20ST Orbit ST Winch - One-Speed

Ronstan’s Orbit Winches™ are the new benchmark in high performance alloy winches. With a combination of fresh design thinking and proven manufacturing expertise, Orbit Winches™ weigh significantly less and offer lower line entry heights than any other winch in their class.
Remarkably easy to service, they require no tools for disassembly or maintenance.

The fully machined aluminium drums feature the same Power Ribs™ that many will recognize from Andersen Stainless Steel Winches®, well-known for their impressive line grip, smooth control, and minimal rope wear.

Features –
• Sprung self-tailing jaws to accept 6 - 10mm (1/4"-3/8") line
• Proven Andersen winch gearing configuration
• Distinctive drum Power Ribs™ ensure a controlled grip on the line at all times, whether trimming or easing. Minimal rope wear compared to more abrasive drum surface finishes
• No tools required for configuration and servicing
• Lightweight machined aluminum drum – stronger and lighter than traditional cast aluminium drums
• Aluminium center stem, lighter weight compared to bronze stems
• Low line entry due to advanced gearing configuration geometry
• Note – Among the Orbit Range, this 20ST Single Speed is the only winch which does not have the unique QuickTrim™ feature

Power Ribs
Inspired by the distinctive drum profile of Andersen winches, Power Ribs™ have been incorporated into the fully machined drums of Ronstan’s Orbit Winches™ to deliver the same impressive line handling with maximum grip and minimal rope wear.
The exceptional grip provided by the Power Ribs™ offers a multitude of benefits — requiring fewer wraps around the drum, reducing the load held in the self tailer, and encouraging the line to slide easily upward on the drum to avoid riding turns. The non-abrasive drum surface extends the service life of running rigging and allows for smooth and controlled easing, even under high loads.

No Tools Required for Disassembly for Maintenance
Full disassembly and reassembly can conveniently be performed without the need for any tools.
To remove the drum, pull back the spring-loaded release latch on the top of the winch, then a slight counter-clockwise rotation will allow the self-tailing arm to be lifted from the winch. From there, the drum can be removed from the winch center stem.
When completing reassembly in the reverse order, an audible click confirms positive engagement between the self-tailing arm and bayonet notches on the center stem. These notches allow the self-tailing arm to be locked in one of eight positions at 45° rotational increments.
