This kit contains two (2) chromium steel sealed cartridge bearings with an ABEC 3 rating.  The balls are Grade 10.  The bearings are packed with the highest quality bearing grease. 
 
This kit includes four (4) orange silicone spacer seals.  Two of the seals have an outside diameter of 41mm, which fits most mountain and road cups.  The other two seals have an O.D. of 37mm for bearing cups with a smaller seal recess.  It will be a simple matter for you to determine which seals fit into the recesses of your particular cups.
 
NOTE: For details on how the spacers are used (or not used),  please refer to the PICTORIAL INSTRUCTIONS Page.
 
 
*The bearings in our BB cup sets do not use plastic end cap/axle shims, allowing us to reduce the bearing ID and use
larger balls for greater strength!
