Power Transmission
& Gear Machining

Transferring power efficiently requires precision components assembled together, and that requires precision machining. For decades, Tech-Mac has machined couplings, spacers, adapters, gear and pinion blanks for industries such as mining, construction, transportation and oil & gas. High quality materials are a must and material traceability is standard operating procedure in our shop.



Core Competencies

  • Common parts: spacers, adapters, couplings, gear blanks, rigid spools, hubs, sleeves, pinion blanks, crankshafts, double flanged hubs, universal joints
  • In house large part WIRE EDM capacities to cut to 20" thick: keyways, splines, critical cut outs, contours, hardened materials and exotic materials
  • Value added secondary services: heat treating, grinding, broaching, painting, coatings
  • Materials: specialty alloys, bearing quality grades, carbon steels in forgings and bar stock
