Spiral Bevel Gearheads

Bevel Gearboxes include either straight or spiral teeth gears. Straight bevel gears have straight and tapered teeth and are used in applications requiring slow speeds. Spiral bevel gears have curved and oblique teeth and are used in applications requiring high-performance, high speed applications. Bevel gearboxes are mainly used in right angle applications with the shafts in a perpendicular arrangement.

Gam HPS-R

Spiral Bevel Gearboxes provide precision power transmission in single or multi-drive and/or hollow-shaft output configurations.   Our Spiral Bevel Gearboxes are highly configurable, provide backlash ratings to 6-20 (arc-min), and max torque to 5400Nm.

Gam Gears' Spiral Bevel Gearboxes:

The L Series miniature spiral bevel gearboxes are offered in two compact frame sizes (35mm and 45mm).  The housings are constructed of high strength aluminum which makes them lightweight and dissipate heat efficiently.  They are then hard coat anodized for corrosion resistance.  Numerous shaft configurations, NOTOX lubrication, and Viton / FPM seals make them an excellent choice for semi-conductor, pharmaceutical, medical, or other mechatronic applications where small size and high performance matter.  Features include:

  • Miniature size
  • 35mm to 45mm frame sizes
  • Max Acc Torque (Nm) 2-9
  • Lightweight aluminum housing
  • Non-toxic/food grade lubrication
