Product Overview

The Hydraulic Orbit Motor series including models 6K-490, 6K-390, 6K-400, and 6K-310 is designed for high-torque, low-speed hydraulic drive applications. Built on a cycloid (gerotor) motor design, these units deliver smooth rotational performance, strong starting torque, and reliable operation in demanding mobile and industrial systems.

Commonly referenced with part numbers 612-2045, 620-0014, 612-0085, and 612-1023, this orbit motor range is suitable for heavy-duty hydraulic circuits requiring consistent torque output and compact installation. Its robust construction ensures durability under continuous operating conditions.

// What customers say

Trusted on the shop floor.

Engineers, plant managers and procurement teams who keep coming back.

Sourced an obsolete Parker valve in 48 hours when the OEM had a 12-week lead time. Saved a $40k machine from sitting idle.

Mark T.Maintenance Lead · Brisbane plant

Their engineering desk caught a sizing mistake in our spec before we ordered. Saved us from buying a pump that wouldn't have moved enough oil for the duty cycle.

Sandra K.Hydraulics Engineer · OEM

The cross-reference service is the reason we switched. Send a part number, get a real answer with a real datasheet — not a sales pitch.
