Only a couple of bucks (dollars) each. Amazing what Chinese mass production can do for the price of precision components. These bearings are very similar to the in-line skate bearings I used on HB1, being double shielded with deep races. The deep races will help with the preload and thrust loads that will be exerted by the linear screws. A very heavy duty system might possibly need thrust bearings as well as radial bearings\u00a0but I haven&#8217;t seen that done\u00a0in any of the smaller machine designs or in manufacturer&#8217;s linear screw technical specs.
