Wheel & Axle - GS 301

Wheel & Axle.

This design of the traditional wheel and axle eliminates the usual cumbersome fork and pointed pivot bearings and replaces them with a simple axle and simple bearing.

The GS 301 has four pulley steps, each with a small hole drilled in the rim for attaching string. The stainless steel axle is mounted in a ball bearing which is embedded in the center of the molding. (Shownd at bottom of illustration.)

Wabash #GS 301.
