The PGR PCD series consists of cycloidal gearboxes with a design that differs from conventional gear units. Its key feature is that motion is transmitted by drive elements rolling over each other, rather than by gear teeth sliding against each other as in ordinary gearing. This meets the demand for compactness, high ratios, small size and product reliability.

With coaxial input and output, the series covers 0.12–95 kW, 3–74490 Nm and ratios of 6–7569. Foot-mounted, flange-mounted and housing-mounted versions are available for horizontal and vertical mounting positions, and the unit is supplied with a solid output shaft. Input options include motor-coupled, PAM, W and C-face.

The discs are made of 100Cr6 steel and the rigid housings, which are suited to heat transfer, of GG25. Single-stage units up to size 612 are grease-lubricated and sizes 613–620 run in an oil bath; for double-stage units, sizes 607/07–618/10 are grease-lubricated and 616/11–627/19 run in an oil bath.
