  1. Sawmill parts

Promac’s reputation for quality, durability and top-of-the-line service is something you can count on every time. Each custom machined part is carefully engineered and built to the highest standard of precision by skilled and experienced craftsmen. Our specialized skills and technology include 3D scanning, heat-treating and induction hardening, and our full range of in-house capabilities means we offer the fastest turnaround time in the business.

Splined Saw

Arbors and Sleeves

Thanks to our in-house CAD facilities and CNC centres, Promac has the resources to build top-of-the-line, precision-machined saw arbors. We are proud to be one of the world’s largest manufacturers of splined arbors.

Our saw arbors are:

  • Created by precision machine hobbing;
  • Manufactured from high tensile alloy steel;
  • Hardened to 60 HRC;
  • Fully compatible with laser cut saws; and
  • Available in two formats:
    • Solid: In this design, the arbor and spline are one solid unit. The initial cost is less, but the entire unit will eventually have to be replaced
    • Sleeved: In this design, the spline slides on and off the arbor. Creating the custom arbor is more expensive initially, but will be more affordable long-term since only the spline will need to be replaced

      • Hardcoated with Type III engineering hardcoat anodized finished;
