Newly Re-designed P-Series Gearbox improves Backlash, Corrosion Resistance and Center Distance between Input and Outputs! 

Flange Mounted Gearbox Systems

Flange Mounted Gearbox Systems produce an output at 90° from the input and are built with compact footprints, making them ideal for a wide range of applications. Single-ended or double-ended output shafts are available for even greater versatility. Manufactured with durable, high-quality materials and sturdy craftsmanship, PF and PFA flange series gear reducers will stand up to even the most challenging working conditions.

Flange Mounted Gearbox System Design Changes

As part of our commitment to existing product improvement, Ondrives.US is revising the design of our P, PF, and PFNM gearbox models. These design changes will improve quality and consistency and eliminate the requirement for the eccentric output design of the low (-A) and further reduced (-AR) backlash versions. Potential improvements over previous versions include:
  • More consistent center distances
  • Smoother and quieter running
  • Reduced environmental impact
The external dimensions of the gearboxes, including casing size, input shaft and output bore sizes, and mounting hole positions and diameters will not be affected. However, the gearboxes will look visually different, the large black steel output mounting is replaced with a stainless steel mount.

Flange Mounted Gearbox System Advantages

Ondrives.US offers a variety of torque values and shaft input sizes. All flange gearbox models provide low backlash (≤30 arc minutes backlash or less) and high efficiency (as much as 90% at 1,000 RPM). Additional Flange Mounted Gearbox System advantages include:
  • Highly efficient worm wheel gear reducers (up to 90% at 1,000 RPM)
  • Twelve different frame sizes, output torques from 0.94 Nm to 164 Nm
  • Standard ratios from 5:1 to 120:1, custom ratios available
  • Solid aluminum housings and steel interior components
  • Single- or double-ended output shafts (purchase separately)
  • Low backlash—as low ≤4 arc minutes
  • Greased for life
  • Ball bearings on input and output
  • Optional motor inputs available
  • Custom gear reducers are available
