Steel V-Wheel

This is a chrome steel V-wheel, identical to the popular industrial RM1ZZ, except it has a 5 mm diameter hole.  It is a dual-row angular-contact ball bearing, with a 90-degree V groove on the outer race.  In other words, it's a one-piece V-wheel, with built-in bearings.

The steel V-wheel is much more solid than the standard MakerSlide Delrin wheel.  It is rated for 1000 N static loads (100 kg) and 1500 N dynamic loads (about 150 kg), both in the axial and radial direction.

However, the steel V-wheels are slightly smaller than the Delrin wheels, so they aren't a direct replacement.  In time, they will destroy regular aluminium MakerSlide.  We recommend running these on hardcoat anodized MakerSlide.
