CBN self aligning spherical washers?

[Barry Larson]

I am just about to order a set of CBN wheels (180 and 600 grit) for a stripped down 1 hp slow-speed Rikon grinder I bought. The website lists self aligning spherical washers for the wheels and I am wondering how important these are to the performance of the CBN wheels?
Any and all information is appreciated.
Thank you.

I would vote for very important ... I used them on mine, came with the wheels. From a Google search ... for what it's worth ...

"...... Spherical washers are designed to correct misalignment between bolted surfaces. The self-aligning feature of spherical washers is crucial because it allows the washers to automatically adjust to angular misalignments between surfaces, which ensures even load distribution, reducing stress on fasteners and preventing damage to components in applications where surfaces are not perfectly parallel. By compensating for these misalignments, the self-aligning feature enhances the performance, durability, and safety of assemblies, especially in industries like automotive, aerospace, heavy machinery, and construction. This feature is essential for maintaining the integrity and efficiency of bolted connections under dynamic and heavy loads. ....."

Personally, I would say very important, If you dont use them the pitch of thread on the nut causes the wheel to follow the thread pitch and puts it a slight angle causing a slight wobble and vibration. which then transfers to your tool as a slight vibration

Thanks Steven. I will acquire the washers to go with the wheels!

Cheers.
