Our aluminum ratchet sheaves ring gear are precision-machined from high-strength, corrosion-resistant aluminum alloy, specifically designed for marine rigging and sail control systems. The built-in ratchet mechanism provides reliable one-way locking functionality, allowing smooth line take-up while preventing unwanted reverse slippage under load. Lightweight yet robust, these sheaves feature a precision-grooved wheel profile that ensures smooth rope guidance with minimal friction and wear.

Ratchet Sheave ALU Ring gear For Marine Rigging & Sail Control System
Aluminum ratchet sheaves are essential components in sailboat and marine vessel control systems, widely used in mainsheet systems, jib sheet leads, halyard winches, and vang controls. In these applications, they enable sailors to manage sail trim with significantly reduced manual effort, as the ratchet mechanism generates holding power that resists rope creep under tension. Ideal for dinghies, day sailors, and cruising yachts, our ratchet sheaves perform reliably in continuous exposure to saltwater, UV radiation, and varying weather conditions. They are suitable for both OEM installations and retrofit replacements, helping to enhance onboard safety and sailing efficiency.

Tube Forging
When gears need high performance that needs to withstand high loads, high stress, impact loads or fatigue loads, forgings are suggested to use. Forging allows metal fibers to be continuously distributed along the gear profile, significantly improving root strength and fatigue life.
Turning
This is the process of cutting and shaping solid materials into precise parts. It uses tools like lathes, mills, and drills to remove excess material. Machining transforms a simple block of metal into a finished, functional component.
Internal Gear Shapping
Gear shaping is a gear cutting process that used cutting tool that is essentially a “master gear” reciprocates while meshing in a synchronized rolling motion with the gear blank.The cutter is usually moving up and down.
Heat Treatment
Gears need to be running with two gears or above two gears, that makes them easy to be worn-out. That’s why most types of gears need to be harden through heat treatment.
Ring Gear Grinding
Gear Grinding is the the most common high-precision method for finishing hardened gears under gleason profile. There are two methods to use an abrasive grinding wheel removes material from the tooth flanks.
