Bonded Gearshafts
Bonded Gearshafts

One of the products we specialize in manufacturing at Jrlon is a bonded gearshaft for use in pump applications. Depending on quantity needed, a filled PTFE gear blank is either compression molded or injection molded over a ceramic or steel shaft. Once the PTFE blank is properly cured to ensure long wear life, gear hobbing equipment is used to cut the teeth to the desired dimensions, and the entire piece is finish machined to within ±.001” tolerances. Each piece is bubble wrapped and boxed for shipment to your location. Useful for applications that require heat and chemical resistance, these PTFE gearshafts are available in quantities from prototype to high volume production.
