high shock applications.

dimjim is correct, Socket Head Cap Screw

Does anyone have any recomendations for a good stock stianless steel imperial bearing with seals? I use 3/8, 3/4, 1, and 1-1/4 ID's. Thanks, Dan

Hi Bill, The Drive Pulley is the one giving us problems. Yes it is the larger of the pulleys in the system. We are confident there is a welding problem that we are looking into with the manufacturer. I have a couple of engineers working on verifying the overall pulley design. That is where...

dwt, Yes there are weld issues going on. I have information coming in from the feild from other units where there are stress fractures at the centerline of the weld about the diameter. We are also looking at the thickness of the hub. Basically we have been specifying the same pullies for...

Thanks Dave, We have pulleys being analyzed at the University of Iowa's metalurgy deopartment now. My boss asked for the formula. He's in meetings with the President, Purchasing Manager, and Quality Control. (Notice the absence of an engineer in that group?) I can formula the belt pull for...

We have drive pulleys failing in the feild where the hub of the pulley is welded to the shaft. I have been asked for a formula for a relationship between Torque on a shaft and belt pull. Is the torque the difference between the tension side and slack side times the radius? This sounds to...
