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.

How do I find the right part for my system?
Three options. Search by part number if you have the OEM code from Parker, Danfoss, Linde, Kawasaki, Kayaba or Grundfos — our search recognises both manufacturer codes and aftermarket cross-references. Browse by category if you know the component type (pumps, valves, cylinders, etc.). Or send a spec sheet to our engineering desk and we'll cross-reference against our 3,000+ SKU catalogue within one business day.
Can you help me size a pump or valve for my application?
Yes — sizing support is included with every order. Send us your operating pressure, flow rate, viscosity, drive speed and duty cycle, and our engineers will recommend a suitable component from our catalogue with full datasheets. We don't custom-build parts ourselves, but we can spec the right OEM component for almost any standard industrial application.
Can you cross-reference a discontinued part?
Yes — cross-referencing is one of the things we do most. Send us the original part number (even if the manufacturer has dropped it) and our engineering desk will identify a current equivalent or compatible alternative. Cross-reference lookups are free and typically come back within 4 business hours.
