ISO 9409-1-A Flanged Pinions

We have recently expanded our range of ISO 9409-1-A flanged pinions.  This allows the machine designer the flexibility of choosing the best flanged pinion to meet the application needs.

The new TR flanged pinions have compact designs to reduce the amount of drive torque required.  Traditionally, flanged pinions have large pitch diameters which increase the amount of torque on the reducer they mount to.

With the new TR Pinion range, the pinion pitch diameters are significantly smaller, reducing the drive torque required and allowing a smaller reducer to be used.  The pinions are easily mounted and replaceable if future repair is needed.

This hardened & ground pinion range has a quality level of DIN 5 and is available in straight (spur) and helical-toothed versions, in metric modules 2.0 through 8.0.  The pinions can mount to any reducers with ISO 9409-1 flanged connections, see table below.

The combination of the TR pinions, with their low inertia and high accuracy, used with ATLANTA’s precision gear racks, make it possible to achieve very highly dynamic axis drives with high precision and repeatability.

Below is a list of the various ISO interfaces and the pinion sizes available.  For a PDF catalog on the part, please click on the part number.
