Overview

When shafts intersect, bevel gears carry the load. We produce spiral, straight, and skew (hypoid-style) bevel gears and matched pairs for right-angle drives, engineered for correct tooth contact and long service life under shock and reversing loads.

Key features

  • Spiral, straight, and skew bevel geometries
  • Matched pairs lapped for correct tooth contact
  • Right-angle and intersecting-shaft arrangements
  • Carburized and hardened for shock-load durability
  • Replicated from worn samples through reverse engineering

Spur Gears

Spur Gears

Precision straight-tooth spur gears cut to AGMA 11 in diameters up to 160 inches — the workhorse of heavy power transmission.

Helical & Double Helical

Helical & Double Helical

Single, double helical, and herringbone gears for smooth, quiet, high-load meshing in demanding drivetrains.

Worm Gears

Worm Gears

Worm and worm-wheel sets for high reduction ratios, compact drives, and self-locking motion control.
