Belt Grinder Knife Grinder wheel set. 2 @ 2"x 2" idler contact wheels , 4" tracking

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 Two 2" Idler/contact wheels and One 4" Crowned tracking wheel. These wheels are made of billet 6061 aluminum right here in the USA on a precision CNC lathe center.  These wheels are tried and true.  They  are in use by various big name custom knife makers and even some OEM grinder manufacturers.

The 2" wheels are 2" in diameter and 2" wide. They have pressed in sealed radial ball bearings and contoured edges to aid with belt tracking (these wheels are typically used with a flat platen attachment on the belt grinder)  There is a spacer between the bearing to help prevent over tightening. 
The 4" tracking Wheel is 4" diameter and 2.5" wide.  It is crowned to help with belt tracking and it also has the spacer between the bearings to prevent over tightening.
The inside diameter of all bearings used is 1/2". Make sure the Method you use to mount the wheels (I just use a 1/2 bolt with no washer and a nut on the other side) does not make contact with the inner and outer races on the bearings at the same time causing it to bind.
