Parallel shaft gearboxes

Series Z


Parallel shaft gearboxes stand out for their strength and application versatility, which make these types of gearboxes suitable for medium-heavy industry application. These gearboxes guarantee high resistance to radial and axial load and they are recommended for heavy-duty application as agitators, stone crushers, plastic extrudes, bucket lifters, molds, fans and similar.
Parallel shaft gearboxes are available in 6 sizes with single reduction stage, in 6 sizes with two reduction stages and in 6 sizes with three reduction stages.

  • Power up to 270 kW
  • Reduction range 5 to 250
  • Torque range T2M = 180 - 11500 Nm

Two input types are available: with projecting input shaft, with pre‐engineered motor coupling (bell and joint).

The gear unit body in engineering cast iron for size 71 ‐ 90 – 112 – 125 – 140 – 160 - 180 or spheroidal graphite cast iron for size 200 ‐ 225.

The use of high‐quality tapered roller bearings on all shafts ensures long life and enables very high external radial and axial loads.

Accessories to be implemented to parallel shaft gearboxes are:

  • Output shaft
  • Mounting and dismounting kit with hollow output shaft
  • Hollow output shaft with shrink disc
  • Output flange
  • Torque arm
  • Hollow shaft protection kit
  • Backstop device

Spare parts list is available on the technical catalogue HELICAL AND BEVEL HELICAL GEARBOXES.
