Mini No-Support Pulley (608) – Pure Zero Mini

Compact minimal pulley using a single 608 bearing.
No supports; keyed compression pins (tap to seat).

A mini version of the amazing Pure Zero Pulley but without the bottom ring. Just one 608 bearing is required.

PURE - no supports required
ZERO - no metal bolt required

Assembly

The axle is a two-piece compression-fit pin that must be hammered into place. The pins are keyed to make it fool-proof to get them inserted properly. To get them all the way set into place I recommend using the butt end of a screwdriver or a plastic hammer to avoid damaging the part.
