Please Buy With Confidence!
I have sold THOUSANDS of knife grinder wheels to buyers all over the world, with ZERO complaints! I sell these EXACT wheels to a number of Professional Knife Belt Grinder Manufacturers for use on the grinders they sell. I am the only seller on ebay that includes a spacer between the bearings to prevent over tightening that may cause damage to your bearings (this is very important).
This listing includes a single 2" Idler / contact wheel. This wheel is made of billet 6061 aluminum right here in the USA on a precision CNC lathe center.
This platen wheel is 2" in diameter and 2" wide. It has a pressed in sealed ABEC 3 radial ball bearings and contoured edges to aid with belt tracking (this wheel is typically used with a flat platen or slack belt attachment on the belt grinder)
There is a spacer between the bearings to help prevent over tightening. Some wheel sellers don't include this important feature.
The inside diameter of all bearings used is 1/2". Make sure the hardware you use to mount the wheels does not contact the inner and outer races on the bearings at the same time
