I would like to understand why some same pitch timing belts and pulleys are available in 20 and 21 mm widths and if there is any reason I should not use a 20 mm belt on a 21 mm wide pulley.

I can't imagine that this isn't a common design problem. I am driving two rollers, one stationary and one that moves from a position of contact with the stationary roller to a position that creates some clearance between the rollers. The simplest way to move the second roller is to mount it on a...
We are looking at a reduced availability of MIC-6 Cast Aluminum Tool and Jig material which we have used for years for our heated seal dies. An alternative called CAST5000 has been suggested by our vendor. I need to confirm that it is acceptable and have tried to collect properties for both...
We slit plastic film with a round slitter blade. The film is stationary and resting on a ground hardened plate. The blades are pneumatically actuated forcing them down against the film and then advanced along the film for the length of the cut, after which the blade is retracted and returns to...
The machine in question manufacturers flexible packaging using various films one example being polyethylene. Part of the process pulls the film over a triangular folding board whose edges can be made from various metals, such as stainless steel or aluminum. We have used various treatments and...
I am doing a Risk Assessment on a production machine using ANSI B11. It is not clear to me exactly what is meant by Probability level and Exposure level.
Probability is described as: "The likelihood that an individual, when exposed to the hazard, will suffer the consequence" and the levels vary...
I'm am designing a belt conveyor that transports thin polybags from where they are cut free from a roll to a packing table. I believe the transport of these practically weightless bags are not significant enough to include in any initial calculation. So the pretension and running tensions for...
I am wondering what the accepted method for detailing retaining ring grooves on a shaft or in a housing, with the purpose of locating a ball bearing axially.
Are the inner faces of a pair of grooves, which are meant to retail a bearing between them, set at the nominal bearing width? Wider to...
