Hi geesamand,
Good to know not expect tight accuracy with the McMaster-Carr cad models. I admit I did think that. Fortunately I only used cad models for fasteners from there. I did download the exact bearing from SKF and I was pleasantly surprised that the model was the complete bearing...
Hi Tmoose,
The information on page 20 is interesting. I had asked SKF about housing clearance but I decided to check it one more time and sure enough I found a mistake that made the housing bore outside of the range suggested. I decided to confirm my shaft diameter was correct and it turned out...
Hi David,
A rough guess is 50 RPM with a 3 pound load. I included friction in the cad simulations but the parameters used are the program defaults for the most part. I have not included heat build-up and I’m sure the parameters could use adjusting. I will follow your advice and only experiment...
That’s a way cool experiment, thanks for sharing it. I was definitely tempted to take the shields off but you backed up what I’ve seen others mention including your point regarding rubber seals vs. metal shields.
I had no idea that dust would be a real factor in an average environment. With...
Thanks for the responses. Every point made here and on thread821-269031 is exactly the same as when talking with a bearing engineer. I hope it’s OK but I’m not an engineer but have a passion for 3D cad design. I use Autodesk Inventor and have a habit of designing things that are expensive no...
I’m looking for a low friction bearing for a slow rpm balancing kinetic art project. The bearing needs to be an easy startup type. I plan on removing the grease and using light oil. I was considering the Bones Ceramic Skateboard bearings but another thread here mentioned that these bearings were...
