Danfoss TMT 315 151Z3061 orbital hydraulic motor

Danfoss TMT 315, part number 151Z3061, is a fixed-displacement orbital hydraulic motor listed explicitly in the manufacturer ordering table. Its geometric displacement is 326.3 cm³/rev; the nominal size 315 is the series size designation.

This standard US execution has a 1 1/2 inch cylindrical keyed output shaft, a 3/8-16 UNC-2B shaft-end thread and a 3/8 x 3/8 x 2 1/4 inch B.S. 46 key. The SAE C four-bolt mounting uses a 127 mm pilot and a 161.9 mm bolt circle. Main connections are 1 1/16-12 UN O-ring boss ports; the drain is 9/16-18 UNF. The ordering table identifies side ports, a standard shaft seal, a drain connection and no check valves.

The current factory article page confirms the part number, photograph and lifecycle but omits its technical attribute table. The dimensions and specifications above are taken from the original manufacturer ordering, data, shaft and mounting pages included in the local PDF.

Select the operating point from the size-specific performance diagram. Continuous, intermittent and peak limits describe separate duties. Observe the original inlet/return pressure, shaft seal, shaft load and drain conditions; separate catalogue maxima do not define one combined duty point.
